The local picture in Llanidloes
Back lanes behind homes in SY18 can be public roads, private tracks or a mix of both. If the lane is maintained at public expense, it will be on the list of streets the highway authority keeps, which anyone can check. If it’s private, you need a right to use it with vehicles for a new home.
We check that before planning anything, then look at how Powys County Council is likely to judge a home reached from the back rather than past the front.
The next steps, locally
Call us or use the form and tell us roughly where the land is and how you reach it now. We check the title and the planning history around Llanidloes, then come back to you. If the access can’t be secured on sensible terms, we’ll say so plainly and early, and there is nothing to pay for the appraisal.
Free plot appraisal
We start with the access, not the plot: title plans, rights of way, the width on the ground and the route to the road. It’s a desktop check and a conversation, with a site visit if it looks viable, at no cost.
Title and access check
With your solicitor we confirm who owns every strip between the plot and the road, what rights already exist and whether they cover a new home. Any ransom strip or missing right shows up at this stage.
Secure the way in
If a right of way needs widening, a strip needs buying or a neighbour needs to come in, we agree the approach with you and negotiate it, so the terms are settled before planning money is spent.
Sale or build
Depending on the route you chose, the sale completes through a transfer of part, or you keep the land and we give a written quote for building the new home after design and survey.
Worth checking early
- A right of way that has served a garage or field for years may not legally cover a new house.
- Planning permission gives no right to cross land you don’t own; the legal access has to be secured separately.
- Buying out a ransom strip or a neighbour’s land costs money and time, and the other owner can say no.
Llanidloes: questions to ask
How do I find out if a lane behind my Llanidloes home is a public road?
The highway authority keeps a list of streets maintained at public expense, and anyone can inspect it free of charge. If the lane isn’t on it, it’s probably private, and you’ll need to know who owns it and whether your title gives a vehicle right of way that would cover a new home.
Can I build behind my house in Llanidloes if the only way in is my drive?
Possibly. That would be a tandem layout, with the new home behind yours sharing your drive. Powys County Council will look at the effect of cars passing your house, privacy, garden space and whether it suits the area. Fire and bin access also need checking. The decision is the council’s, and a good design improves the odds.
Can I get planning permission in Llanidloes before the access is sorted?
You can apply for planning on land you don’t own, as long as the owners are formally notified. But permission doesn’t give a right to cross anyone’s land. Most of the time it makes sense to agree access terms first, so the permission can actually be used.
Do you buy landlocked land in Llanidloes?
We can, where the access problem looks solvable. Any purchase is subject to survey, title and contract. If securing access would cost more than it’s worth, or the owner of the strip won’t deal, we tell you that early rather than wasting your time.
