What the council will look at in Machynlleth
A home placed behind another changes the light as well as the traffic. In Machynlleth the sun peaks at roughly 37° in late March and barely 14° at the winter solstice, so shadows from even a modest building stretch a long way across a garden in the darker months.
That is why many tandem schemes use a single-storey or low-eaves design. It keeps upstairs windows from looking over neighbours and limits shadow. Powys County Council decides, and its own guidance on separation distances sets the gaps it expects.
From first call to decision
We take a Machynlleth plot with tricky access forward in three stages. First the legal access, confirmed with your solicitor. Then a layout that answers the questions Powys County 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.
Planning application
We design a layout that answers the access, privacy and neighbour questions councils ask about tandem and backland plots, then apply. The council consults neighbours and decides, and the decision is always the council’s.
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.
- Tandem layouts affect the front house’s privacy and quiet, and councils weigh that carefully.
- Access is usually the deciding factor on these plots, so a large plot with a poor way in may not be a building plot at all.
Your questions, answered for Machynlleth
What if a neighbour in Machynlleth owns the strip I need to cross?
Then you need their agreement, either to buy the strip or to grant a right of way over it. Terms are negotiated, often as a one-off payment or a share of the value the access creates. Both sides should take legal advice. We can make the approach with you.
Could my neighbour and I in Machynlleth share one new access?
Often, yes. If both your gardens are long, combining them can give one shared drive and a better layout than either garden alone. Each owner keeps their house, and a written agreement sets out how the value is shared fairly.
How do I find out if a lane behind my Machynlleth 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 Machynlleth 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.
