Before you decide in Windsor
Overshadowing is one of the first things a planning officer checks on a garden scheme. In Windsor, the spring equinox sun reaches only about 39° at midday, which means a 5 m eaves line lays down a shadow around 6.3 m long. Come the shortest day, the sun climbs no higher than roughly 15° and the shade stretches far beyond that.
We model those shadows when we design the scheme, because a home that keeps light off your windows and the neighbours’ gardens is easier for the Royal Borough of Windsor and Maidenhead to approve. Sometimes that means a lower roof or a home set further back.
The next steps, locally
After you get in touch about a garden in Windsor, we run the free appraisal and explain which route we would recommend. If it is a sale subject to planning, we draft heads of terms covering the price, the scheme, the long-stop date and costs. Once your solicitor is happy and contracts are exchanged, we begin the planning work.
Free plot appraisal
We check your title, access, planning history and local policy from our desk, then talk it through with you. If a new home looks realistic, we visit the garden and tell you which route we think suits it best.
Heads of terms
We set out the price or price formula, what counts as satisfactory permission, the long-stop date, how any planning costs are treated and who pays which fees. You see all of it before instructing a solicitor.
Planning application
We commission the surveys, prepare the drawings, seek pre-application advice where useful and submit the application, normally at our cost. You see the plans before they go in, and the council makes the decision.
Completion, or you keep your land
Once a satisfactory permission is granted and any challenge period has passed, the sale completes within the agreed time and the plot gets its own title. If permission is refused and the contract ends, the land stays yours.
Worth checking early
- Once contracts are exchanged you are committed to sell if a satisfactory permission is granted.
- Capital Gains Tax timing on a conditional sale can differ from an ordinary sale; take advice from a tax adviser.
- The definition of satisfactory permission and the long-stop date decide how certain the sale really is; read both closely.
Your questions, answered for Windsor
How long might a sale subject to planning take in Windsor?
It usually runs for months, sometimes longer. Exchange often takes a few months; surveys and drawings take a few more; and the Planning Portal says most applications are decided within eight weeks of being valid, though garden schemes can take longer. The long-stop date sets the outer limit, agreed with you at the start.
Can I still use my garden in Windsor while the contract runs?
Yes. The plot stays yours until completion, so you carry on using it as garden. The contract will ask you not to build on it, fell trees or grant new rights over it without agreement, and to allow surveyors in from time to time, by arrangement. Your solicitor will point out anything specific.
What if I want to sell my Windsor house during a conditional sale?
Tell us as early as you can. The conditional contract is noted on your title, so your house buyer’s solicitor will see it. The two sales can usually be arranged together, but the order matters for the legal work and possibly for Capital Gains Tax, so take advice from a tax adviser too.
Who decides the planning application on a conditional sale in Windsor?
That is the Royal Borough of Windsor and Maidenhead’s decision as the local planning authority, made under the council’s Local Plan and the National Planning Policy Framework (NPPF). We prepare the application, submit it and answer the council’s questions, but the outcome isn’t ours to control. That’s why the contract has a long-stop date and says what happens if permission is refused.
