What shapes a plot in Blackwood
When Caerphilly County Borough Council looks at a tandem plot, the first questions are usually about the drive: how close cars come to the front house’s windows, whether headlights will sweep across rooms at night, and whether the junction with the road is safe. Planning policy in the council’s Local Development Plan (LDP) sets the tests, and design guidance fills in the detail.
Daylight matters too. With the late-March sun climbing to just 38° at midday in Blackwood, an eaves line 5 metres up on the new home would throw shade roughly 6.3 m across the ground beside it. Keeping the new home low or well back protects the gardens on both sides.
The next steps, locally
We take a Blackwood plot with tricky access forward in three stages. First the legal access, confirmed with your solicitor. Then a layout that answers the questions Caerphilly County Borough Council asks about tandem and backland homes. Then the route you chose, whether that’s a sale, an option or a build. You can stop at any stage before signing.
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.
- Buying out a ransom strip or a neighbour’s land costs money and time, and the other owner can say no.
- Planning permission gives no right to cross land you don’t own; the legal access has to be secured separately.
Blackwood: questions to ask
How do I find out if a lane behind my Blackwood 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 get planning permission in Blackwood 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 Blackwood?
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.
Is a sprinkler system needed for a home at the end of a long drive in Blackwood?
It may be. In England, where a fire engine can’t get within 45 metres of all points inside the home, other measures, often sprinklers, may be accepted if building control and the fire service agree. In Wales, every new house needs sprinklers anyway. Building control decides what’s needed for the specific layout.
