Caernarfon: light, access and policy
Sometimes the best scheme in Caernarfon takes in more than one garden. If your plot is short of access or depth, a feasibility study can test a combined layout with the gardens next door, as well as yours alone. We cover Caernarfon and nearby places such as Llangefni, Bangor and Bethesda, and in each case we show the owners how one shared access could serve several homes. Whether Gwynedd Council would support it depends on the design, the effect on the street and its policies.
How we’d take it forward in Caernarfon
Here’s how feasibility starts in Caernarfon. 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.
Feasibility report and options
A clear yes, no or maybe, the reasons behind it, and the routes open to you: apply for planning, build, sell or partner. You decide what happens next, with no obligation to use us for it.
Worth checking early
- Some ecology surveys can only be done at certain times of year, which can affect the programme.
- 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.
Your questions, answered for Caernarfon
How do I know if my garden in Caernarfon 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.
Can I get pre-application advice on a garden plot in Caernarfon?
Usually, yes. Most councils offer pre-application advice, and many charge a fee for it. Gwynedd 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.
Do I have to use you for planning after a feasibility study in Caernarfon?
No. The survey, report and concept designs are yours to use as you choose. You can take the scheme forward with us, through our planning permission or design and build services, or sell or partner on the plot with us, or use another firm. We would rather you made the decision that suits you.
How much does a feasibility study cost in Caernarfon?
It depends on the plot. A simple garden with a clear drive needs less work than one with protected trees, a flood zone or a complicated title. The first appraisal is free. After that we set out the scope and the price in writing, and you choose whether to go ahead before anything is commissioned.
