Extension Architecture

  A double storey extension is one of the most efficient ways to add real space to a home, but it's also one of the easiest to get badly wrong. The projects that run into trouble almost always trip over the same handful of mistakes, and every one of them is avoidable if you know what to watch for. Here are the five that cause the most grief, drawn from how double storey schemes actually play out. If you'd rather see the thinking in action, the Guildford architects video is a useful watch, but the mistakes below apply wherever your home is. Mistake one: assuming permitted development covers it The most expensive error happens before anything is even drawn. People assume their double storey extension falls under permitted development, and they're often wrong. Only a narrow category of two storey rear extensions qualifies as permitted development, and the conditions are strict. Most genuinely worthwhile double storey projects exceed t...

New Malden is one of southwest London's most distinctive suburbs, and not only for its architecture. The area holds the largest Korean community in Europe, giving its high street a character found nowhere else in the capital. Behind that vibrant frontage sits a residential landscape of Victorian and Edwardian houses , modern developments, and apartment complexes that homeowners are steadily transforming through thoughtful extensions. This is the story of what extending a New Malden home actually involves, told through the housing, the planning framework, and the decisions that shape a successful project. For a visual introduction from an experienced architect New Malden , the video is a useful starting point. The Houses That Define the Suburb New Malden developed primarily as a residential suburb from the late nineteenth century onwards, and its housing tells that story clearly. The classic properties feature red or yellow brick facades, decorative cornicing and ironwork, bay win...

Battersea's streets tell a consistent story. Victorian terraced houses built in the late nineteenth century dominate the area, and many have been divided into flats over the decades. For owners of these properties, the roof space sitting unused above represents one of the most valuable expansion opportunities in the whole of southwest London. A well designed loft conversion unlocks that potential, adding bedrooms, bathrooms, and genuine living space without extending the footprint. The video below covers the essentials, and this guide explains what actually works on Battersea's period housing. For a visual walkthrough from an experienced Architect Battersea , it is a useful place to start. Why Battersea Terraces Suit Loft Conversions The Victorian terraces across Battersea share characteristics that make them well suited to loft work. The pitched roofs, the ceiling heights, and the rear outrigger structures common to the period all create opportunities for adding usable space...

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...
