How it plays out in Merton
Daylight is one of the first things the London Borough of Merton will test on a garden scheme, so we test it first too. At midday on 21 March the sun over Merton sits about 39° above the horizon, and a typical two-storey eaves line around 5 m high throws a shadow of roughly 6.3 m. In late December the noon sun reaches only about 15°, so winter shadows run roughly three times longer. Plotting both on the measured survey shows where a new home can stand without darkening the gardens and rooms around it.
From first call to decision
Here’s how feasibility starts in Merton. You tell us about the plot, by phone or through the form, and we carry out a free desktop appraisal of access, title plan and planning context. If it looks viable we visit. If you want to go further, we send a written scope and quote for survey, constraints check and capacity study, and nothing starts until you agree.
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.
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.
Survey and constraints check
A measured survey of the plot and its surroundings, then a check of the title, services, trees, flood risk and heritage designations, so the design starts from facts rather than guesses.
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.
Worth checking early
- Title problems such as covenants, ransom strips or missing rights of way can take time and money to resolve.
- Pre-application advice is not binding, and the council’s decision on a formal application can still differ.
- A capacity figure is not a value; what a plot is worth depends on location, size, access and planning.
Your questions, answered for Merton
How many homes could fit in my garden in Merton?
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 Merton 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.
How much does a feasibility study cost in Merton?
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.
Can you check the title deeds on my Merton 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.
Do I have to use you for planning after a feasibility study in Merton?
No. The survey, report and concept designs are yours to use as you choose. You can take the scheme forward with us, through our planning permission or design and build services, or sell or partner on the plot with us, or use another firm. We would rather you made the decision that suits you.
