An existing access does not settle the case for its replacement.

The proposal and the decision

The application proposed rear and side extensions, a detached garage and a new access. The existing entrance was a narrow, gated arrangement beside the house. The scheme would replace it with a substantially wider access serving a new double garage and the rear garden.

Inspector N McGurk dismissed the appeal on 24 July 2026. Highway safety was the main issue. Although walls and hedging were to be removed, the proposed access would still have a substantial visibility shortfall. The highway authority’s evidence described a deficiency well beyond a marginal departure.

The inspector also considered Lindley Moor Road’s operation. It was a busy 40 mph classified road, with parked vehicles restricting views and affecting passing traffic. The footway on the opposite side ended nearby, creating a reason for pedestrians to cross. There was no collision cluster directly associated with the site, but evidence of collisions involving right turns onto the road was before the inspector.

Why the existing entrance did not resolve the issue

The appellant relied on the existing lawful access, which did not meet modern standards. At paragraph 13, the inspector explained that replacing one deficient access with another did not alter or mitigate the harm identified in the proposal.

For a project team, that is an important distinction. The existence of an entrance establishes part of the baseline. It does not establish that a wider access, a different position or a changed pattern of use will be acceptable. The proposed arrangement still needs to be assessed.

It would also be a mistake to read the decision as a visibility calculation alone. The inspector considered the road’s activity, parking, right turn movements and pedestrian crossing needs together. A drawing showing a clear frontage would not, on its own, describe all of those conditions.

What to take into the next layout

Establish the access position while the building and parking layout can still change. For the architect, that means reserving the space for visibility and pedestrian access before committing to extensions or a garage. For the client or landowner, it means identifying whether the intended access is a genuine constraint on the scheme.

The transport brief should record the existing arrangement, the proposed change and how the road operates. Where visibility is disputed, use an appropriate measured drawing and the speed evidence needed for that particular road. The notice does not report a speed survey; the inspector’s observations should not be presented as measured speed data.

Check the effect of parking and the route people take on foot. If an improvement depends on removing or preventing parking outside the site, establish how that could be delivered rather than drawing an unobstructed road and leaving the assumption unstated.

The practical lesson is to test the replacement on its own merits. Another proposal may achieve a different result, but it needs evidence of a safe arrangement that can actually be delivered.
