Before you decide in Windsor
A measured survey in Windsor records the plot exactly: boundaries, levels, trees, drains, and the positions and heights of neighbouring windows. It is the base for everything else. From it we can plot the shadow a two-storey eaves line would cast, roughly 6.3 m at noon on 21 March when the sun is near 39° here, and the distances between the new home and the houses around it. The Royal Borough of Windsor and Maidenhead will expect the application drawings to be accurate to a survey like this.
The next steps, locally
The next step is a free appraisal of your Windsor garden. We look at the access, the shape of the plot, the title plan and the main planning constraints, then talk it through with you. Where the plot shows promise, we set out the surveys and design work it needs, with a written price for each stage, and you decide how far to take it.
Free plot appraisal
A desktop look at your plot, access, title plan and the planning picture, plus a conversation about what you want. If it looks viable we visit. There’s no cost and no obligation at this stage.
Access and capacity study
We test each workable route in and the number, size and position of homes the plot could hold, against separation distances, garden space, parking, bins and daylight for neighbours.
Concept designs and pre-application
Sketch layouts and simple elevations for the strongest options. Where it will help, we take one to the council for pre-application advice before anything is submitted.
Feasibility report and options
A clear yes, no or maybe, the reasons behind it, and the routes open to you: apply for planning, build, sell or partner. You decide what happens next, with no obligation to use us for it.
Worth checking early
- Title problems such as covenants, ransom strips or missing rights of way can take time and money to resolve.
- A capacity figure is not a value; what a plot is worth depends on location, size, access and planning.
- A feasibility study can end in a no; finding that out early costs far less than a refused application.
Your questions, answered for Windsor
How much does a feasibility study cost in Windsor?
It depends on the plot. A simple garden with a clear drive needs less work than one with protected trees, a flood zone or a complicated title. The first appraisal is free. After that we set out the scope and the price in writing, and you choose whether to go ahead before anything is commissioned.
How many homes could fit in my garden in Windsor?
That is what a capacity study answers. It tests options against separation distances from neighbours, garden space for each home, parking, bins and access, as well as the policies the Royal Borough of Windsor and Maidenhead applies. For many gardens the answer is one home; larger or combined plots can sometimes take more. We show the options on drawings so you can see why.
What if my Windsor garden plot fails the feasibility check?
Then you know before spending money on a planning application, and you know why. Sometimes a smaller scheme, an annexe, or working with the neighbours next door changes the answer, and we will say if so. If nothing does, you keep the survey and the report for the future. You are under no obligation to us either way.
Can I get pre-application advice on a garden plot in Windsor?
Usually, yes. Most councils offer pre-application advice, and many charge a fee for it. The Royal Borough of Windsor and Maidenhead’s website sets out its current arrangements, including how to apply, what to send and how long a response usually takes. We can prepare the information and attend any meeting for you. The advice isn’t binding, but it is a useful test before a full application.
