Rear Dormer Loft Conversion Drawings in Greenwich

Which postcode districts around Greenwich do we cover for rear dormer work?

Every Greenwich postcode district we draw in, the stock that dominates it and the authority that validates a rear dormer there. Greenwich fees below are the statutory England rates for 2026, not rear dormer estimates.

Which Greenwich neighbourhoods suit a rear dormer best?

Roof pitch, wall build-up and plot depth change every few Greenwich streets, and each one changes what a rear dormer can achieve at that address.

• New Eltham (SE9) — rear dormer work in New Eltham means 1930s semi-detached. New Eltham is 1930s semi-detached. Hip-to-gable plus rear dormer is the standard sequence on these 1930s semis throughout SE9. Greenwich Council decides the New Eltham application, and New Eltham station anchors the New Eltham location plan.
• Greenwich (SE10) — Georgian World Heritage centre defines Greenwich, where georgian terraces, listed buildings set what a rear dormer can do. A dormer on a Georgian roof has to sit behind the parapet line to stand any chance of consent across SE10. Any Greenwich rear dormer is validated by Greenwich Council, with Royal Observatory the usual Greenwich reference point on the site plan.
• Charlton (SE7) — Victorian villas, 1930s semi-detached defines Charlton, where victorian villas, 1930s semi-detached set what a rear dormer can do. Full-width rear dormers on Victorian terraces here are the default across SE7. Any Charlton rear dormer is validated by Greenwich Council, with Charlton House the usual Charlton reference point on the site plan.
• Woolwich (SE18) — rear dormer work in Woolwich means georgian fragments, post-war estates, new-build. Woolwich is Georgian arsenal heritage, riverside regen. A dormer on a Georgian roof has to sit behind the parapet line to stand any chance of consent throughout SE18. Greenwich Council decides the Woolwich application, and Royal Arsenal anchors the Woolwich location plan.
• Eltham (SE9) — 1930s semi-detached, Tudor fragments defines Eltham, where 1930s semi-detached, post-war flats set what a rear dormer can do. Hip-to-gable plus rear dormer is the standard sequence on these 1930s semis across SE9. Any Eltham rear dormer is validated by Greenwich Council, with Eltham Palace the usual Eltham reference point on the site plan.
• Blackheath (Greenwich) (SE3) — a rear dormer in Blackheath (Greenwich) starts from georgian villas, victorian terraces, and Blackheath (Greenwich) reads as Georgian villas around the heath. A dormer on a Georgian roof has to sit behind the parapet line to stand any chance of consent in SE3. Greenwich Council assesses Blackheath (Greenwich) rear dormers against its own Blackheath (Greenwich) character guidance, and the location plan we draw for Blackheath (Greenwich) references Blackheath Common.
• Thamesmead (SE28) — rear dormer work in Thamesmead means post-war estates, new-build. Thamesmead is post-war estate, Brutalist origins, regen. Trussed post-war roofs need a full structural redesign before a dormer throughout SE28. Greenwich Council decides the Thamesmead application, and Thamesmead Town Centre anchors the Thamesmead location plan.

What local planning policy applies to a rear dormer in Greenwich?

Conservation areas covering Greenwich: Greenwich Council runs 20, and Blackheath, Charlton, Eltham Park are the ones Greenwich owners meet most. A rear dormer inside a Greenwich conservation area loses permitted development, so the Greenwich submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Blackheath a rear dormer is judged on the street elevation first.

Greenwich permitted development status: there is no borough-wide direction from Greenwich Council, so a rear dormer at a SE2 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Greenwich sale to argue it later.

Greenwich housing stock: Georgian in Greenwich town centre; Victorian terraces in East Greenwich, Charlton; inter-war semi-detached in Eltham; new-build along the riverside. World Heritage Site status in Greenwich town centre adds heritage weight; outer borough areas (Eltham, Thamesmead) generally permissive. Read that before choosing a rear dormer route in Greenwich — construction, not postcode, sets what is achievable. Greenwich Council charges £548 for a householder application and has 8 weeks to determine it.

What happens if a Greenwich property sits on a boundary?

• Lewisham — the Lewisham boundary runs against Greenwich, so a rear dormer a street from Greenwich is decided by Lewisham Council instead. Lewisham runs 30 conservation areas across SE3 and its neighbours, which is why rear dormers priced for Greenwich are re-checked against Lewisham policy whenever the Greenwich address sits on that edge.
• Bexley — adjoining Greenwich, with 16 conservation areas centred on DA1. A rear dormer on the far side of the Greenwich line is determined by Bexley Council, so the Greenwich quote for rear dormers is checked against Bexley guidance before it is issued.
• Bromley — cross the Greenwich boundary and Bromley Council takes the rear dormer instead, applying 48 conservation areas of its own around BR1. We re-price rear dormers at the Greenwich edge because Bromley policy and Greenwich policy rarely align on rear dormer depth.
• Newham — the Newham boundary runs against Greenwich, so a rear dormer a street from Greenwich is decided by Newham Council instead. Newham runs 10 conservation areas across E6 and its neighbours, which is why rear dormers priced for Greenwich are re-checked against Newham policy whenever the Greenwich address sits on that edge.
