Essex, with its rich architectural heritage and diverse property styles, offers homeowners excellent opportunities to expand and enhance their living spaces through house extensions. From traditional cottages to modern townhouses, extensions can add value, functionality, and aesthetic appeal to properties across the county. Construction Inc, your trusted local builders in Chelmsford, Witham, Braintree, South Woodham Ferrers, Billericay, and surrounding areas, brings over two decades of experience to help you transform your home. This comprehensive guide explores various types of house extensions suitable for Essex homes, along with important considerations for homeowners embarking on extension projects.
Types of House Extensions in Essex
Single Storey Extensions
Single storey extensions remain one of the most popular choices for Essex homeowners. Construction Inc specialises in creating versatile spaces that can be used for:
Larger kitchens or open-plan kitchen-diners
Additional living rooms or family spaces
Home offices or study areas
Sunrooms or garden rooms
Key benefits:
Often fall under permitted development rights, potentially avoiding the need for planning permission
Can significantly increase ground floor living space
Generally more cost-effective than multi-storey extensions
Opportunity to improve connection with the garden through large windows or bi-fold doors
Double Storey Extensions
For those needing substantial additional space, Construction Inc offers comprehensive double storey extensions that can provide:
Extra bedrooms and bathrooms
Enlarged living areas on both floors
Potential for master suites or guest accommodations
Key benefits:
Maximises space gain for the footprint used
Often more cost-effective per square metre than single storey extensions
Can dramatically transform the layout and functionality of a home
Side Return Extensions
Particularly popular in Victorian and Edwardian terraced houses common in Essex towns, side return extensions utilise the narrow alley space beside the property. Construction Inc excels at:
Widening and brightening kitchen spaces
Creating open-plan living areas
Adding utility rooms or downstairs bathrooms to provide extra living space for your growing family
Key benefits:
Makes use of often underutilised space
Can significantly improve the flow and light in terraced properties
Usually doesn't require sacrificing garden space
Wrap-Around Extensions
Combining rear and side extensions, wrap-around extensions offer a comprehensive solution for expanding ground floor space. Construction Inc specialises in these extensions, ideal for:
Creating large, open-plan living spaces
Maximising the potential of corner plots
Transforming the entire ground floor layout
Key benefits:
Provides a significant increase in living space
Offers flexibility in design and use of space
Can create a striking architectural feature
Conservatories and Orangeries
While not traditional extensions, conservatories and orangeries remain popular in Essex for adding light-filled spaces. Construction Inc offers modern designs that blur the line between these structures and full extensions:
Conservatories: Primarily glass structures, ideal for enjoying garden views
Orangeries: More substantial structures with a mix of solid walls and large windows
Key benefits:
Can often be built under permitted development rights
Adds a bright, versatile living space
Bridges the gap between indoor and outdoor living
Loft Conversions
While not strictly an extension, loft conversions are a popular way to add living space in Essex homes without expanding the property's footprint. Construction Inc's carpentry expertise is perfect for creating:
Additional bedrooms or home offices
Master suites with en-suite bathrooms
Hobby rooms or playrooms
Key benefits:
Utilises existing space, often not requiring planning permission
Can add significant value to a property
Doesn't reduce garden or outdoor space
Basement Extensions
Less common but gaining popularity in Essex, especially in areas with high property values, Construction Inc can help you:
Create additional living space without altering the external appearance
Provide space for home cinemas, gyms, or additional bedrooms
Key benefits:
Maximises property potential in areas where outward expansion is limited
Can significantly increase property value in prime locations
Front Porch Extensions
A smaller but impactful extension option, Construction Inc can help you utilise unused space to create extra living space:
Enhances kerb appeal and provides a welcoming entrance
Offers additional storage space
Improves home security and energy efficiency
Key benefits:
Often falls under permitted development rights
Can be a cost-effective way to add character and functionality
Planning and Regulations in Essex
When considering a house extension in Essex, it's crucial to be aware of local planning regulations. Construction Inc's experienced team can guide you through this process:
Permitted Development Rights: Many smaller extensions may not require full planning permission, but always check with your local authority.
Conservation Areas: Parts of Essex, including areas in Colchester, Chelmsford, and Saffron Walden, have stricter regulations for extensions.

House Extension Cost Calculator - Costs per square meter
If you're considering extending your home in Essex, one of the first questions you'll likely have is "How much will it cost?". While exact costs can vary significantly based on the specifics of your project, Construction Inc provides this guide with typical cost ranges to help you budget for your Essex house extension.
Average Extension Costs in Essex
Based on recent data and quotes from Essex builders, including Construction Inc, here are the average costs you can expect for different types of extensions in Essex:
Single storey extension: £2,000 - £3,000 per m²
Two storey extension: £2,500 - £3,500 per m²
Loft conversion: £1,500 - £2,500 per m²

So for example, a typical 20m² single storey kitchen extension in Essex would likely cost between £40,000 - £60,000 for the build.
