Before you decide in St Asaph
Every application Denbighshire County Council receives for a St Asaph address is tested against the council’s Local Development Plan (LDP). Policies on housing, design, residential amenity, parking and trees will all be relevant to a garden plot, and some councils have specific policies or guidance on garden and backland development.
We read the policies that apply to your address before designing anything, and write the planning statement around them. Where the plan is silent or out of date, national policy carries more weight, and the statement explains how the scheme meets it.
The next steps, locally
When a decision on your St Asaph application arrives, we go through it with you line by line. If permission is granted, we explain each condition, which ones must be approved before work starts, and the time limit. If it’s refused, we review the reasons and set out the options, with a straight view on the prospects of each.
Free plot appraisal
We review the title plan, access, constraints, policy and planning history around your address, then talk it through with you. If the plot looks viable we visit, and tell you plainly whether an application is worth making.
Surveys and design
A measured survey comes first, followed by the specialist surveys the plot needs, such as trees or ecology. The layout is designed around access, privacy, daylight, parking, bins and garden space for both homes.
Pre-application advice
Where policy is tight or the plot unusual, we put a draft scheme to the council’s planners first. Their written response shows which issues to fix before you pay the full application fee.
Submit and manage
We complete the forms, ownership certificate, drawings and statements, pay the fee on your behalf and submit. During consultation we answer officers’ questions, respond to consultees and agree amendments where they help.
Worth checking early
- Planning is the council’s decision; even a well-prepared application can be refused, and the costs of preparing it aren’t recovered.
- Neighbours have a formal say during consultation, and the council must weigh any planning objections they raise.
- Conditions can add cost and work before building starts, such as approved drainage details, tree protection or a construction management plan.
Your questions, answered for St Asaph
Can I sell my St Asaph garden plot once it has planning permission?
Yes. Planning permission stays with the land, so the plot can be sold with it and the buyer can build the approved scheme, subject to any conditions. The plot will need its own title through a transfer of part at HM Land Registry, and any mortgage lender will need to release it. Take advice from a tax adviser before selling.
Is pre-application advice available in St Asaph?
Most planning authorities, including Denbighshire County Council, offer pre-application advice, usually for a fee, with their own response times. It isn’t compulsory and doesn’t bind the final decision, but for a garden plot with a tight access, strict policy or an earlier refusal, it can show which issues to resolve before you apply formally.
How long will my St Asaph garden plot application take?
The statutory period for a minor application, such as one or a few new homes, is 8 weeks from validation, in both England and Wales. Many take longer, and the council may ask you to agree an extension in writing. If no decision is made in time and no extension is agreed, you can appeal for non-determination.
Does a garden plot application in St Asaph need a tree survey?
Often, yes. If trees on or near the plot could be affected, councils usually expect a tree survey showing root protection areas and how they’ll be protected during building. Trees with a Tree Preservation Order, or in a conservation area, need consent or notice before any work, and can shape where the house and drive go.
