Build a new home in your garden in Chalfont St Peter

Building a second home behind your own in Chalfont St Peter is a construction project with one unusual feature: you live beside the site from the first spade to the last coat of paint. That shapes how we plan it, from the fence that separates your garden on day one to where deliveries park.

The route covers everything between an idea and a finished house. We survey and design, prepare and submit the planning application, arrange Building Regulations approval and the structural warranty, organise new water, drainage and electricity connections, and then build. You keep ownership of the land throughout.

Chalfont St Peter: light, access and policy

Daylight is one of the first things Buckinghamshire Council will check on a garden house. At midday on 21 March the sun in Chalfont St Peter stands roughly 38° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.3 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.

This section is worked out for the latitude of Chalfont St Peter: around 38° of sun at midday in late March and about 15° 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 Chalfont St Peter

Getting started in Chalfont St Peter 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. 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

  • 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.

Chalfont St Peter: questions to ask

Can the new home in my Chalfont St Peter 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 Chalfont St Peter 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 Chalfont St Peter 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.

Will I pay Community Infrastructure Levy on a new home in Chalfont St Peter?

Only if Buckinghamshire Council 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.
