Garden plot feasibility and design in Harrow

The cheapest time to find a problem with a garden plot in Harrow is before anyone draws a house on it. Covenants, sewers, protected trees, flood risk and narrow drives all turn up in a proper feasibility check, and most are far easier to deal with when they are known up front.

Our feasibility service covers the survey, title and constraints check, access options and a capacity study, followed by concept designs and pre-application advice from the London Borough of Harrow where it helps. It all begins with a free first appraisal, and every later stage has a written price that you approve before work starts, so you can stop at any point.

What the council will look at in Harrow

Access is where most garden plots stand or fall, in Harrow as anywhere. We measure every possible route in, whether a side drive, a gap left by a garage, a back lane or a shared way, and check its width, the sightlines onto the street, and the bin and emergency routes. Plots differ from one street to the next, so there is no standard answer for homes in HA1, HA2, HA3 and HA5. If the way in passes over someone else’s land, the title check shows whether a right of way exists, and the London Borough of Harrow’s highway advice shows what standard the route must meet.

What happens next in Harrow

The next step is a free appraisal of your Harrow 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.

  1. 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.

  2. Scope and written quote

    If you want to go further, we set out which surveys and checks your plot needs and what they will cost, in writing. Nothing is commissioned until you have agreed the scope and the price.

  3. 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.

  4. 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.

Worth checking early

  • Title problems such as covenants, ransom strips or missing rights of way can take time and money to resolve.
  • A feasibility study can end in a no; finding that out early costs far less than a refused application.
  • Some ecology surveys can only be done at certain times of year, which can affect the programme.

Harrow: questions to ask

How many homes could fit in my garden in Harrow?

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 London Borough of Harrow 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 Harrow 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 you check the title deeds on my Harrow property?

Yes. We obtain the title register and title plan from HM Land Registry and read them for restrictive covenants, rights of way, easements and any mortgage charge. If something needs a legal opinion, we flag it so your solicitor can advise. Title issues are far better found during feasibility than halfway through a planning application or a sale.

How do I know if my garden in Harrow is big enough for a house?

Size alone won’t tell you. What matters is whether there is a workable access, enough distance from neighbours’ windows, room for gardens, parking and bins for both homes, and nothing on the title or in policy that rules it out. A feasibility study checks each of those for your plot. The first stage, a free plot appraisal, gives you an early view.
