FAQs

Extension Questions

Do I need planning permission for a house extension?+
Many extensions fall under permitted development rights and do not require planning permission. Single-storey rear extensions up to 4 metres (detached) or 3 metres (semi/terraced) typically do not need planning. We assess permitted development rights at the initial site visit.
How long does a house extension take?+
A single-storey extension typically takes 10–14 weeks from groundworks to completion. Double-storey extensions run 16–22 weeks.
How much does a house extension add to property value?+
In Berkshire, a well-executed single-storey extension typically adds 10–12% to property value. A double-storey extension adds 15–20%.
What is a fixed-price quote?+
Our quotes cover all labour and materials to practical completion. The price is locked at the point of agreement. No hidden costs, no surprises.
Do you manage the planning application?+
Yes. We coordinate with your architect and submit planning applications on your behalf. We can also recommend trusted local planning consultants.
