What we do

What does DOR Architects do?

DOR Architects is a RIBA Chartered, ARB registered practice in north London. We help developers, community bodies and homeowners understand what a site can achieve, design schemes councils are likely to approve, and produce drawings builders can price, drawing on real construction, finance and development experience to reduce risk.

Why it matters

Most schemes fail long before construction. Ours are designed to get approved and get built.

Planning refusals, tender prices that blow the budget, drawings contractors can’t build — these are the risks that stall London sites. Having run a construction firm for over a decade, we design with the site in mind from the first sketch: schemes councils approve, contractors can price, and people love to live and work in.

Our approach

The risks we take off your plate.

For developers

Site appraisals, planning and buildable schemes for developers in North London

We help developers understand what a site can achieve before they commit: feasibility and massing studies, planning strategy and pre-application advice, change of use (including commercial to residential conversions) and small residential schemes. See our site feasibility and planning services for developers, or try our checker for how many flats a building could take. Having run a construction firm for over a decade, we produce drawings contractors can price accurately.

Westminster

In St John's Wood and nearby streets, extensions and roof changes are often in conservation areas or near listed buildings. We prepare carefully detailed drawings that respect the street's character.

06

Harrow

Larger plots around Stanmore suit generous single and two-storey extensions. We shape schemes to Harrow's residential design guidance from the first sketch.

Questions

Common questions

Do I need planning permission for a rear extension or loft?

Not always. Many single-storey rear extensions and loft conversions fall under permitted development. We check your address, planning history and any conservation area first, then tell you whether full planning is needed. If not, a Certificate of Lawfulness is an optional extra for peace of mind.

Should I use an architect or an architectural technician?

For a simple box extension, either can draw it. An architect also shapes the layout, light and flow so the extra space really works, and you deal with the principal, RIBA Chartered and ARB registered, on every project, not a junior.

How do you keep the design buildable and on budget?

We ran a construction firm for over a decade, so our drawings are detailed for builders to price accurately. You see the design in 3D before you build, so decisions are made early, not on site.

Can you tell me what my site could achieve before I buy?

Yes. A feasibility and massing study tests what a site could realistically achieve against local planning policy, so you understand its potential and risks before you commit.

Do you handle change of use?

Yes. We advise on planning strategy and prepare applications for change of use and small residential schemes, including pre-application discussions with the council where useful.
