Permitted development where access is over an unadopted road

Permitted development over an unadopted road is two separate questions that people routinely treat as one. The first is whether the works are development needing permission, answered by the General Permitted Development Order 2015. The second is whether you have the private right to take builders, deliveries and eventually occupiers along someone else's driveway, answered by the deeds. Planning rights say nothing at all about private rights, and a permitted development right is not a licence to trespass.

The awkward part is that nobody tells you. A prior approval notification comes back positive, the scaffolding arrives, and the first indication of a problem is a neighbour standing in the drive.

Why planning rights say nothing about private rights

A grant of planning permission removes a public law restriction on the use of land. It does not confer title, it does not create rights of way, and it is granted without prejudice to the rights of anyone else. Permitted development works the same way, just without a decision notice.

So a scheme can be entirely lawful in planning terms and entirely unlawful in practice, because every load of blocks crossing the drive is a trespass. The remedies sit in the civil courts, and an injunction restraining access mid-build is far more disruptive than an enforcement notice.

The reverse is also true. Having a right of way does not give you permission, and a generous easement is no answer to a planning objection.

Establishing ownership of the access strip

Start with the title. Order the register and title plan for your own property and, where the drive is separately titled, for the drive itself. Unregistered land is still common on older private roads, and an absence of a registered proprietor is a warning rather than a comfort.

Look for three things. Whether the strip is included in anyone's title or is a separate parcel. Whether your title includes an express right of way and in what terms. And whether there are rights reserved to others, or covenants restricting use.

Where the drive is unregistered and nobody can show title, the practical position is often that the frontagers own to the centre line, subject to the rights of others, but that presumption can be displaced and it is not something to assume on a development site.

If a third party owns the strip and you need a right you do not have, you are negotiating for a ransom. Valuation practice has long recognised that a strip controlling development value carries a share of that value, and the share is negotiated rather than fixed. Find out before you buy the land, not after.

Rights of way, deeds and prescriptive rights

An express right of way is defined by the words that grant it. Two questions follow: what the right is for, and what it permits.

A right granted for agricultural purposes does not automatically support a new dwelling. A right on foot does not carry vehicles. A right to a single cottage may not extend to five houses, because the law restrains a use so far beyond what was contemplated that it becomes excessive.

Where there is no express grant, a prescriptive right may have arisen through long use as of right, without force, secrecy or permission, over the statutory period. Prescriptive claims are evidence-heavy and are proved by statutory declarations from people who used the route, supported by dated material.

Two practical cautions. Use with the owner's permission does not build a prescriptive right, because permission defeats the claim. And a right acquired by use for one purpose is measured by that use, so twenty years of walking a dog does not produce a right to run a cement mixer.

Visibility splays on land you do not own

Where a scheme needs visibility splays, the land within them has to be controlled. A condition requiring you to provide and maintain a splay over land belonging to someone else is not something you can comply with, and a council should not impose one in that form.

The workable answers are a negatively worded condition preventing occupation until the splay is secured, or an agreement with the neighbouring owner recorded before the application is determined. Where the drive is private, the highway authority may not be involved at all, which removes the mechanism people usually rely on.

Vegetation is the recurring problem. A splay over a neighbour's hedge needs a right to cut it, maintained in perpetuity, not a friendly arrangement with the current owner.

Construction traffic over a shared drive

Even with a right of way, the extent of use during construction is a live issue. A right for all purposes with or without vehicles will generally support construction traffic, but it does not authorise damage, obstruction or storage on the drive.

Three things prevent most disputes:

1. A written record of the drive's condition before work starts, with photographs and, where the surface is poor, a survey.
2. An agreed repair obligation, with a figure or a mechanism, rather than an assurance that any damage will be put right.
3. Delivery management: vehicle sizes, times, and a rule against waiting on the drive.

Putting that into a Construction Traffic Management Plan gives it a planning home, and where the council conditions the plan it becomes enforceable rather than merely agreed. On schemes with no condition, a short side letter between the neighbours does the same job.

Where a highway authority is not involved

On an unadopted road there is no section 184 crossing application, no adoption agreement and often no authority interest at all. That sounds simpler. It is not, because there is no arbiter.

One statutory provision does bite. Where a new building fronts a private street, the advance payments code in the Highways Act 1980 can require a payment or security to the street works authority before the building is erected, so that the cost of any future street works is covered. Exemptions exist and the position varies by authority, so ask the street works team directly rather than assuming the code does not apply.

Maintenance liability is the other long-term issue. Private drives are usually maintained by the frontagers under the terms of their deeds, and adding a dwelling adds a contributor and a user. Check whether the deeds apportion the cost by frontage, by user or not at all.

Neighbour disputes during construction

Disputes on private drives escalate faster than almost anything else in residential development, because the parties see each other every day and the drive is the only route.

Practical prevention beats remedy. Tell the neighbours before the scaffold arrives rather than after. Give a named contact and a working phone number. Agree parking arrangements for trades in advance, because trade vans on a narrow private road generate more complaints than the building work does.

Where a genuine dispute about the extent of a right emerges, stop and take advice rather than pressing on. Continuing in the face of an asserted objection is what turns a negotiation into an injunction application.

Settling the position before work starts

Deal with all of it before you commit money.

Get the title checked by a conveyancer, with a written opinion on whether the right covers the intended use. Where the right is doubtful, negotiate a deed of easement and register it, or take a defective title indemnity policy if the risk is historic and remote. Record any agreement with neighbours in writing and, where it affects land, by deed rather than by email.

Then set the planning story out properly. A Planning Statement that describes the access, its ownership and the rights relied on saves an officer from guessing, and where the site boundary or garden has changed over time our note on measuring curtilage and the enlarged garden explains why the historic extent matters.

Illustrative example: a self-build plot at the end of a private lane serving four houses. The plot title carries a right of way for all purposes, granted in 1968 when the land was a paddock. The neighbours accept construction traffic once a condition survey and a repair contribution are agreed in writing. The visibility splay at the junction with the public road crosses a neighbour's verge, so a deed of easement is completed before the application is determined rather than left to a condition nobody could satisfy.

This is general guidance, not legal advice; check the position with your local planning authority, a conveyancer or a qualified professional before relying on it.
