Create the extra space your home needs with a professionally designed and built house extension from Insight Construction Group Ltd. Whether you are planning a larger kitchen, an open-plan living area, an additional bedroom, a home office or a multi-purpose family space, we can manage the entire project from initial ideas through to final decoration.
Our Brighton-based team provides a complete extension building service, coordinating every stage of the work under one roof. This includes groundwork, foundations, brickwork, roofing, plumbing, heating, electrical installations, plastering, flooring, decorating and all other trades required to complete your extension.
With one experienced team managing the project, you will not need to arrange separate contractors or coordinate different trades yourself. We organise the work in the correct order, maintain clear communication and ensure every part of the extension is completed to a consistently high standard.
Every property and every household is different. We take the time to understand how you use your home, what additional space you need and how the extension should connect with the existing building.
The layout, materials, windows, doors and finishes are carefully considered so that the completed extension feels like a natural part of your home. We also pay close attention to natural light, insulation, ventilation and energy efficiency to create a comfortable space that can be enjoyed throughout the year.
We can help with a variety of extension projects, including:
Building an extension involves much more than walls and a roof. It requires several skilled trades working together at the right stages of the project.
Insight Construction Group Ltd manages the entire build, including electricians, plumbers, heating engineers, groundworkers, bricklayers, carpenters, roofers, plasterers, tilers, kitchen fitters, flooring specialists and decorators. We provide one point of contact throughout, making the process simpler and easier to manage.
From preparing the site and installing the foundations to fitting sockets, lighting, radiators, kitchens and bathrooms, we take care of everything needed to deliver a completed extension that is ready to use.
We discuss your ideas, assess the available space and help you develop a practical extension that suits your property, lifestyle and budget.
We can assist with planning applications, building regulations and the drawings or structural calculations required for the project.
Our team prepares the site and completes the excavation, foundations, drainage alterations and other essential groundwork.
We manage the brickwork, blockwork, steel installation, structural openings and all other construction work required to create a strong and compliant extension.
We install the roof, insulation, windows, doors, guttering and external finishes needed to make the extension secure, weather-resistant and energy efficient.
Qualified tradespeople complete all required plumbing and electrical installations, including pipework, radiators, underfloor heating, sockets, lighting, switches and appliance connections.
Where required, we can install kitchens, bathrooms, fitted storage, internal doors, skirting boards and other carpentry or joinery features.
