How it plays out in Leigh
Daylight is one of the first things Wigan Council will check on a garden house. At midday on 21 March the sun in Leigh stands roughly 37° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.8 m. On 21 December the sun is only about 13° up and shadows stretch far longer.
That’s why the gap between your house and the new one, and the height of the new roof, are set by measurement rather than guesswork. A lower eaves line, a hipped roof or a single-storey section can make a real difference to the gardens either side.
From first call to decision
Getting started in Leigh 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
- 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.
- 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.
Questions about garden plots in Leigh
Will I pay Community Infrastructure Levy on a new home in Leigh?
Only if Wigan Council 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.
Can the new home in my Leigh 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 Leigh?
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 Wigan Council 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 Leigh?
Wigan Council decides applications for addresses in Leigh, using the council’s Local Plan, 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.
