Build a new home in your garden in Ashford, Surrey

If you own a house in Ashford with a long or wide garden, you don’t have to sell the land to benefit from it. We can design a separate new home for the plot, apply to Spelthorne Borough Council for planning permission, and build it while you carry on living next door.

When it’s finished, the house is yours to sell, let or keep for family. As a new name in the S&K Group we don’t trade on past jobs; every project starts the same way: a free, no-obligation appraisal of your garden, then a measured survey and design, then a written quote once the real costs are known.

Before you decide in Ashford, Surrey

Access is where a garden plot anywhere in TW15 tends to succeed or fail. A new drive needs enough width for cars, clear visibility where it meets the road, and enough distance from neighbouring windows to keep noise and headlights in check.

Policies in the council’s Local Plan, along with any highways advice the council receives, decide the detail for your address. We measure the gap beside your house on the first visit, and if it’s too tight for a home that can be approved and built safely, we’ll tell you before any design fees are spent.

Noon sun in Ashford on 21 March sits about 39° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.3 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.

How we’d take it forward in Ashford, Surrey

From appraisal to a decision from Spelthorne Borough Council, each step in Ashford is agreed before it starts. After the site visit we quote for survey and design; after design we prepare the application; after permission we deal with conditions and technical approvals and give you a written build quote. Each stage is a separate decision for you, with its cost set out first.

  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. 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.

  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

  • 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.
  • Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.

Questions about garden plots in Ashford, Surrey

Can the new home in my Ashford 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 you visit gardens in Ashford 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.

Who decides planning for a garden house in Ashford?

Spelthorne Borough Council decides applications for addresses in Ashford, 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.

Can I build a house in my Ashford 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.
