What to expect during a single-storey rear extension
A clear, practical overview of the stages, site routines and everyday impacts of a single-storey rear extension in…
A loft conversion turns unused roof space into a bedroom, office or extra bathroom without taking any of the garden. Whether it works depends mainly on three things: head height, the roof structure, and where the new staircase can go.
Is your loft suitable?
We measure from the top of the ceiling joists to the underside of the ridge. Many older Northumberland houses with steep slate roofs have generous space; some modern homes with trussed rafters and shallow pitches have far less, though they can often still be converted with a dormer. We also look at the existing joists, because loft floors usually need strengthening.
Types of loft conversion
- Rooflight (Velux-style) conversions – the roof shape stays the same and windows are fitted in the slope. Usually the simplest route where height allows.
- Rear dormers – a box-shaped addition to the rear slope creates full-height floor space.
- Hip-to-gable – on hipped roofs, the sloping end is built up into a vertical gable to make room for the stairs.
- Mansard-style – a larger rebuild of the roof slope, usually needing planning permission.
Stairs and fire safety
The new staircase is often the hardest part of the design. It has to fit on the floor below with adequate headroom without wrecking a bedroom. Building regulations also require a protected escape route – typically fire doors to rooms off the stairway and mains-powered smoke alarms. We plan this at the start.
Planning permission
Many loft conversions are permitted development, within volume limits and with conditions on materials and position. Front dormers, houses in conservation areas, listed buildings and flats need permission. Building regulations approval is always needed.
Keeping it warm and dry
Lofts get hot in summer and cold in winter unless the insulation and ventilation are right. We insulate to current standards and design ventilation so condensation does not build up – particularly important under natural slate roofs.