Factors Affecting Extension Costs in Essex
Several factors can impact the cost of your extension in Essex:
Location within Essex - Costs tend to be higher in more affluent areas like Brentwood or Epping compared to other parts of the county.
Specification level - Basic, mid-range or high-end finishes and fittings.
Groundworks required - Sloping sites or poor soil conditions can increase foundation costs.
Design complexity - Unusual shapes or features add to costs.
Access - Difficult access may require specialist equipment, increasing costs.
Planning requirements - Some areas may have stricter planning rules requiring costlier materials.
Breaking Down the Costs
To give you a clearer picture of where the money goes, here's a rough breakdown of costs for a typical Essex house extension:
Building works (labour and materials): 50-60% of the total cost from start to finish.
Windows and doors: 10-15%

Plumbing and heating: 5-10%

By carefully planning your extension and making smart choices on design and materials, Construction Inc can help you create a beautiful new space that adds value to your Essex home without breaking the bank.
What is Planning Permission & Is It Required?
Planning permission is official approval from your local planning authority to carry out building work or change the use of land or buildings. It's designed to control development and protect the environment. Whether you need planning permission depends on the type and scale of work you want to do. Construction Inc's experienced team can help guide you through this process.
When is Planning Permission Required?
Generally, you need planning permission for:
Building a new house
Making major changes to an existing house (large extensions, major renovations)
Changing the use of a building (e.g. from a shop to a home)
Dividing a property into separate units
Major landscaping works that can transform your home into a dream house
Permitted Development Rights
Some smaller projects don't need planning permission if they fall under "permitted development rights". This allows homeowners to make certain types of minor changes without applying for permission. Construction Inc can advise on projects that often fall under these rights, such as:
Small extensions (within specific size limits)
Loft conversions
Adding a conservatory
Installing solar panels
Building a shed or garage (within size limits)
However, permitted development rights can be restricted in conservation areas, for listed buildings, or removed by the local authority. Construction Inc's team stays up-to-date with local regulations to ensure compliance.
How to Check if You Need Permission
Construction Inc recommends:
Checking the Planning Portal website, which has interactive guides
Contacting your local planning authority for advice
Applying for a Lawful Development Certificate to get formal confirmation
The Planning Application Process
If you do need permission, Construction Inc can assist with:
Preparing detailed plans and supporting documents
Submitting your application to the local planning authority
Paying the required fee
Navigating the consultation process with neighbours and other relevant parties
A decision is usually made within 8-13 weeks, from start to finish.
Factors Considered in Planning Decisions
Local authorities base decisions on:
Local and national planning policies
The size, layout, and appearance of the proposed development
Impact on the surrounding area (e.g. traffic, noise, privacy)
Environmental considerations
Construction Inc's expertise ensures your application addresses these factors effectively.
What Happens if Permission is Refused?
If permission is refused, Construction Inc can help you:
Modify your plans and resubmit
Appeal the decision to the Planning Inspectorate
Consider alternative options for your project
Building Without Permission
Building without required permission is risky. The local authority can issue an enforcement notice requiring you to undo the work. In some cases, you may be able to apply for retrospective permission. Construction Inc always recommends obtaining necessary permissions before starting work.
Special Considerations
Construction Inc has experience with special cases such as:
Listed Buildings: Almost any alterations require Listed Building Consent
Conservation Areas: Stricter rules apply to preserve character
Green Belt: Development is tightly controlled
While the planning system can seem complex, its purpose is to ensure development is appropriate and sustainable. For any significant building work or changes to property use, it's always best to check with your local planning authority first. When in doubt, seek professional advice from Construction Inc's planning experts. Remember, planning rules can change, so always check the latest guidance from official sources like the Planning Portal or your local authority website.
How do I comply with building regulations for extensions?
Complying with building extension regulations is essential to the success of your home extension project. These regulations encompass a wide range of safety and quality standards that must be adhered to during construction. From structural integrity to fire safety and accessibility, building control officers will oversee the project to ensure compliance. Construction Inc's team is well-versed in these regulations and can help you navigate them effectively.
Familiarising yourself with these regulations before beginning construction can save you time and money. Non-compliance can result in severe penalties and costly modifications, making it imperative to follow the stipulated guidelines. Construction Inc's expertise ensures that all aspects of your project meet the necessary standards from the outset.
How Much Can You Extend A House?
The extent to which you can extend your house depends on various factors, including local zoning laws, property boundaries, and existing structures. Permitted development rights may allow for certain extensions without the need for full planning permission. However, larger or more complex projects may require detailed applications and approvals, especially if you're aiming to transform your home.
