Loft conversions

Many loft conversions on houses are permitted development, within limits on the extra volume, where dormers can go and the materials used. A dormer on the roof slope facing the road is not permitted development.

In a conservation area, roof extensions are not permitted development, so they need a planning application.

Flats have no householder permitted development rights, so a loft in a flat needs a full planning application.

Where a project is permitted development, a Lawful Development Certificate from the council confirms it. It’s optional, but it gives certainty and is often asked for when you sell.

An informed view of what’s likely, not a promise. The decision always rests with the council.

1. 01

   Fire safety. A new floor changes how you would get out in a fire. Building Regulations usually call for a protected escape route down through the house.

2. 02

   The staircase. Finding room for a new stair, with enough headroom, often decides the whole layout.

3. 03

   A structural engineer. Usually needed for steel beams, new openings in load-bearing walls and foundations. Their calculations go to building control. I bring the engineer in and manage their work for you.

4. 04

   Party walls. On a terrace or semi, the Party Wall etc. Act 1996 may apply if work is on or near a shared wall or boundary, or digs close to a neighbour’s foundations. Notices must go to the neighbours in good time before work starts.

5. 05

   Building Regulations. A separate approval from planning. It covers structure, fire safety, insulation, drainage and ventilation, and most extensions and structural alterations need it. I prepare the technical drawings.

Measured survey, design options, then planning drawings. I prepare and submit the application, and deal with the council. Then the technical drawings for Building Regulations, with the structural engineer and building control coordinated for you.
