Bungalow and upward extensions in Blyth

Covering Blyth

We work in Blyth (NE24) and the places around it, including Bedlington, Ashington and Cramlington.

Because Northumberland covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

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 an upward extension?

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.

How is an upward extension approved in Blyth?

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 Blyth homeowners check first?

The staircase takes space from the ground floor plan.
Neighbours’ light and privacy are the main planning tests.
