Redeveloping garage courts and yards behind houses

What counts as a garage court or yard behind houses?

A garage court is a group of garages or lock-ups, usually reached by a lane between or behind houses, often built at the same time as the homes around it. A yard can be a builder’s yard, a workshop, a former coal or storage yard, or a set of outbuildings tucked behind a row of houses.

What they share is that the land is already developed, sits behind existing homes and has a narrow way in. That makes them similar to backland garden plots in design terms, but quite different in planning and legal terms. Ownership can sit with a council, a housing association, a private landlord or the owner of a nearby house, and sometimes several of them at once.

Is a garage court previously developed land?

Usually, yes, if the garages were lawfully built and still stand or have left clear remains. The glossary to the National Planning Policy Framework for England defines previously developed land as land that has been lawfully developed and is or was occupied by a permanent structure and any fixed surface infrastructure associated with it, including the curtilage, and it includes large areas of lawfully developed hardstanding.

The same glossary excludes land in built-up areas such as residential gardens, parks, recreation grounds and allotments, and land where the remains of a structure have blended into the landscape. That is the key contrast with backland gardens: a garage court is usually brownfield land, while a back garden is not.

In Wales, Planning Policy Wales defines previously developed land as land occupied by a permanent structure and its associated fixed surface infrastructure, with the curtilage included. Its exclusions include parks and allotments, land where remains have blended into the landscape, land that is species-rich and biodiverse, and previously developed land later put to an amenity use. A garage court that has gone wild over many years may need an ecologist’s view.

Does national policy support building on garage courts?

In England, yes. The 2026 National Planning Policy Framework tells councils to look for ways of using previously developed land, including reusing service yards, lock-ups and car parks that are no longer needed. When deciding applications, it says substantial weight should be given to the benefits of making better use of vacant and underused land and of remediating contaminated land.

That support is not a blank cheque. The scheme still has to work on access, privacy, daylight, design and parking, and the council’s own Local Plan policies apply. Planning decisions are always the council’s.

In Wales, Planning Policy Wales puts weight on design quality, character and amenity, and the council’s Local Development Plan sets the local policies, including any on reusing previously developed land. Any scheme with a construction area of 100 square metres or more, which includes almost any garage court scheme, will also need approval from the SuDS Approval Body before construction starts.

What rights do the people who use the garages have?

The people who rent the garages, and the neighbours who use the lane, may have rights that have to be ended, moved or respected before building can start. Working this out early is often the biggest single task on a garage court.

Garage users usually rent on a licence or a lease. A licence can often be ended on the notice it sets out; a lease may give stronger rights, and some leases carry statutory protection. Your solicitor will check each agreement. Neighbouring houses may have rights of way over the lane to reach rear gates, parking areas or bin stores, written into their deeds.

Rights can also arise from long use. HM Land Registry’s guidance on prescription says a right of way can be claimed after at least 20 years of use without force, without secrecy and without permission. If residents have used the lane to reach their back gardens for decades, assume the right exists until a solicitor says otherwise.

• List every garage, who uses it, and on what written terms.
• Check every neighbouring title for rights over the court or lane.
• Note informal use: rear gates opening onto the lane, cars parked there, bins stored there.
• Plan how existing rights will be kept or rerouted in the new layout.

Who owns the land, and can you apply if you don't own all of it?

Ownership is often less tidy than it looks: the garages may belong to one owner, the lane to another, and a strip at the entrance to nobody obvious. A title search at HM Land Registry is the first step, and unregistered pieces need tracing through old deeds.

Anyone can apply for planning permission whether or not they own the land, but government guidance for England says every owner must be given notice and the correct ownership certificate completed. Owning the planning permission is not the same as being able to build: you still need ownership of, or rights over, every part of the site, including the entrance. A strip that controls the only access is a ransom strip, and its owner can ask for payment.

Will contamination be a problem?

It can be. Garage courts and yards have often been used for repairing cars, storing fuel, oil or chemicals, or burning waste, and older buildings may contain asbestos. HSE says asbestos can be found in any building built before 2000, which covers most garage courts.

Government planning guidance for England says responsibility for securing a safe development rests with the developer and landowner, and that applicants should provide proportionate but sufficient site investigation information. Councils commonly attach conditions requiring a remediation scheme and evidence that it has been carried out.

For a typical garage court, that often means a desktop study of past uses, then targeted soil sampling, then a remediation plan if needed. Costs depend on what is found, which is why investigation comes before a firm price.

What is involved in demolishing old garages?

Demolition needs planning around asbestos, wildlife, services and neighbours as well as the work itself. Under section 80 of the Building Act 1984, which applies in England and Wales, anyone planning a demolition must normally notify the local authority first and copy the notice to adjacent occupiers and the gas and electricity suppliers.

There are exceptions, including buildings with an external volume of not more than 1,750 cubic feet. A single small garage may fall below that, but a block of garages generally will not. Check also whether the demolition needs any consent of its own, especially in a conservation area.

Wildlife can affect timing. Natural England’s guidance says demolition, conversion and renovation proposals could affect a bat roost, and old garages with gaps under roof sheets or in brickwork can be used by bats or nesting birds. A preliminary ecological check before demolition is planned avoids delays.

How do access lanes affect what you can build?

The existing lane is usually the main constraint. Many were laid out for cars driving to garages, not for homes that need deliveries, bin collections and emergency services, and widening them is often impossible because houses sit on either side.

In England, Building Regulations guidance expects a fire engine to get within 45 metres of all points inside a house, with access routes of about 3.7 metres between kerbs and gateways of 3.1 metres. Where that isn’t possible, other measures, often sprinklers, may be accepted if building control and the fire service agree. In Wales, every new home must have sprinklers anyway.

Bins need planning too: residents shouldn’t carry waste more than 30 metres to the store, and the collection vehicle should be able to get within about 25 metres of it. On a long lane, that often means a bin collection point near the street.

The design also has to deal with the effect of cars passing the side and backs of existing houses, lighting along the lane, and how pedestrians and vehicles share it safely.

What about the parking that will be lost?

Councils and residents usually ask where the cars will go. If the garages are full and in use, losing them can push parking onto surrounding streets, and that can become a reason for objection or refusal.

A parking survey showing how many garages are actually used for cars, as opposed to storage, is often the most persuasive evidence. Many old garages are too small for modern cars. The new layout may also keep some parking for existing residents, or replace it nearby, and the council’s parking standards will guide how much the new homes need.

What kind of homes usually suit a garage court?

Garage courts often suit low, compact homes, such as single-storey or one-and-a-half storey houses, that sit comfortably behind existing back gardens without overlooking them. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall; your council’s own guide decides.

Roof shapes, window positions and rooflights are used to protect neighbours’ privacy, and a mews-style layout along the lane is a common answer. Keeping existing trees and adding planting helps with biodiversity, which England’s net gain rules and Wales’s net benefit policy both require the scheme to consider.

How do we approach garage courts and yards?

We start with a free appraisal: a desktop check of the title, planning history, access, flood risk and likely constraints, then a conversation, and a site visit if it looks viable. For garage courts the appraisal pays particular attention to users’ rights, ownership of the entrance and the lane width, because those decide whether a scheme is possible at all.

If it is, owners can sell the site, with or without planning, sell subject to planning, or grant an option or promotion agreement. Any direct purchase is subject to survey, title and contract. If you own the house next to a garage court rather than the court itself, combining your garden with the court can sometimes improve the access for both.
