Frequently asked questions about our Extension projects
- What is the typical timeline for completing an extension project?
The duration depends on the size and complexity of the build, but most home extensions take between 8–16 weeks from the start of construction. We provide a detailed schedule before work begins so you always know what to expect.
- Will I need planning permission for my extension?
Most extensions require planning approval unless they fall under permitted development rights. We’ll put you in contact with Building Control and/or a local Architect to assist with the planning application process.
- How can I ensure my extension project stays within budget?
We offer a free, detailed quotation at the start of your project and maintain transparent pricing throughout. Any changes are discussed and agreed before work continues, so there are no surprises.
