Build a new home in your garden in Hayling Island

Building a second home behind your own in Hayling Island 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.

What shapes a plot in Hayling Island

Daylight is one of the first things Havant Borough Council will check on a garden house. At midday on 21 March the sun in Hayling Island stands roughly 39° above the horizon, so an eaves line about 5 m high casts a shadow of around 6.1 m. On 21 December the sun is only about 16° 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 Hayling Island: around 39° of sun at midday in late March and about 16° 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.

What happens next in Hayling Island

Once you ask for an appraisal of your Hayling Island 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. 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. 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.

  4. 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.

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.
  • Building and selling a new home can change your tax position compared with selling only your house; take advice from a tax adviser first.
  • You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.

Questions about garden plots in Hayling Island

Do you visit gardens in Hayling Island 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 Hayling Island?

Havant Borough Council decides applications for addresses in Hayling Island, 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 Hayling Island 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.

How long does planning take for a new home in a Hayling Island 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.
