Llantrisant: light, access and policy
Overshadowing is a common objection to garden homes, so we answer it with numbers. At noon on 21 March the sun over Llantrisant is about 38° above the horizon, and the shadow from a 5 m eaves line reaches about 6.3 m; on 21 December the sun rises to only about 15°.
Using those angles, we model shadows across neighbouring gardens and windows and adjust the height, position or roof shape of the new home until the effect is acceptable. Rhondda Cynon Taf County Borough Council can then judge the scheme on evidence rather than impressions.
What happens next in Llantrisant
To start, send us your Llantrisant address and a few photos of the garden, or give us a call. We check the title, access, constraints and nearby planning history, then talk it through with you. If the plot looks viable, we visit, explain whether an application is worth making and set out our fee and likely survey costs in writing.
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.
Decision and next steps
If permission is granted, we explain every condition and what must happen before work starts. If it’s refused, we review the reasons with you and set out the options: amend and resubmit, appeal, or stop.
Worth checking early
- Specialist surveys can be needed at short notice when a consultee raises an issue, adding cost and time.
- Permission doesn’t override private rights: covenants, ransom strips, sewer easements and party wall matters still need dealing with separately.
- Planning is the council’s decision; even a well-prepared application can be refused, and the costs of preparing it aren’t recovered.
Questions about garden plots in Llantrisant
What if my Llantrisant garden application is refused?
You can submit a revised application that addresses the reasons for refusal, appeal within 6 months of the decision date, or decide not to go further. Appeals go to the Planning Inspectorate in England or Planning and Environment Decisions Wales. We review the refusal and the officer’s report with you before recommending a route.
Who decides planning applications for garden plots in Llantrisant?
Rhondda Cynon Taf County Borough Council decides applications for addresses in Llantrisant. Small applications are usually decided by planning officers under delegated powers, and national and council rules set out when one can go to the planning committee instead. The decision is based on the council’s Local Development Plan (LDP), national policy and other material considerations, including neighbours’ and consultees’ comments.
How long will my Llantrisant 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.
How close to neighbours can a new home in Llantrisant be?
It depends on the council’s guidance and the window layout. Many councils use around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guide used by Rhondda Cynon Taf County Borough Council decides. Screening, levels, roof form and window positions can all change what is acceptable.
