Plan a residential development of new houses or apartments

Blueprint site layout of a new housing development with a loop road, rows of houses, an apartment block and trees inside a dashed boundary

For landowners, builders and small developers planning several new homes or a block of flats. Compare quotes from professionals who work out how many homes fit, design the scheme and steer it through planning.

A residential development might be a handful of houses on the edge of a village, a terrace on a former yard, or a block of apartments on a town centre site. Unlike a single new home, the design has to balance the number and mix of homes against council policy on density, space standards, parking, open space and affordable housing, while still producing a scheme that’s viable to build and sell. A good professional tests the site’s capacity early, coordinates the specialist reports the council will ask for, and designs homes people want to live in, with layouts, materials and landscape that sit well in their setting.

Questions people ask

How many homes can I fit on my site?

It depends on far more than the site area. Access, neighbours’ privacy, parking, open space, trees, flood risk, local density policy and the character of the surroundings all shape capacity. A capacity study tests several layouts against these constraints, and pre-application advice can show whether the council sees the numbers as reasonable before you commit to a full design.

Will I have to provide affordable housing?

Possibly. Requirements depend on the number of homes, the site area, the nation you’re in and your council’s local plan. In England, national policy generally doesn’t seek affordable housing on smaller schemes, though designated rural areas can be treated differently and your council’s local plan sets the detail. Where requirements apply and the scheme can’t support them, a viability assessment may be relevant. Your professional or a planning consultant can explain what applies to your site.

Can a residential development be built and sold in phases?

Often, yes. Larger schemes are commonly split into phases so homes can be built and sold while later parts are still being designed. A phasing plan agreed with the council can set when roads, open space and any affordable homes are delivered, and some conditions or payments can then be tied to each phase. Phasing affects the layout, site access during construction and cash flow, so it’s worth raising with your design team before the planning application is prepared.

What reports will the council ask for?

Each council publishes a local validation list, and residential schemes commonly need a transport statement, drainage strategy, ecology appraisal and tree survey, plus flood risk, noise, contamination, heritage or daylight assessments where relevant. Your professional can check the validation list and pre-application feedback so the right reports are commissioned at the right time, which helps the application be accepted without delay.

Do apartments need extra fire safety design?

Yes. Blocks of flats need careful design of stairs, escape routes, fire separation between flats, smoke control and access for firefighters, and a fire engineer is often involved. The approval route also depends on the building’s height and number of storeys, particularly in England, where higher-risk buildings follow a separate process. Raise the likely height and number of storeys at the outset, because the approval route and the stair and core layout follow from it.

Can the same professional help after planning permission?

Yes, if you appoint them for it. After permission, they can discharge conditions, prepare Building Regulations and construction drawings, put together a tender package and, if you wish, administer the building contract. If you switch to a design-and-build contractor after planning, they can help set out the employer’s requirements so the quality you gained permission for is protected.
