What the council will look at in Holyhead
Wherever your house sits across LL65, a new home behind it needs water, power and two kinds of drainage — one for waste, one for rain. We contact the utility providers early, because a long cable run, a sewer at the wrong depth or a public pipe under the lawn can change both the layout and the cost.
Rain from the new roof and drive has to be dealt with on site, and Isle of Anglesey County Council will want to see how. Where a public sewer crosses your garden, the water company may also need a build-over agreement before work starts, so we check sewer records at appraisal stage.
The next steps, locally
Getting started in Holyhead takes one step from you: send your address and a few photos of the garden, or call us. We check the title plan, access and planning constraints from our desk, then talk the plot through. If it looks viable we arrange a visit, discuss whether you want to sell, let or keep the new home, and set out the survey and design stage in writing before you commit.
Free plot appraisal
We check the title plan, access, constraints and planning policy from our desk, talk the plot through with you, and visit if it looks viable. There’s no cost and no obligation.
Survey and design
A measured survey records levels, boundaries, trees and neighbouring windows. We then design a layout and house that suit the plot, the street and your budget, and decide whether pre-application advice is worth seeking.
Planning and approvals
We submit the planning application and manage it to a decision, then deal with conditions, Building Regulations approval, the structural warranty, any build-over agreement and the new utility connections.
Handover
You receive the completion certificate, warranty documents, Energy Performance Certificate, manuals and utility details, so the new home is ready to move into, let or put on the market.
Worth checking early
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
- You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
- Planning can be refused, and money spent on surveys, design and the application isn’t recovered if it is — which is why we start with an appraisal.
Your questions, answered for Holyhead
How close can a new house be to my own in Holyhead?
There’s no single national distance. Many councils use separation guides of around 21 metres between facing back windows and around 12 to 15 metres between a back window and a blank side wall, but the guidance used by Isle of Anglesey County Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
Can I build a house in my garden in Holyhead and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Isle of Anglesey County Council for planning, deal with Building Regulations and build it. The finished house can be sold, let or kept for family. Whether your plot can take a house depends on access, space, neighbours and local policy, and the decision rests with the council.
Who decides planning for a garden house in Holyhead?
Isle of Anglesey County Council decides applications for addresses in Holyhead, using the council’s Local Development Plan (LDP), national policy and its own design guidance. Neighbours and consultees such as highways officers can comment, and the decision is made by the council’s planning officers or, where the rules allow, its planning committee. Pre-application advice from the council can help test a scheme before the formal application is submitted.
Do you visit gardens in Holyhead before giving advice?
We start with a desk review of the title plan, access, constraints and planning policy, then talk the plot through with you. If it looks viable, we arrange a site visit to see the access, levels, trees and neighbouring windows for ourselves. The appraisal is free and carries no obligation.
