A home extension can be a major investment for your property, and we are here to help you make the most of it. We have a team of experienced and skilled builders that can provide a comprehensive and professional service, from design and planning, to construction and completion.
Our home extension service begins with a consultation. We listen to your ideas and requirements and help you to design the perfect extension for your home. We take into account factors such as the size and layout of your property, your personal style and preferences, and your budget.
Once your extension design is finalized, our extension builders will begin the construction process. We will carefully prepare the site, and construct your extension, using the highest quality materials and the latest building techniques. We will also advise you on any necessary planning permission and building regulations.
In addition to our construction services, we also offer a range of complementary services to help complete your new extension. These include flooring, plastering, and painting, as well as fixtures and fittings. We also provide a clean-up service, to ensure that your home is left clean and tidy once the construction is complete.
Our services are designed to give you a hassle-free and professional solution to your home improvement needs. With our expert team of home extension builders, competitive prices, and commitment to customer service, we are sure you will be happy with your new extended home.

This is the most popular extension. A single-storey rear extension creates an additional room or extends an existing room.
If you need more space upstairs as well, then a double extension can add space to bedrooms or create a new master bedroom with en-suite or a dressing room.
A wrap extension wraps around two sides of your home: the rear and side creating an L-shaped extension giving you more space.
A side-return extension makes use of space between rear rooms and your boundary fence. This type can extend a kitchen, dining room or living room.
Our assessment is a thorough review of your home extension ideas, how your home is constructed and how feasable your plans are.
Planning permission is not required for all extensions, however, if local authority consent is required, we can help you with the best ways to gain approval.
You will have a dedicated project manager who will be your point of contact throughout the project and will coordinate all aspects of the work carried out.

The size of your extension will determine this. The permitted development rules have recently been relaxed, allowing you to construct an extension of up to six metres without obtaining planning approval (or eight metres if your house is detached). Anything higher than this requires planning permission.
The majority of planning permission applications typically take eight weeks. Generally speaking, this is the case unless the proposed project is large or difficult, in which case a judgement must be made within 13 weeks.
List all the features you want in your extension, such as an extra bedroom with an en suite, a new kitchen, a larger bathroom, and more storage space.
