Frequently Asked Questions

Is extending your home more affordable than moving?
In most cases, extending is cheaper than moving, as it avoids costs like stamp duty and legal fees. Only major projects, such as basement excavations, may cost more.

A double-storey extension adds significant space, often more than a single-storey option, increasing your home’s value. Its worth depends not just on added room, but on how you utilise the extra space effectively.

A two-storey extension usually takes around 20–24 weeks in total, with the construction phase itself lasting approximately 14–16 weeks, due to the project’s increased complexity and scale.
The 45-degree rule ensures your extension doesn’t block a neighbour’s light. From the centre of their nearest ground-floor window, your extension should not extend beyond a 45-degree angle when viewed from above.
A two-storey extension typically costs between £45,000 and £60,000, depending on size and specifications. A small side extension starts around £30,000 for materials, rising to approximately £33,000 if a bathroom is included.
