New Build Residential Developments in North London

Maximising sites, unlocking planning, and delivering high-value homes

Why developers choose new build schemes

For developers, the equation is clear: land value + planning permission + design quality = profit. Whether it’s replacing a tired bungalow in Barnet, assembling a backland plot in Finchley, or seeking to redevelop a brownfield site in Camden, new build residential is where serious returns are made.

But it’s also where the risks are greatest. Get the design wrong, and planners push back. Overestimate the market, and sales stall. Ignore construction realities, and budgets spiral.

At DOR Architects, we bring together design flair, planning expertise, and practical cost awareness to help developers in North London turn underused sites into high-performing assets.

Types of new build residential projects

Demolition and rebuild

The most straightforward development path: acquire a dated house or small commercial building, demolish, and replace with multiple units. In Barnet, we’ve helped clients replace a single dwelling with five high-spec flats – multiplying value several times over.

Infill developments

London has endless small sites: side plots, end-of-terrace gaps, old garages. With clever design, these can become profitable micro-developments. Camden, for example, has seen many successful schemes on narrow infill plots, each maximising overlooked land.

Backland sites

Deep plots in Finchley and Totteridge sometimes allow for new dwellings behind existing houses. These schemes are sensitive, requiring careful handling of access and overlooking, but when done right, they unlock hidden land value.

Brownfield redevelopments

Old garages, workshops, or redundant retail units often carry huge potential for residential redevelopment. In Cricklewood, a light industrial site was transformed into a 12-unit scheme once planning consent was secured.

Planning permission for developers

The challenge

Securing permission is often the make-or-break stage for developers. Boroughs scrutinise density, design quality, and affordable housing contributions.

Key planning factors

Design quality: Councils demand architecture that enhances local character.
Unit mix: Policies often require a balance of 1-, 2- and 3-bed homes.
Affordable housing: Thresholds vary by borough and scheme size.
Daylight/sunlight studies: Crucial in tight urban sites.
Parking and transport: Highly scrutinised in areas with limited on-street capacity.

Borough differences

Barnet: more accommodating of suburban intensification, especially along transport corridors.
Camden: strict on design quality, heritage, and affordable housing.
Brent: open to redevelopment but rigorous on daylight/amenity testing.
Westminster: among the strictest, especially in conservation-heavy areas.

How much does a new build development cost?

Typical build costs in North London:

Standard flats: £2,500–£3,500 per m²
High-spec apartments: £3,800–£5,000+ per m²
Townhouses: £3,000–£4,000 per m²

Real-world examples

Barnet suburban site: 5 flats replacing a single house – £1.1m build cost, £2.4m GDV.
Camden infill scheme: 3 mews houses on a narrow plot – £1.2m build, £2.8m GDV.
Brent brownfield site: 12-unit redevelopment of old workshops – £4.6m build, £8.5m GDV.

These numbers underline why design and planning strategy are critical – they directly influence land value uplift and exit figures.

Lifestyle and market benefits

Well-designed residential schemes don’t just perform better on paper – they sell faster and at stronger prices. Buyers in Hampstead, Finchley and Barnet pay a premium for:

Light-filled interiors with good ceiling heights.
Practical layouts that maximise usable space.
Outdoor amenity (balconies, gardens, terraces).
Strong sustainability credentials (EPC A, low energy bills).

Case studies

Barnet replacement dwelling: one house demolished, five flats approved – ROI doubled within two years.
Camden infill site: disused garages transformed into three mews houses, approved despite heritage sensitivities.
Cricklewood brownfield: redundant workshop converted into 12-unit residential scheme, maximising site potential.

FAQs

Do all new builds need planning permission?
Yes – unlike extensions, every new dwelling requires full planning approval.

How do I know if my site has potential?
We offer feasibility studies that assess density, planning policy, and viability.

What about affordable housing contributions?
Thresholds vary – smaller schemes may avoid them, but borough policies differ.

How long does planning take?
6–12 months is typical, though larger schemes can take longer.

Can you help with finance appraisals?
Yes – we provide design input into financial models, helping you secure funding.
