Local knowledge of Sidcup, from first feasibility conversation through to a finished project.
Living and Building in Sidcup
Sidcup is one of Bexley's most established residential areas, with a busy centre, good rail links and a wide range of homes, from Victorian and Edwardian houses to inter-war family houses on generous plots.
As an AEC (Architecture, Engineering and Construction) consultancy, Diagram X looks after the whole project. In Sidcup that commonly means extensions, loft conversions, and careful updating of larger family houses.

Planning in Sidcup
Sidcup contains several conservation areas, including Christ Church, The Green, Halfway Street, The Hollies, Longlands Road, Old Forge Way, The Oval and Willersley/Braundton Avenue. Which one applies, if any, makes a real difference to what you can do.
Old Forge Way is also covered by an Article 4(2) direction, which removes some permitted development rights. We confirm the exact status of each property at the start.

Refurbishing in Sidcup
Sidcup's older houses often have good proportions but outdated services and layouts. Updating them thoughtfully can transform how they work.
A confidently modern result is always the starting assumption. In conservation areas we focus change on the rear and interior, where it is easier to achieve a contemporary result.

Construction in Sidcup
Mature streets and established neighbours call for careful site management. We plan around access and working hours and advise on the notices that may be required.
Coordinated design and structural information help builders price accurately and reduce changes on site.
