Architects in Earlsfield
Earlsfield still feels like a village tucked inside Wandsworth, mostly because it's built from whole family houses rather than the converted flats found a short walk away in Tooting or Clapham. Design United Studio, led by director Jürgen Kuppers, designs extensions that keep that character rather than fighting it.
A Village Feel Built on Whole Houses
Why Earlsfield Rarely Has the Flat-Conversion Headaches Other Areas Do
Where Clapham and Tooting have a lot of Victorian houses split into separate flats, Earlsfield is still mostly made up of whole family houses. That means one owner, one decision-maker, and none of the freeholder consent complications that come with a leasehold flat.
It's still a proper planning process, just a more straightforward one to navigate, since a single household's needs drive the whole design rather than balancing several flats' worth of interests.

The River Wandle Shapes What's Possible Near King George's Park
Properties close to King George's Park or the River Wandle can need a watercourse or ecological consideration as part of a planning application, particularly for anything affecting drainage or the land right by the river corridor.
That's a different kind of check to the tidal flood risk assessment we'd look at for a property near the Thames, but no less worth getting right early.
Extending a Bay-Fronted Earlsfield Terrace
The bay-fronted Victorian terrace is the defining house type here, and it shapes how a loft conversion should sit above it. Kirana Laonipon, our Part II architectural assistant, designs dormers and roof extensions to respect the proportions of the bay below, so the addition reads as part of the house rather than an obvious afterthought.


Getting a Whole-House Project Right in One Go
Earlsfield buyers are often already settled families rather than first-time buyers stretching a budget, and that usually shows up in what they want from a project.
Combining a loft conversion, rear extension and interior reconfiguration into a single scheme, designed together from the start, tends to suit an Earlsfield household better than tackling each piece separately.
Working Within Earlsfield's Conservation Streets
Several streets in Earlsfield, particularly those closer to its historic centre, sit within a conservation area. That affects what can change on the front of a property without planning permission, and it's one of the first things we check on any Earlsfield project.

What Our Clients Say
"We wanted one project, not three separate headaches over three separate years. They planned the loft and the rear extension together from day one."
"Our garden backs onto the Wandle corridor, and I hadn't even thought about what that might mean until they raised it early on."
"The bay window upstairs matches the one below almost exactly. Small detail, but it's the reason the house still looks like ours from the street."
