Build a new home in your garden in Newtown

Our garden design and build service is for Newtown owners who want to keep their land and have a new home built on it, managed from the first appraisal to handover. We cover Newtown and the places around it, and manage every stage for you.

The order of work is clear. Appraisal and survey come first, then design and the planning application, then Building Regulations, the warranty, utility applications and a written quote. Only then does construction start, in stages with inspections, ending with a handover pack you can pass to a buyer, tenant or family member.

Before you decide in Newtown

Daylight is one of the first things Powys County Council will check on a garden house. At midday on 21 March the sun in Newtown stands roughly 37° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.5 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.

This section is worked out for the latitude of Newtown: around 37° of sun at midday in late March and about 14° at midwinter. It shows why the gap between your house and a new home behind it is about light as well as privacy. Garden assumed to face north.

How we’d take it forward in Newtown

Getting started in Newtown 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.

  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

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

Your questions, answered for Newtown

Can I build a house in my Newtown 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.

Do you visit gardens in Newtown 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.

Do new homes in Newtown 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.

Who decides planning for a garden house in Newtown?

Powys County Council decides applications for addresses in Newtown, using the council’s Local Development Plan (LDP), 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.
