It depends on size, spec and structural work — a single-storey extension in Bolton typically starts from the £30,000s, with double-storey and high-spec builds costing more. We visit, talk through exactly what you want, and give you a clear written quote with clear costs and timescales. Quotes are always free.
Many loft conversions fall under permitted development, so full planning permission often isn’t needed — though building regulations always apply. We advise you clearly at the quote stage, recommend trusted architects and structural engineers, and handle building control approvals for you.
Usually, yes — a garage conversion is one of the most cost-effective ways to add living space, turning an underused garage into a bedroom, office or playroom for far less than an extension. Most don’t need planning permission, and it can add real value to your home.
