Do you need planning permission for house extensions?
In some cases, extensions fall under permitted development rights. We can advise you on this and ensure you understand what to do should planning applications be necessary.
Can you match the extension to my existing property?
Absolutely. We ensure materials, brickwork, and design details blend seamlessly with your home for a natural, cohesive look. Alternatively, we’re happy to create something unique that stands out as a statement feature against the backdrop of your home.
How long does a typical extension take?
Timelines vary based on size and complexity, but most single-storey extensions take around 10–14 weeks, with double-storey extensions taking slightly longer.
Will I need to move out during the work?
You can usually stay in your home during construction. We’ll plan carefully to minimise disruption wherever possible.
Can you help design my extension?
Yes, we work closely with trusted designers or can recommend partners to bring your ideas to life.
