Home Extensions FAQ Section
Do I need planning permission for a home extension?
Not all home extensions require planning permission. Some projects fall under permitted development rights, depending on the size and type of extension. We can advise you on whether your North London extension project will need planning approval before work begins.
How much does a home extension cost in North London?
The cost of a home extension depends on the size, design, materials, and specification of the project. Factors such as structural work, kitchen installations, and finishes can also affect the final cost. We provide free quotations tailored to your requirements and budget.
How long does a home extension take to complete?
Most home extension projects take between 8–16 weeks depending on the complexity and size of the build. We provide a clear project timeline before work starts and keep clients updated throughout the process.
What types of home extensions do you build?
We specialise in a range of home extensions including rear extensions, side return extensions, wraparound extensions, kitchen extensions, and double-storey extensions across North London and NW10.
Can I live in my home during the extension work?
In many cases, clients are able to remain in their property while the extension is being built. This depends on the scale of the project and the areas being renovated. We always work to minimise disruption where possible.
Why should I choose a home extension instead of moving?
A home extension can increase living space and add value to your property without the stress and expense of moving house. It allows you to improve your existing home while staying in the area you already know and enjoy.
