FAQs

Many extensions can be built under permitted development rights without planning permission, but this depends on factors like the size, location, and your property type. Single-storey rear extensions up to 6 metres for terraced houses or 8 metres for detached houses often fall under permitted development. However, conservation areas, listed buildings, and flats have different rules. We provide guidance on planning requirements during our initial consultation and can recommend planning consultants if needed. Building regulations approval is always required regardless of planning permission status.
Extension timelines vary depending on size and complexity. A single-storey rear extension typically takes 6-8 weeks from start to finish, while double-storey extensions usually require 10-12 weeks. This includes all structural work, roofing, windows, and basic internal finishes. Weather conditions and any unforeseen issues can affect timelines. We provide detailed schedules during the planning phase and keep you updated on progress throughout the project. Our 20 years of experience helps us anticipate potential delays and plan accordingly.
Most homeowners can remain in their property during extension work, though there will be some disruption. We minimise inconvenience by maintaining clean, professional working practices and coordinating noisy work for appropriate times. The connection phase, where we link the extension to your existing house, typically requires the most disruption but we plan this carefully to limit the impact. We'll discuss the specific implications for your project during consultation and work with you to plan around important events or family needs.
Our extension work comes with a comprehensive guarantee covering all structural work, weatherproofing, and finishes. This includes the foundation work, wall construction, roofing, window installation, and all plastering work. The guarantee covers defects in workmanship and ensures any issues are rectified promptly at no cost to you. We stand behind our work with confidence, having built our reputation on quality construction over 20 years. All guarantees are provided in writing upon project completion.
