Before you start in Gwynedd
National policy in Wales sets the frame for garden applications in Gwynedd. The broad tests come from Planning Policy Wales (PPW), under which design quality, the character of the area and the living conditions of neighbours all carry real weight when a home is proposed in a garden. The local planning authority then applies its LDP and the council’s supplementary planning guidance and Technical Advice Note 12 on design. Our job is to show, with drawings and evidence, how a scheme meets those tests on your plot.
Planning authorities covering Gwynedd include Gwynedd Council, Isle of Anglesey County Council.
How it works
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.
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.

Questions about garden plot planning in Gwynedd
What drainage information do Gwynedd garden plots need?
For a new home, foul drainage must connect to a sewer or a suitable treatment system, and rainwater has to be handled on site. In practice that means approval from the SuDS Approval Body (SAB) before building starts. If a public sewer crosses the plot, the water company may also need a build-over agreement, separate from planning.
Who handles garden plot applications in Gwynedd?
Applications in Gwynedd go to the local planning authority for the address; authorities here include Gwynedd Council and Isle of Anglesey County Council. The authority applies its LDP alongside PPW and has its own validation list, design guidance and pre-application service. We confirm the right authority at the free appraisal and prepare to its requirements.
Is outline or full permission better for Gwynedd garden plots?
For most garden plots, full permission is the stronger option because privacy, daylight and access can only be judged properly with detailed drawings. Outline may suit an owner who intends to sell and wants a buyer to choose the house design. Where outline is used, we usually fix the access at that stage.
Do I need my own solicitor to sell a plot in Gwynedd?
Yes, always. Your solicitor checks the contract, deals with the transfer of part at HM Land Registry and asks your mortgage lender to release the plot if the house is mortgaged. On option and promotion agreements we cover your reasonable legal fees, with the cap agreed in heads of terms before work starts.
