Architects for Homeowners in North London

(Extensions, Conversions, New Builds & More)

When your home no longer fits your life

You can usually tell when a house is starting to work against you rather than with you. Maybe the kitchen feels like a corridor, the loft is a dumping ground, or you’re suddenly tripping over toys, bikes, and boxes that never seem to have a proper place. We hear it all the time from clients in Hampstead, Finchley, Barnet and beyond – “We don’t want to move, but we need the house to work harder for us.”

That’s exactly where we come in. At DOR Architects, we specialise in helping North London homeowners reimagine their homes – extending, reconfiguring, or even starting again from scratch with a new build.

What we do for homeowners

Every family, every house, and every site is different. But the patterns are surprisingly familiar.

  • Extensions – Ground floor side returns in Hampstead, double-storey additions in Finchley, or garden rooms in Barnet – extensions are often the first step in making space flow again.
  • Loft conversions – From simple dormers to full mansards, lofts are the most underused square footage in North London.
  • Garage conversions & outbuildings – Ideal for guest suites, gyms, or home offices.
  • Basement conversions – More complex, but transformative if you need serious extra space.
  • Internal reconfigurations – Knocking down walls, opening up dark kitchens, creating better circulation.
  • New build houses – For those bold enough to start again, whether replacing a tired bungalow in Totteridge or building on a garden plot.
  • Permitted development guidance – Many homeowners don’t realise just how much can be achieved without full planning permission.

Planning permission made easier

The rules for homeowners are a little kinder than for developers. Houses often enjoy permitted development rights, meaning lofts, extensions, and certain outbuildings can be built without a full application. Flats are more restricted, and conservation areas (like Hampstead Garden Suburb) bring another layer of control.

Because we work across North London’s boroughs – Barnet, Camden, Brent, Westminster and more – we know the nuances of each council’s approach. That local experience often makes the difference between a smooth approval and a frustrating refusal.

FAQs

Do I always need planning permission for an extension?
Not always. Many side, rear, and loft extensions fall under permitted development if your house qualifies. We’ll check this at the start.

Can you help with listed buildings?
Yes. We regularly work in conservation areas and with listed homes in Hampstead and Highgate, where sensitive design and heritage approvals are required.

How much does an extension cost in North London?
Costs vary depending on size and finishes, but we’ll always give you early cost estimates based on real build data, not guesswork.

Can you manage the whole build for me?
Yes – from first sketch to handing over the keys.
