Before you decide in Brynmawr
Wherever your home sits within NP23, the street around it shapes what’s possible. Some roads already have houses built behind the originals, while elsewhere the gardens stay unbroken from end to end. Councils read that pattern when judging a new home, so we look at your surroundings as well as your plot.
The same applies if you live just outside Brynmawr, in nearby places such as Ebbw Vale, Tredegar and Abertillery. The first step doesn’t change: a free look at depth, access, levels and what a new home would mean for the people next door.
From first call to decision
Send us your address in Brynmawr and a rough idea of what you’d like. We check the planning history around you and the policies Blaenau Gwent County Borough Council applies, and look for anything in the title that could get in the way. If the garden passes those checks, we arrange a visit at a time that suits you and explain each route in plain terms.
Free plot appraisal
We look at your garden using maps, the title plan and the planning history around you, then talk it through with you. If it looks workable we arrange a site visit. There’s no cost and no obligation.
Measure and test the layout
We check depth, the width of the way in, levels, trees, drains and what lies behind, then sketch what could realistically fit: one home, two, or nothing worth pursuing, before anyone pays for an application.
Choose your route
You decide whether to sell the plot outright, sell subject to planning, grant an option, team up with neighbours, or keep the land and have us design, get planning for and build a home on it.
Planning application
We prepare the drawings and reports, usually take pre-application advice, and submit. The council consults neighbours and decides. Small schemes often take a few months from submission, longer if surveys or amendments are needed.
Worth checking early
- Cars passing beside your house to reach the new home bring noise and headlights; screening helps but doesn’t remove it.
- Neighbours are consulted and may object. The council decides, and a carefully designed scheme can still be refused.
- A shorter garden changes how your own house feels to live in and may affect what it is worth.
Your questions, answered for Brynmawr
Who decides planning for a home in a Brynmawr back garden?
Blaenau Gwent County Borough Council decides, using the council’s Local Development Plan (LDP), national policy and any local design guidance. It consults neighbours and other bodies before reaching a decision. We prepare the application and deal with the planning officer, but the outcome is always the council’s call.
Can I sell the end of my garden in Brynmawr and keep my house?
Yes. The plot is sold as a transfer of part and gets its own title at HM Land Registry. If your house is mortgaged, your lender must agree to release the plot. We can buy suitable plots with or without planning, always subject to survey, title and contract.
Can I build a house in my back garden in Brynmawr?
Possibly, if the garden is deep enough, has a safe way in and a new home wouldn’t harm the neighbours or the character of the street. A new separate home always needs planning permission, and Blaenau Gwent County Borough Council makes the decision. A free appraisal will tell you whether your garden is worth taking further.
Does it cost anything to have my Brynmawr garden looked at?
No. The garden plot appraisal is free and carries no obligation. It starts with a desktop check and a conversation, and we arrange a site visit if your garden looks viable. You only commit to anything once you’ve chosen a route and seen the terms in writing.
