Build a new home in your garden in Nailsea

Building a second home behind your own in Nailsea 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.

The local picture in Nailsea

Daylight is one of the first things North Somerset Council will check on a garden house. At midday on 21 March the sun in Nailsea stands roughly 39° 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 Nailsea: around 39° 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 Nailsea

Once you ask for an appraisal of your Nailsea garden, we start with the paperwork: the title plan, any covenants, flood maps, tree and conservation designations, and planning decisions on nearby plots. A short call follows, then a site visit if the plot passes the desk check. You get our straight view of what’s realistic and what happens next, with no obligation to go further.

  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 Nailsea

Do you visit gardens in Nailsea 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 close can a new house be to my own in Nailsea?

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

Can I build a house in my garden in Nailsea and keep the land?

Yes. On our design and build route you remain the owner while we design the home, apply to North Somerset Council for planning, deal with Building Regulations and build it. The finished house can be sold, let or kept for family. Whether your plot can take a house depends on access, space, neighbours and local policy, and the decision rests with the council.

How long does planning take for a new home in a Nailsea 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.
