Getting it right in Gwynedd
Side plots in Gwynedd often hide services. Drains, gas pipes and cables tend to run down the side of houses, and a public sewer under the plot may need a build-over agreement with the water company. New homes also need approval from the SuDS Approval Body (SAB) before building starts, and wildlife on the plot has to be considered under the Welsh requirement to deliver a net benefit for biodiversity. These checks rarely stop a good side plot, but they can shape where the new home sits and how close it comes to your house.
Planning authorities covering Gwynedd include Gwynedd Council, Isle of Anglesey County Council.
How it works
Free plot appraisal
We look at your plot on maps, the title plan and street views, check planning history nearby and talk it through with you. If a home beside yours looks possible we visit. No cost, no obligation.
Read the street
We measure the plot and record the building line, the gaps between houses, roof heights, materials and boundary walls, then check where a new drive could go and what drivers would be able to see from it.
Choose your route
Sell the plot outright, sell it subject to planning, or grant an option while you keep your house. Or keep the land and have us design, get planning for and build a new home on it.
Design and planning
We draw a home that sits in the street rather than fighting it, usually take pre-application advice, and submit the application. The council consults neighbours and decides; small schemes often take a few months.
Sale or build
For a sale, your solicitor handles the transfer of part and any release from your lender. For a build, a written quote follows design and survey, then we build, arrange the warranty and hand over.
Corner and side plots in towns across Gwynedd
Questions about corner and side plots in Gwynedd
Are corner plots easier to develop than back gardens in Gwynedd?
Often, because a new home on a corner or side plot usually has its own frontage and drive. But the council will look closely at the street scene, the building line and visibility at the junction. Some corners were designed to stay open, and that can count against a new home.
Which councils decide side plot applications in Gwynedd?
The council for your address decides. Across Gwynedd, the planning authorities include Gwynedd Council and Isle of Anglesey County Council, and each has its own plan and guidance on how new homes should fit into existing streets. We look up the policies that apply at your exact address before suggesting a design.
What design rules apply to side plot homes in Gwynedd?
National policy, PPW, sets the broad tests, and each council adds its own plan and design guidance. Expect questions on building lines, spacing, roof height, materials, parking, bins and light to neighbouring windows. The detail varies by council, so we always check locally.
Which national rules apply to a new home in Gwynedd?
Garden schemes here sit under Planning Policy Wales (PPW), with the local detail coming from the council’s Local Development Plan (LDP). New homes must also meet the Building Regulations as they apply in Wales. That affects things such as sprinklers, which every new home in Wales must have. On drainage you’ll usually need approval from the SuDS Approval Body (SAB) before building starts, and land purchases fall under Land Transaction Tax (LTT). We check which rules apply to your plot as part of the free appraisal.
