Build a new home in your garden in Redhill

For a garden in Redhill to take a new house, three things have to line up: a safe way in, enough space to keep both homes private and light, and services that can reach the plot at sensible cost. Our free appraisal looks at all three before you spend anything.

If they line up, we move on to a measured survey, design and, where useful, pre-application advice from Reigate and Banstead Borough Council. Planning permission is the council’s decision, so the design is shaped around the tests its officers apply rather than the largest house the plot could possibly hold.

Before you decide in Redhill

Daylight is one of the first things Reigate and Banstead Borough Council will check on a garden house. At midday on 21 March the sun in Redhill stands roughly 39° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.2 m. On 21 December the sun is only about 15° 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.

Noon sun in Redhill on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.2 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

From first call to decision

If your Redhill 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.

  1. 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.

  2. 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.

  3. 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.

  4. 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

  • You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
  • Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
  • 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 Redhill

How close can a new house be to my own in Redhill?

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 Reigate and Banstead Borough Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.

Do you visit gardens in Redhill 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.

How long does planning take for a new home in a Redhill garden?

The statutory period for deciding a minor application, such as a single new home, is 8 weeks from the date the council receives a valid application, in both England and Wales. In practice many applications take longer, and the council may ask you to agree an extension in writing. Surveys and design before submission add time, and conditions may need approving afterwards.

Do new homes in Redhill 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.
