How it plays out in Merthyr Tydfil
Access is where most garden plots stand or fall, in Merthyr Tydfil as anywhere. We measure every possible route in, whether a side drive, a gap left by a garage, a back lane or a shared way, and check its width, the sightlines onto the street, and the bin and emergency routes. Plots differ from one street to the next, so there is no standard answer for homes in CF47 and CF48. If the way in passes over someone else’s land, the title check shows whether a right of way exists, and Merthyr Tydfil County Borough Council’s highway advice shows what standard the route must meet.
The next steps, locally
Here’s how feasibility starts in Merthyr Tydfil. You tell us about the plot, by phone or through the form, and we carry out a free desktop appraisal of access, title plan and planning context. If it looks viable we visit. If you want to go further, we send a written scope and quote for survey, constraints check and capacity study, and nothing starts until you agree.
Free plot appraisal
A desktop look at your plot, access, title plan and the planning picture, plus a conversation about what you want. If it looks viable we visit. There’s no cost and no obligation at this stage.
Scope and written quote
If you want to go further, we set out which surveys and checks your plot needs and what they will cost, in writing. Nothing is commissioned until you have agreed the scope and the price.
Access and capacity study
We test each workable route in and the number, size and position of homes the plot could hold, against separation distances, garden space, parking, bins and daylight for neighbours.
Concept designs and pre-application
Sketch layouts and simple elevations for the strongest options. Where it will help, we take one to the council for pre-application advice before anything is submitted.
Worth checking early
- Title problems such as covenants, ransom strips or missing rights of way can take time and money to resolve.
- Pre-application advice is not binding, and the council’s decision on a formal application can still differ.
- Some ecology surveys can only be done at certain times of year, which can affect the programme.
Your questions, answered for Merthyr Tydfil
Is my Merthyr Tydfil garden in a flood zone or conservation area?
Both are public information. Flood zones are shown on the flood maps for planning in Wales, and Merthyr Tydfil County Borough Council publishes its conservation area boundaries and the listed buildings in its area. We check these as part of the free appraisal, along with Tree Preservation Orders, because each one changes what a scheme needs to show.
How many homes could fit in my garden in Merthyr Tydfil?
That is what a capacity study answers. It tests options against separation distances from neighbours, garden space for each home, parking, bins and access, as well as the policies Merthyr Tydfil County Borough Council applies. For many gardens the answer is one home; larger or combined plots can sometimes take more. We show the options on drawings so you can see why.
What if my Merthyr Tydfil garden plot fails the feasibility check?
Then you know before spending money on a planning application, and you know why. Sometimes a smaller scheme, an annexe, or working with the neighbours next door changes the answer, and we will say if so. If nothing does, you keep the survey and the report for the future. You are under no obligation to us either way.
How do I know if my garden in Merthyr Tydfil is big enough for a house?
Size alone won’t tell you. What matters is whether there is a workable access, enough distance from neighbours’ windows, room for gardens, parking and bins for both homes, and nothing on the title or in policy that rules it out. A feasibility study checks each of those for your plot. The first stage, a free plot appraisal, gives you an early view.
