Redruth: light, access and policy
Daylight is one of the first things Cornwall Council will check on a garden house. At midday on 21 March the sun in Redruth stands roughly 40° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.0 m. On 21 December the sun is only about 16° 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 Redruth 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
- 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.
- You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
- A build next door means months of noise, deliveries and contractors near your home; good planning reduces the disruption but doesn’t remove it.
Redruth: questions to ask
How close can a new house be to my own in Redruth?
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 Cornwall Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
Can the new home in my Redruth 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.
Do new homes in Redruth need a structural warranty?
If the house will ever be sold or mortgaged, in practice yes. Mortgage lenders usually expect a 10-year structural warranty on a new home, though some accept an architect’s or surveyor’s certificate, and a warranty provider inspects the work at stages during the build, so it has to be in place before construction starts. Building control approval is separate and also required; a buyer’s solicitor will ask for both.
Can I build a house in my Redruth garden and then sell it?
Yes. You keep the land while the home is built, then sell the finished house. Before building starts, the plot should be given its own title through a transfer of part at HM Land Registry, and if your house is mortgaged your lender must agree to release the plot. Selling a home you’ve built can change your tax position, so take advice from a tax adviser first.
