How it plays out in Crawley
In Crawley, applications for a new home in a garden are decided by Crawley Borough Council, which weighs them against the council’s Local Plan and national policy. Officers look at access, privacy, daylight, parking, bins, drainage and how much garden is left for each house, and neighbours can comment during consultation.
We read the local policies and any design guidance before drawing a line, and check the planning history of nearby plots for decisions that show how the council has applied them. If the policy picture is uncertain, pre-application advice lets us test the scheme with officers before the formal application goes in.
From first call to decision
Once you ask for an appraisal of your Crawley 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.
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.
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.
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.
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
- Your own garden gets smaller and the new home will be visible from your house, so screening and separation matter for both homes.
- You fund the build and carry the cost risk; ground conditions, sewer diversions or supply upgrades found later can move the price.
- 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.
Crawley: questions to ask
Can I build a house in my garden in Crawley and keep the land?
Yes. On our design and build route you remain the owner while we design the home, apply to Crawley Borough 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 close can a new house be to my own in Crawley?
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 Crawley Borough Council decides. Window positions, ground levels, roof shape and screening all affect what is acceptable, which is why we survey before we design.
Do you visit gardens in Crawley 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.
Can I build a house in my Crawley 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.
