Bungalow and upward extensions in Sunderland

Bungalow and upward extensions for homes in Sunderland and the surrounding parts of Tyne and Wear, designed around your house and built by our teams under a single written contract.

Homes in the North East

Housing across the North East ranges from colliery terraces and Tyneside flats to suburban semis and modern estates, each with different options for extending.

What is included in an upward extension in Sunderland?

The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.

  • Structural survey of walls and foundations
  • Design and planning or prior approval application
  • New first-floor structure, walls and roof

How is an upward extension approved in Sunderland?

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 should Sunderland homeowners check first?

  • Some bungalow foundations need strengthening before a storey can be added.
  • The house is exposed while the roof is off, so the sequence is planned tightly.

From first call to completion

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
