Bungalow and upward extensions in Bexley

We take on bungalow and upward extensions in Bexley as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Bexley

Bexley is about 13 miles east of London. We also cover Welling (2 miles to the north-west), Dartford and Swanley.

Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What does an upward extension involve?

An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.

  • Structural survey of walls and foundations
  • Roof removal and temporary weather protection
  • Full fit-out of the new rooms

How is an upward extension approved in Bexley?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

In England, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters.

What can change the price or programme?

  • Some bungalow foundations need strengthening before a storey can be added.
  • The staircase takes space from the ground floor plan.

  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
