The local picture in Abercarn
Overshadowing is a common objection to garden homes, so we answer it with numbers. At noon on 21 March the sun over Abercarn 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. Caerphilly County Borough Council can then judge the scheme on evidence rather than impressions.
From first call to decision
To start, send us your Abercarn 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.
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
- 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.
Your questions, answered for Abercarn
Does a garden plot application in Abercarn 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.
What documents are needed for a garden plot application in Abercarn?
Caerphilly County Borough Council publishes a local validation list, as every council does. Typically you need the forms, a location plan with the site and access edged in red, a site plan, floor plans, elevations, an ownership certificate and the fee, plus reports the plot calls for, such as trees, ecology, drainage and access. We prepare to the list for your address.
Who decides planning applications for garden plots in Abercarn?
Caerphilly County Borough Council decides applications for addresses in Abercarn. 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.
What if my Abercarn 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.
