Bungalow and upward extensions in Wigan

Covering Wigan

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

What is included in an upward extension in Wigan?

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.

Planning and building rules in Wigan

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 change the price or programme?

The house is exposed while the roof is off, so the sequence is planned tightly.
Neighbours’ light and privacy are the main planning tests.