Construction Inc offers initial site surveys to help determine the feasible scope of your extension. Our experienced extension builders in Essex can provide valuable insights into what is possible and permissible for your particular property.
Permitted Development Vs. Planning Permission - What's the Difference?
Understanding the difference between permitted development and planning permission is key to executing a successful extension project. Construction Inc can guide you through these distinctions:
Permitted development rights allow homeowners to carry out specific types of extensions without the need for formal planning permission. These rights are subject to conditions and limitations, often suitable for minor home improvements.
On the other hand, significant projects require planning permission, entailing a more rigorous approval process.
Knowing which category your proposed extension falls into can save you time and avoid future complications. Construction Inc's expertise ensures you take the right approach for your specific project.
Building an Extension under Permitted Development Rights:
Building an extension under permitted development rights offers a streamlined approach to adding extra space to your home. These rights enable homeowners to undertake specific types of extensions without the need for detailed planning permission. Common projects under these rights include single storey extensions and certain loft conversions.
However, it's vital to adhere to the conditions and limitations associated with permitted development. Failure to comply can result in enforcement actions. Construction Inc's team is well-versed in these regulations and can ensure your project remains within the permitted development guidelines, making it essential to consult with us before commencing work.
How much can I extend my house without planning?
The amount you can extend your house without planning depends largely on the permitted development regulations in your area. Generally, you can extend a detached house by up to 8 metres and a semi-detached or terraced house by up to 6 metres under these rights. Other limitations may apply, such as the height and overall volume of the proposed extension.
Construction Inc advises consulting with our experienced team or a local planning authority to understand the specific criteria that apply to your property. This ensures that your project complies with existing regulations and avoids potential issues down the line.
Single Storey Extensions under Permitted Development Rights:
Single storey extensions under permitted development rights offer an effective way to enhance your living space without the need for planning permission. Construction Inc specialises in these types of extensions, which typically cover rear extensions that do not exceed 4 metres in height. For detached houses, the extension can extend up to 8 metres from the original rear wall, while for attached houses, the limit is usually 6 metres.
It's crucial to adhere to building regulations to ensure the new addition is safe and compliant. Construction Inc's expertise ensures that your extension meets all necessary standards. This option is ideal for quick, straightforward expansions that significantly enhance the functionality of your home.
Single Storey Extension Limitations under Permitted Development Rights:
While single storey extensions under permitted development rights offer flexibility, they do come with limitations. Construction Inc will help you navigate these restrictions, which include:
Extensions must not cover more than half the land surrounding the original house.
The height restrictions mean you cannot build higher than 4 metres.
Extensions must be single storey and must not extend beyond the principal elevation of the house.
Violation of these limitations can result in enforcement actions, making it essential to fully understand the permitted development criteria. Working closely with Construction Inc ensures compliance and a hassle-free extension process.
Double Storey Extensions under Permitted Development Rights:
Double storey extensions under permitted development rights allow for considerable enhancement of your living space. Construction Inc can help you design and build these extensions, which can add valuable square footage to both the ground and first floors of your home, providing additional rooms and functionality.
However, these extensions are subject to stringent height and distance regulations. Typically, they cannot be within 7 metres of the rear boundary. Compliance with building regulations and proper planning is essential to ensure the extension is safe and structurally sound. Construction Inc's expertise in double storey extensions offers enormous potential to transform your property.
Double Storey Extension Limitations under Permitted Development Rights:
The limitations for double storey extensions under permitted development rights are quite specific and stringent. Construction Inc will ensure your extension meets these criteria:
The height of the extension must not exceed the existing roof height.
The eaves must align with the original eaves of the house.
These extensions must not be within 7 metres of the rear boundary to ensure privacy for neighbouring properties.
The materials used should be similar in appearance to the existing house.
Adhering to these limitations helps streamline the project approval and ensures that your extension is both compliant and harmonious with the existing structure. Construction Inc's attention to detail guarantees that all these requirements are met.

House Extension FAQ: 20 Common Questions Answered by Construction Inc
Do I need planning permission for my house extension?
Not always. Many smaller extensions fall under 'permitted development rights' and don't require planning permission. However, larger extensions, those in conservation areas, or on listed buildings typically do. Construction Inc can help you check with your local planning authority or use the Planning Portal website to determine if you need permission for your specific project, ensuring your dream house meets all regulations.
How much does a house extension typically cost?
Costs vary widely depending on size, location, and specification. As a rough guide:
Single storey extension: £2,000 - £3,000 per m²
Two storey extension: £2,500 - £3,500 per m²
Loft conversion: £1,500 - £2,000 per m²
Construction Inc always recommends getting a detailed quote for your specific project. We offer free, no-obligation quotes to help you start your planning.
How long does a house extension take to complete?
