Expert Guidance Through Planning & Building Regulations
We Make Extension Planning Permission Straightforward
NAVIGATING THE PLANNING PROCESS
Dreaming of more space but dreading the planning process? You're not alone. Many Chelmsford homeowners feel overwhelmed by extension planning permission requirements, often delaying their project due to confusion about paperwork and regulations. At Construction Inc Limited, we understand this frustration, which is why we handle the entire planning journey for you. Since 2022, our family-run team has guided countless Essex homeowners through the maze of extension planning regulations, turning potentially stressful situations into straightforward experiences. Our approach combines local knowledge with technical expertise, ensuring your application has the best chance of approval.
We begin by listening to your vision, then connect you with our trusted architect who'll create detailed architectural drawings tailored to both your needs and local planning constraints. These plans become the foundation of your extension planning permission application, which we'll prepare and submit to Chelmsford City Council on your behalf. Our established relationship with the local authority means we understand what they're looking for and how to present your project in the most favourable light. If you choose to proceed with our building services after planning approval, we'll subtract the planning and design costs (up to £1,200) from your final invoice.

Understanding Planning Permission Requirements
WHEN YOU NEED PERMISSION AND WHEN YOU DON'T
Navigating extension planning permission begins with understanding whether your project requires full planning approval or falls under 'Permitted Development' rights. In Chelmsford, many smaller extensions can proceed without formal permission, provided they meet specific criteria regarding size, height, and proximity to boundaries. Typically, single-storey rear extensions can extend up to 4m from the original house for detached properties (3m for semi-detached or terraced homes) without requiring permission. Similarly, side extensions may be permitted if they're single-storey, less than 4m in height, and don't exceed half the width of the original house. However, these rights are restricted if your property is listed, in a conservation area, or has already been extended.
Even when your project seems to fall within Permitted Development, we recommend obtaining a Certificate of Lawful Development from Chelmsford Council. This document provides legal confirmation that your extension doesn't require planning permission—valuable evidence should you sell your property in the future. For larger projects requiring full extension planning permission, the process involves submitting detailed architectural drawings, design statements, and potentially additional assessments depending on your location and project scope. Our experience with house extension regulations in Chelmsford means we can advise you on the most appropriate route for your specific circumstances, saving you time and potential disappointment. Understanding these requirements early helps set realistic expectations for your project timeline—typically 8-10 weeks for planning decisions in Chelmsford, with construction only commencing after approval.

The Planning Application Process Explained
PREPARING AND SUBMITTING YOUR APPLICATION
The application process for extension planning permission involves several critical steps, beginning with professional architectural drawings that precisely detail your proposed extension. These drawings must include floor plans, elevations, site location plans, and often 3D visualisations to help planning officers understand how your extension will look in context. Our architect creates these detailed plans while considering both your vision and compliance with house extension regulations. They'll highlight important elements like materials, dimensions, and the relationship to neighbouring properties—all crucial factors in planning decisions. Once your plans are finalised, we prepare a comprehensive planning statement explaining how your extension aligns with local policies and addressing potential concerns before they're raised.
We handle the submission through the government's planning portal, ensuring all documentation is complete and accurate. This includes the standard application forms, ownership certificates, detailed drawings, planning statements, and payment of the application fee (currently £206 for householder applications in Chelmsford). After submission, your application undergoes an 8-week determination period during which the local authority will consult with neighbours and other relevant parties. We monitor the application throughout this period, promptly addressing any queries or concerns raised by the planning officer. Our proactive approach to planning a house extension often helps secure approvals without modifications, saving you valuable time. If your application faces challenges, we can advise on design amendments or whether to appeal decisions.

Building Regulations Approval For Your Extension
ENSURING COMPLIANCE BEYOND PLANNING PERMISSION
Extension planning permission is just one part of the regulatory requirements for your project. Equally important is compliance with building regulations—the technical standards ensuring your extension is structurally sound, energy-efficient, and safe. Unlike planning permission, which focuses on how your extension looks and affects the surroundings, building regulations concern the construction itself—from foundations and structural integrity to insulation, fire safety, ventilation, and drainage. Even if your extension falls under Permitted Development rights and doesn't require planning permission, it will still need building regulations approval. At Construction Inc Limited, we handle this process alongside your extension planning, preparing detailed technical drawings and specifications that demonstrate compliance with all relevant standards.
The building regulations application process involves submitting either a Full Plans application, where detailed technical drawings are approved before work begins, or a Building Notice, which allows work to start sooner but carries more risk of remedial work if inspections identify issues. For extensions, we typically recommend the Full Plans route for certainty before breaking ground. We prepare these technical submissions separately from your planning a house extension application, as they require different levels of detail and are assessed by different departments within the local authority. Throughout construction, building control officers will make several site inspections at key stages—from foundation excavation through to completion. Our experienced team anticipates these inspections, ensuring work proceeds smoothly and compliance is demonstrated at every stage.

Working With Chelmsford Council Planning Department
NAVIGATING LOCAL POLICIES AND REQUIREMENTS
Successfully navigating extension planning permission in Chelmsford requires understanding the specific policies and priorities of the local planning department. Chelmsford City Council operates under its Local Plan, which outlines policies on design, sustainability, parking, and impact on neighbours—all factors considered when assessing extension applications. Our team stays current with these local policies, understanding their practical application to residential extensions. This local knowledge proves invaluable when preparing your extension planning application, allowing us to anticipate potential objections and address them proactively. We've established professional relationships with planning officers through years of submitting quality applications, which helps facilitate constructive discussions about your project when needed.
Pre-application consultations with the local authority can be beneficial for more complex extensions or properties in sensitive areas. These paid consultations provide initial feedback before submitting a formal application, potentially saving time and money by identifying issues early. We can arrange and attend these meetings on your behalf, presenting your architectural drawings and explaining your vision to planning officers. Throughout the application process, we maintain regular communication with the planning department, monitoring your application's progress and responding promptly to any queries. If modifications are requested, we'll explain these clearly and discuss practical solutions that maintain your project's integrity while satisfying planning requirements. This collaborative approach to plan house extension projects helps achieve positive outcomes even for challenging applications.
