About a two-storey side extension
A two-storey side extension suits a detached or semi-detached house with a side garden, driveway or garage wide enough to build on. You get a design that sits comfortably on the street, a planning application or permitted development check depending on your nation, structural design, building regulations approval and the build itself. We manage the whole process, and the work is carried out by vetted teams working under S&K.
We cover postcode district NE65 in and around Hadston, along with neighbouring Amble, Pegswood and Ashington.

Planning and building regulations in Hadston
In England, a two-storey side extension always needs householder planning permission, because permitted development only allows single-storey extensions beyond a side wall.

Expect them to look at set-back, roof height, gaps to the boundary and the effect on neighbours.

Design points for Hadston homes
Access and services
Side extensions often cover the only route to the back garden, a gas meter, soil pipes or a drain run. We plan bin and bike access, move meters and pipes where needed and check drains early, because these items affect both cost and layout.
Matching the ridge and roof
A hipped house usually needs a hipped extension roof, and a gabled house a gable. Matching the pitch, tiles, ridge detail and brick bond is what makes a side extension look original rather than added, and councils look closely at it on a front-facing addition.

Can I build a two-storey side extension over my driveway?
