Your Local Loft Conversion
Specialists in Lambeth
Buildaway's loft work spans Lambeth and SE11, SE1, SW2, from Lambeth Palace and Kennington Road through to the roofs bordering Lambeth Bridge, with structure and stairs resolved first.
Lambeth roofs divide into two types and the type dictates the cost. Traditional cut roofs open up straightforwardly. Trussed roofs common across SE11 need the structure replaced before there is usable space at all. Buildaway measures from ridge to joist first, then checks the landing can take a compliant staircase. For Lambeth owners near Imperial War Museum or Kennington Park, Buildaway covers the SE11 streets either side of Clapham Road on the same schedule.
Homeowners across Lambeth choose Buildaway for lofts that add real, usable space. Our workmanship, clear pricing, and coordinated management mean a SE11 conversion delivered on programme and signed off to full building control standards.

Frequently Asked Questions
Your questions about loft conversions in Lambeth, answered.
Can any roof be converted?
No, and it is better to know early. Trussed roofs common across SE11 need the structure replaced before there is usable space, which changes the job and the figure. Buildaway identifies the roof type at survey rather than after deposit.
How much headroom do I need for a loft conversion?
As a working rule you want around 2.4 metres from the top of the ceiling joist to the underside of the ridge before adding a dormer. Below roughly 2.2 metres the options narrow considerably. Buildaway measures on the first visit and tells you straight away which category your Lambeth roof falls into.
How long does a loft conversion take?
A dormer conversion on a Lambeth property is typically eight to twelve weeks. A trussed roof needing structural replacement takes longer. Scaffolding, steel lead times and building control inspections sit inside that period and are shown separately on the programme.
Can I have an ensuite in the loft?
Usually yes, provided the waste can reach the existing stack and the floor structure allows it. Buildaway checks the stack route in the Lambeth property before the layout is fixed, because it often decides where the bathroom can sit.
Will I need planning permission in Lambeth?
Many rear dormers fall under permitted development, but properties inside multiple Lambeth conservation areas, listed building consent and Article 4 directions are treated differently and may need a full application. Buildaway confirms the designation with London Borough of Lambeth before design work begins.
