Learn more →House extensions in Greenwich
Greenwich has Georgian and Victorian terraces in West Greenwich and the Ashburnham Triangle, Victorian houses towards Maze Hill and Westcombe Park, and Edwardian terraces in East Greenwich. Rear and side-return kitchen extensions are the common Greenwich projects; in the Ashburnham Triangle and West Greenwich the design must work with the conservation area.
As a guide, a well-built single-storey rear or side-return extension in Greenwich costs around £2,500–£4,000 per m² including structure, glazing and finishes, so a typical 25–30 m² kitchen extension lands between £75,000 and £120,000. Our house extension cost guide explains what moves the price. West Greenwich, Ashburnham Triangle and Westcombe Park are conservation areas where Greenwich Council expects rear-only roof changes and traditional materials. We confirm permitted development rights at the first visit and handle any application to Greenwich Council through our in-house design team.
Loft conversions in Greenwich
Greenwich lofts are mostly rear dormers and mansards on the Victorian terraces; the Georgian houses have limited roof space, so a survey comes first.
In London a Velux conversion costs £25,000–£45,000, a dormer loft with a bedroom and en-suite £45,000–£75,000 and a mansard £60,000–£100,000+; our loft conversion cost guide sets out what is included. We survey the roof structure, head height and stair position before we quote a Greenwich loft, so the figure reflects the actual roof rather than an assumption.
Renovations and refurbishment in Greenwich
Greenwich renovations are often period restorations of Georgian and Victorian houses combined with modern kitchens and bathrooms. Typical Greenwich refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. Our Victorian terrace renovation cost guide gives realistic budgets, and every Greenwich project runs on a JCT contract with a written specification and our 10-year workmanship warranty.
