Loft conversions in Woolwich: dormer, rooflight and hip-to-gable. Structure, stairs, insulation and Building Control handled. Fixed written quotes.
Rear dormers are usually permitted development, within volume limits. A dormer on the front elevation almost always needs permission. We will tell you which side of that line your design is before it is drawn up.
About 2.2m from the ceiling joists to the ridge to work with. Under that, a conversion means lowering ceilings below or raising the roof - both possible, both a different order of cost.
Sometimes you lose part of one, and that is the trade-off worth understanding early. On many Woolwich terraces the stairs can rise over the existing flight and take very little. It depends on the layout, and we will show you.
A typical rear dormer is around six to eight weeks on site, after the design and approvals. Much of the work is done from scaffolding outside, so the house can usually stay lived in until the stairs go in.
Several parts of Woolwich are, including around the Royal Arsenal and Woolwich Common. The council can confirm it for a specific address, and it matters because it removes some permitted development rights for roof changes.
A loft conversion is usually the cheapest bedroom you will ever add, because the roof and the walls already exist. What decides whether it is possible is head height, and that is a fifteen-minute check rather than a survey, worth doing before anybody gets attached to the idea.
Woolwich terraces and semis often have more usable loft space than their owners expect, especially the Victorian houses around Plumstead with a good roof pitch. Where a house sits in one of the local conservation areas, though, even a rear dormer needs planning permission, so that is checked at the very start.
Around 2.2m at the ridge is the working minimum for most conversions. We measure before you spend anything on drawings.
A rooflight conversion is cheaper and keeps the roofline; a dormer buys usable floor area and head height. The roof pitch usually decides which is sensible.
Where the stairs land is the hardest part of most loft conversions and it costs a bedroom below if it is planned badly.
A loft bedroom changes the fire escape route for the whole house. Doors, alarms and the stair enclosure all form part of the sign-off.
Permitted development rights for roof extensions do not apply in conservation areas, so the address is checked before a dormer is designed.
A dormer on a terrace or semi usually involves the party wall, so the notice is served early to keep the programme on time.
