What the council will look at in King's Lynn
Daylight is one of the first things Borough Council of King’s Lynn and West Norfolk will check on a garden house. At midday on 21 March the sun in King’s Lynn stands roughly 37° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.6 m. On 21 December the sun is only about 14° 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.
How we’d take it forward in King's Lynn
Getting started in King’s Lynn 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.
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.
Written quote and build
Once design and survey are complete you get a written quote. The build runs in stages — access and groundworks, foundations, frame and roof, fit-out and external works — with inspections at each key point.
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
- Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.
- 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 King's Lynn
Will I pay Community Infrastructure Levy on a new home in King's Lynn?
Only if Borough Council of King’s Lynn and West Norfolk 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.
Do you visit gardens in King's Lynn 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.
Can I build a house in my garden in King's Lynn and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Borough Council of King’s Lynn and West Norfolk 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 King's Lynn?
Borough Council of King’s Lynn and West Norfolk decides applications for addresses in King’s Lynn, 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.
