Extension Architecture

Ilford has quietly become one of East London's most active areas for home extensions, and the reason comes down to its housing stock. The 1930s semis and Edwardian terraces that dominate IG1 and the surrounding postcodes are close to ideal for rear extensions and loft conversions. Add generous plot sizes and streets that mostly retain permitted development rights, and you have an area where extending makes real sense. If you are weighing up an extension in the borough, the short video below walks through the key considerations, and this guide expands on what actually matters for Ilford homeowners planning their next move. Watch the full overview here: Ilford extension and planning guide Why Ilford Suits Extensions So Well The character of the housing is the starting point. Ilford blends historic Victorian and Edwardian buildings with more modern construction, and that older stock in particular lends itself to sympathetic expansion. 1930s semi detached houses typically offer...

Bexley sits at the outer edge of south east London where the borough starts to feel more like Kent than the city. Generous plots. Detached and semi detached stock that dominates most residential streets. A planning authority in London Borough of Bexley that processes applications methodically and has its own specific expectations around design quality and impact on neighbouring properties. Watch our Bexley architects  project video to see real DA postcode projects from survey through planning to finished build. What the Housing Stock Actually Offers Bexley's residential streets are dominated by interwar semis and detached homes across DA5, DA6, DA7, and DA14. These properties were built with more generous proportions than Victorian terraces. Wider plots. Deeper gardens. Side access that creates real extension options. That physical scope means the same budget achieves more in Bexley than on a tighter inner London plot. A 6 metre rear extension on a DA5 semi leaves a workable ga...

Most extension projects in Hounslow run into trouble before an architect has drawn a single line. The mistake happens earlier. An assumption is made about permitted development. A builder is called before the planning position is confirmed. A design brief gets fixed before anyone has checked what the specific address actually allows. Watch our Hounslow architects to see real TW projects from first survey through planning to finished build. The Permitted Development Assumption This is the mistake that comes up most consistently across TW3, TW4, TW5, TW7, and TW8. Hounslow has conservation areas in parts of Isleworth, Brentford, and Chiswick borders. It has Article 4 Directions on specific streets that remove permitted development rights independently of conservation area status. And it has a varied housing stock where what applies to one property on a street does not automatically apply to the next. The standard permitted development limits for single storey rear extensions are 3 me...

  Most bexley architects will tell you the borough has a genuine advantage when it comes to extending a house. Full permitted development rights survive on plenty of streets, letting a lot of projects skip a formal planning application entirely. Old Bexley doesn't quite follow that pattern. Why DA5 Feels Different From the Rest of the Borough Bexleyheath and Barnehurst, covered by DA6 and DA7, are dominated by 1930s semis with fairly consistent plot depths and roof pitches. Old Bexley, in DA5, has a different character entirely, older Georgian and Victorian properties sitting within a conservation area that Bexley Council treats with more scrutiny than the newer suburban streets nearby. That difference matters because generic advice about Bexley extensions, the kind that talks about the borough's relatively relaxed permitted development picture, doesn't automatically apply here. Old Bexley genuinely plays by a different set of assumptions. What Conservation Area Status ...

A loft conversion sounds straightforward until you start asking the right questions. How much headroom do you actually have. What roof structure are you working with. Does your street have permitted development rights or has an Article 4 Direction removed them. Hounslow has a varied housing stock across TW3, TW4, TW5, TW7, and TW8, and the answers to these questions vary significantly depending on exactly where you live. Watch our Hounslow architects   project video to see real TW loft projects from first survey through to finished room. The Roof Structure Question That Decides Everything Before any drawings, before any quotes, before any planning conversation, someone needs to go into your loft with a tape measure. Two things matter most. Head height at the ridge and roof structure type. Most properties built before the 1960s across Hounslow have traditional cut roofs. These have individual rafters and are well suited to conversion. Properties built after the 1970s increa...

  Two houses. Same SW19 postcode. Same street. One extends without planning permission. The other gets enforcement action for doing the same thing. That is not a hypothetical. It happens in Wimbledon because Article 4 Directions do not follow postcode boundaries. They follow street boundaries. Sometimes they follow one side of a street. The family at number 14 can extend under permitted development. The family at number 15 cannot. Watch our Wimbledon architects project video to see how Extension Architecture has navigated this across 45 completed SW19 and SW20 projects. The Street Level Rule That Changes Everything Article 4 Directions in Wimbledon remove permitted development rights on specific streets. Not specific postcodes. Not specific conservation areas. Specific streets. A rear extension up to 3 metres deep on a terraced house is automatic in most of London. On an Article 4 street in SW19 it needs a full planning application to Merton Council. The 8 week decision timeline a...
