Before you decide in Clydach
Wherever your house sits across SA6 and SA7, 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 the City and County of Swansea 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.
What happens next in Clydach
If your Clydach plot already has planning permission, we begin by checking the approved drawings and conditions against the site. Some permissions need detailed design, discharge of conditions or a minor amendment before they can be built. We then prepare the technical drawings, arrange Building Regulations approval and the warranty, apply for utility connections and give you a written quote to build.
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.
Clydach: questions to ask
Can the new home in my Clydach garden connect to the main sewer?
Usually, yes, but the route and depth decide how easily. The new home needs its own foul connection, agreed with the water company, and gravity drainage is simplest where the sewer sits lower than the new floor. If it doesn’t, a pumped connection may be needed. Where a public sewer runs under your garden, a build-over agreement or diversion may also be required.
How close can a new house be to my own in Clydach?
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 the City and County of Swansea decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
Who decides planning for a garden house in Clydach?
The City and County of Swansea decides applications for addresses in Clydach, 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.
Will I pay Community Infrastructure Levy on a new home in Clydach?
Only if the City and County of Swansea has adopted a Community Infrastructure Levy charging schedule; not every council has. Where it applies, it can be charged on a new home of any size. A self-build exemption exists for people building a home to live in, but it must be claimed before work starts, so we check the position at design stage.
