Frequently Asked Questions About House Extensions
Do I need planning permission for an extension?
This completely depends on the size and type of extension. Many single-storey rear additions and small porches may fall under permitted development, but larger or taller works — especially double-storey extensions — often need planning permission. We carry out a free permitted development check during the site survey and will advise whether a full planning application is necessary.
How long will my extension project take?
Timescales vary by project size and complexity. Typical single-storey extensions often take around 6–12 weeks on site; double-storey projects generally take longer. The itemised quote we provide after the survey includes an indicative programme tailored to your extension project and site conditions.
How much will my extension cost?
Costs depend on size, specification, structural work and finishes. We provide free, itemised estimates after a site survey so you receive realistic extension costs for your property. Bring any brief or budget range to the survey and we’ll show costed options and value-focused ideas.
Will building regulations apply?
Yes — building regulations apply to most structural, thermal and safety aspects of an extension. We handle building control liaison, submit required documents, and supply structural calculations and certification where needed to ensure compliance.
Can you check if my project qualifies under permitted development?
We assess permitted development rights as part of the survey and will advise whether planning permission is necessary. Where a planning application is required, we can prepare and submit it on your behalf to simplify the process.
