Extension Architecture

Richmond upon Thames refuses roughly one in five householder applications, which is worse than the national average. That single number explains why choosing a designer here is a different exercise from choosing one in a low constraint borough. If you want a feel for how a scheme is put together before you commit, this walkthrough from top architects Richmond homeowners rely on is a useful starting point. Most people search for the best practice in the area. The more useful question is narrower. Who has read the conservation area appraisal that covers your street, and can they show you a decision notice to prove it. What Makes Richmond Different From Most Boroughs The council designates 72 conservation areas . That is one of the highest concentrations anywhere in the country, and inside those boundaries your permitted development rights shrink or vanish. On top of that sit three constraints that catch people out. A borough wide Article 4 direction on basements , so subterranean ...

  Drive from Between Streets out towards the Fairmile and the houses change completely within about a mile. Modest interwar semis give way to gated detached plots sitting behind hedges, and the planning position shifts just as sharply. Any Cobham architecture practice working here starts with the plot rather than the drawings, because two owners can be neighbours in postcode terms and still be governed by entirely different rules.  Most guides to extending in Cobham talk about the town as one place. It isn't. So here's a more useful map of it. Why KT11 Property Types Decide Your Options Before Policy Does Start with the building rather than the rules. Cobham's stock splits roughly three ways, and each responds differently. Detached houses on generous plots , concentrated around the Fairmile, Oakdene Road and the roads running towards Oxshott. Physical space is rarely the constraint here. Policy usually is, because these are the plots most likely to sit in Green Belt. Olde...

  Most people in Fulham hear the words Article 4 and assume their extension plans are finished. Thats not what happens. What actually happens is more frustrating, because the rules are narrower than the rumours suggest but they land in places nobody expects, and this Fulham extension planning explained breakdown covers where the confusion usually starts. I have watched homeowners abandon perfectly buildable schemes because a neighbour told them something wrong over the fence. I have also watched people spend money on drawings for a basement that was never going to be permitted development. Both mistakes come from the same gap in information. So here is what the borough actually restricts, and what it doesnt. Myth One: Article 4 Means You Cant Extend In Fulham At All This is the version that spreads fastest and its wrong. An Article 4 direction removes specific permitted development rights. It does not remove your right to apply for planning permission. The distinction matters mo...

Fulham has a lot of Victorian terraces and quite a bit of planning complexity. Here are the 5 questions that come up most, answered simply. Do I Need Planning Permission for My Extension? It depends on your street. Some parts of Fulham still have full permitted development rights. But Article 4 Directions remove those rights on many streets across W6, W12, and SW6. Where that applies, even a simple single storey rear extension needs a full planning application. Architects in Fulham check your address against the Article 4 map before any design work starts. It costs nothing to ask, and it changes everything about how your project needs to run. Skipping this step is the single biggest reason projects lose time later, once drawings already exist for a route that was never actually available. A short phone call at the very start avoids that entirely. What Kind of Extension Actually Suits My House? Victorian terraces dominate this area. Most suit a single storey rear extension, a side...

Thinking about extending your home in Wandsworth? Here's what you actually need to know, kept short and simple. Check Article 4 First This is the most important step. Many Wandsworth streets have Article 4 Directions. These remove your normal permitted development rights. So even a small rear extension might need full planning permission. Wandsworth architects check this before any design work starts. It takes a few minutes to confirm against your exact address. Don't assume your street is fine just because a neighbour extended without planning permission. Rules can differ street by street. The only reliable check is the council's own planning register. What Kind of Extension Suits Your Home Victorian terraces dominate SW18, SW11, and SW17. Most of these homes suit a rear extension or a side return well. Some can handle a full wraparound. Loft conversions work well too, especially where the roof pitch already meets building rules. Bigger homes on wider plots have mor...

  Cobham sits within Elmbridge, one of Surrey's most Green Belt heavy boroughs, and that single fact shapes almost every extension project here. Do I need planning permission for a Cobham extension? It depends entirely on whether the property sits on Green Belt or protected land, which covers a large share of Cobham. Where Green Belt status applies, full planning permission is almost always required, even for a fairly modest extension, since national policy treats disproportionate additions to Green Belt properties as a specific planning test. Outside Green Belt boundaries, many Cobham homes retain standard permitted development rights, allowing extensions up to 3 metres for terraced and semi-detached properties, or 4 metres for detached homes, without a full application. Checking which category a specific property falls into is the first step cobham architects take before any design conversation begins.  What counts as a disproportionate addition on a Green Belt plot? Natio...
