Garden plot feasibility and design in Cardiff

A feasibility study for a Cardiff garden plot ends with a straight answer: yes, no or maybe. Yes comes with a scheme that looks capable of planning permission. No comes with the reason. Maybe comes with what would need to change, such as a covenant released or a neighbour’s agreement.

From there you can apply for planning, build on the land, sell it or bring in a partner, or simply leave things as they are. We cover homes in and around Cardiff, and the first step, a free plot appraisal, costs nothing and commits you to nothing. You also keep every drawing and report you pay for.

What shapes a plot in Cardiff

Pre-application advice from Cardiff Council is often the last step of a feasibility study in Cardiff, and one of the most useful. Once the survey, constraints check and concept designs are done, we can put the strongest option to a planning officer and ask for a written view on the principle and the details. It isn’t binding, but it shows how the scheme measures up against the council’s Local Development Plan (LDP) and what an application would need. Any council fee is set by the council and shown in our written quote.

From first call to decision

Getting a straight answer about a garden plot in Cardiff costs nothing at the first stage. Send us a few photos and a rough idea of the plot, or call, and we’ll check it from the desk. If it’s not worth pursuing, we’ll say so and explain why. If it is, we’ll set out the next steps and their cost in writing.

  1. 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.

  2. 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.

  3. Survey and constraints check

    A measured survey of the plot and its surroundings, then a check of the title, services, trees, flood risk and heritage designations, so the design starts from facts rather than guesses.

  4. 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.

Worth checking early

  • Pre-application advice is not binding, and the council’s decision on a formal application can still differ.
  • A feasibility study can end in a no; finding that out early costs far less than a refused application.
  • Title problems such as covenants, ransom strips or missing rights of way can take time and money to resolve.

Cardiff: questions to ask

How many homes could fit in my garden in Cardiff?

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 Cardiff 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 Cardiff 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.

Can you check the title deeds on my Cardiff property?

Yes. We obtain the title register and title plan from HM Land Registry and read them for restrictive covenants, rights of way, easements and any mortgage charge. If something needs a legal opinion, we flag it so your solicitor can advise. Title issues are far better found during feasibility than halfway through a planning application or a sale.

Can I get pre-application advice on a garden plot in Cardiff?

Usually, yes. Most councils offer pre-application advice, and many charge a fee for it. Cardiff Council’s website sets out its current arrangements, including how to apply, what to send and how long a response usually takes. We can prepare the information and attend any meeting for you. The advice isn’t binding, but it is a useful test before a full application.
