Frequently asked questions
Do I need planning permission?+
Many rear extensions are permitted development. Larger or side-return extensions usually need planning. We coordinate the application.
Can I stay in the house?+
Yes for most of the build — the break-through to the existing house is short, typically 1–2 days.
How long does an extension take?+
A single-storey rear extension typically runs 14–20 weeks on site. Double-storey and wrap-arounds run 20–30 weeks depending on finish.
Do you handle the architect and structural engineer?+
Yes. We can appoint and manage the architect and structural engineer, or work with your own if you already have professionals engaged.
Can you match my existing bricks and roof tiles?+
Yes — we source matching or reclaimed bricks and tiles so the extension reads as part of the original house rather than an obvious bolt-on.
Do you offer bi-fold doors, sliding doors and roof lanterns?+
Yes — aluminium bi-fold and slim-frame sliders, plus GRP, aluminium and timber roof lanterns from major UK suppliers.
