Mixed-Use Developments in North London

Combining residential, retail, workspace & community uses for stronger returns

Why mixed-use matters for developers

In London, land is scarce. Sites that once held only shops, offices, or light industrial units are increasingly being reimagined as mixed-use developments. For developers, these schemes unlock greater density, diversify income streams, and help win planning approval by delivering public value.

We’ve worked with clients in Camden looking to redevelop corner plots with retail below and flats above, with developers in Brent reimagining tired high streets with residential over co-working hubs, and with Barnet landowners keen to add community uses to strengthen their planning case.

Done well, mixed-use development is a win-win: residents enjoy amenities on their doorstep, councils see economic and social benefit, and developers realise higher GDVs.

The main types of mixed-use projects

Retail with residential above

A classic model in North London high streets. Ground floors retain active shopfronts, while upper floors are redeveloped into modern flats.

In Finchley, we helped transform a row of underused shops with dilapidated bedsits above into a new scheme of six modern apartments, keeping retail alive at street level.

Workspace and residential

With remote working reshaping demand, many older offices are being replaced or repurposed. Some developers now combine smaller-scale co-working or flexible studios at ground and first floor with flats above.

This model has been successful in parts of Camden and West Hampstead, where demand for local workspaces aligns with strong residential values.

Community uses plus residential

Adding uses such as medical centres, libraries, or gyms at ground level can help schemes win local support. In Barnet, a developer secured approval for a 20-unit block by including a GP practice at ground floor – something the council was keen to see delivered.

Redevelopment of corner or prominent sites

Prominent corner buildings, particularly on transport corridors, are prime opportunities for mixed-use. Councils often encourage active ground floors in these locations, making residential-only schemes less viable.

Planning permission for mixed-use schemes

Mixed-use developments always require full planning permission. Key considerations include:

Active frontages: councils want lively ground floors, not blank façades.
Servicing and access: deliveries, refuse storage, and separate entrances for residents.
Daylight/sunlight: ensuring flats above are not compromised by commercial uses below.
Noise control: acoustic separation between uses.
Policy alignment: boroughs often set quotas for retail retention or employment floorspace.

Borough nuances

Camden: strong emphasis on retaining retail in high streets; expects high design quality.
Barnet: supportive of suburban intensification, especially with community or healthcare uses.
Brent: balanced approach but rigorous daylight/sunlight assessments required.
Westminster: demanding, especially around heritage shopfronts, but supportive of active ground-floor uses.

How much do mixed-use schemes cost?

Costs depend on scale, complexity, and specification.

Standard mixed-use (retail + flats): £2,800–£3,800 per m²
High-spec schemes (workspace/community + resi): £3,800–£5,000+ per m²

Real-world examples

Barnet high street redevelopment: retail retained at ground, 10 flats above – £2.8m build cost, £6.2m GDV.
Camden corner site: co-working space with 8 apartments above – £3.1m build, £7.5m GDV.
Brent community-led scheme: GP practice plus 20 flats – £6.5m build, £12.8m GDV.

The key takeaway: combining uses can increase GDV while smoothing risk across different income streams.

Market and lifestyle benefits

For buyers and occupiers, mixed-use means:

Convenience: shops, gyms, or workspaces on the doorstep.
Community: schemes that feel connected to the neighbourhood.
Vibrancy: active ground floors that keep streets lively and safe.

For developers, it means:

Planning advantage: schemes more likely to win approval when they deliver community benefit.
Higher yields: commercial ground floors add rental income.
Stronger values: residential units above lively, well-designed ground floors attract premiums.

Case studies

Camden infill redevelopment: co-working at ground with 8 apartments above – won planning despite heritage constraints.
Barnet high street: retail units refurbished and integrated with 10 new flats – fully let within months.
Brent community scheme: GP practice at ground floor with 20 flats above – secured planning with strong local support.

FAQs

Do all mixed-use schemes need planning permission?
Yes – they always require full planning.

Can I convert existing offices to flats under PD?
Class MA allows some office-to-resi conversions, but it doesn’t apply if you’re retaining commercial space.

How do councils view loss of retail?
Boroughs usually insist on retaining some retail or community use in designated high streets.

Are mixed-use schemes more expensive to build?
They can be, because of acoustic separation and servicing needs – but returns are often higher.

Can residential units sit directly above noisy uses?
Yes, but only with robust acoustic separation. We design this in from the start.
