Bungalow and upward extensions in Stroud

Covering Stroud

Our coverage around Stroud (GL5) also includes Tetbury (8 miles to the south) and Gloucester.

Homes in the South West

The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.

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.

What will an upward extension cost?

Use these ranges to budget for bungalow and upward extensions; the survey turns them into a fixed price for the agreed specification.

How is an upward extension approved in Stroud?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

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 affect an upward extension?

Some bungalow foundations need strengthening before a storey can be added.
Neighbours’ light and privacy are the main planning tests.