Timelines can vary, but typical durations with Construction Inc are:
Single storey extension: 3-4 months
Two storey extension: 4-6 months
Loft conversion: 6-8 weeks
These timelines include planning and construction but can be longer if there are complications or delays. We'll provide a detailed timeline for your specific project.
Will an extension add value to my home?
Generally, yes. A well-designed extension by Construction Inc can significantly increase your property's value. However, we advise being cautious not to over-develop for your area, as there's usually a ceiling price for each street or neighbourhood.
Can I live in my house during the extension work?
In most cases, yes, although it can be disruptive. Construction Inc will discuss this with you to understand the impact and consider alternative arrangements for particularly noisy or dusty phases of work.
Do I need an architect for my extension?
While not always necessary, an architect can be invaluable for design ideas, ensuring the extension complements your existing home, and navigating planning processes. For simpler extensions, Construction Inc's architectural technicians or experienced builders might suffice. We can advise on the best approach for your specific project.
What's the difference between a conservatory and an orangery?
Conservatories typically have glass roofs and walls, while orangeries have more solid structures with large windows and a partially glazed roof. Orangeries tend to be more expensive but offer better temperature control and a more permanent feel. Construction Inc can help you decide which option best suits your needs and budget.
Can I build over my property boundary?
Generally, no. You must build within your own property boundaries, whether you're adding extra living space or remodelling existing structures. If you're considering building close to or on a boundary, Construction Inc will ensure you comply with the Party Wall Act and potentially get your neighbour's agreement.
How can I ensure my extension blends with my existing house?
Construction Inc considers matching materials, roof pitch, and window styles to your existing house. Our team can help ensure a cohesive design. Sometimes, a contrasting modern extension can work well with an older property if designed thoughtfully. We'll work with you to achieve the look you desire.
What's the best way to heat my new extension?
Options include extending your existing central heating system, installing underfloor heating, or using a separate system like electric radiators. Construction Inc will advise on the best choice depending on your extension's size, use, and your home's current heating system.
Do I need to update my home insurance when I extend?
Yes. Construction Inc recommends informing your insurer about the extension both during construction (as this changes the risk profile of your property) and after completion, as it will increase the rebuild cost of your home.
Can I do a loft conversion if I have a trussed roof?
Yes, but it's more complex and expensive than converting a traditional rafter roof. Trussed roofs will need additional structural work to create usable space, which should be designed by a structural engineer. Construction Inc's team has experience in transforming trussed roof spaces into functional living areas.
What's the minimum ceiling height for a loft conversion?
Building regulations require a minimum height of 2.2m from the floor to the highest point. If your loft doesn't meet this, Construction Inc can explore options such as lowering ceilings in the rooms below or raising the roof, both of which add complexity and cost but may be worthwhile for the extra space.
Can I add a kitchen or bathroom to my extension?
Yes, kitchens and bathrooms are popular additions to extensions. Construction Inc ensures proper planning for ventilation, plumbing, and electrical needs. We'll make sure your new rooms comply with all necessary building regulations.
How do I choose a reliable builder?
While we hope you'll choose Construction Inc, we always recommend getting recommendations from friends or family, checking online reviews, and asking for references from previous clients. Ensure they're properly insured and consider using members of trade associations. Always get at least three detailed quotes for comparison.
Should I move out during the extension work?
It's not usually necessary, but it can speed up the process and reduce stress. Construction Inc will discuss with you the extent of the work, how it will affect your daily life, and whether you have young children or work from home to help you make the best decision.
What's the best time of year to start an extension project?
Spring or summer is often preferred for better weather, but Construction Inc is busy year-round. Winter builds can work well with proper planning, and you might get better rates. We'll help you choose a time that works best for your specific project and circumstances.
How can I make my extension more energy efficient?
Construction Inc uses high-quality insulation, energy-efficient windows and doors, and can advise on technologies like solar panels or heat pumps. An energy-efficient extension can help reduce your overall energy bills. We stay up-to-date with the latest energy-saving technologies and building practices.
Do I need to notify my neighbours about my extension plans?
It's not legally required unless you're building on or near a shared boundary (in which case the Party Wall Act applies). However, Construction Inc always recommends informing neighbours about significant work that might affect them. We can help facilitate these conversations if needed.
Can I manage the extension project myself to save money?
While possible, it's challenging without experience. You'd need to coordinate various tradespeople, ensure compliance with regulations, and manage the budget and timeline. Construction Inc offers full project management services, which for most people is worth the cost for a smoother process and potentially better results. Our expertise can often save you money in the long run by avoiding costly mistakes or delays.
At Construction Inc, we're committed to making your house extension project as smooth and stress-free as possible. Our team of experts is ready to guide you through every step of the process, from initial planning to final completion.
