Before you decide in Merton
A home placed behind another changes the light as well as the traffic. In Merton the sun peaks at roughly 39° in late March and barely 15° at the winter solstice, so shadows from even a modest building stretch a long way across a garden in the darker months.
That is why many tandem schemes use a single-storey or low-eaves design. It keeps upstairs windows from looking over neighbours and limits shadow. The London Borough of Merton decides, and its own guidance on separation distances sets the gaps it expects.
How we’d take it forward in Merton
Once you get in touch about land in Merton, we look at the title plan and any rights of way from the desk, then talk it through with you. If the access looks workable, we visit and measure the route, including the junction with the road. You get a plain account of the options before any planning work starts.
Free plot appraisal
We start with the access, not the plot: title plans, rights of way, the width on the ground and the route to the road. It’s a desktop check and a conversation, with a site visit if it looks viable, at no cost.
Title and access check
With your solicitor we confirm who owns every strip between the plot and the road, what rights already exist and whether they cover a new home. Any ransom strip or missing right shows up at this stage.
Planning application
We design a layout that answers the access, privacy and neighbour questions councils ask about tandem and backland plots, then apply. The council consults neighbours and decides, and the decision is always the council’s.
Sale or build
Depending on the route you chose, the sale completes through a transfer of part, or you keep the land and we give a written quote for building the new home after design and survey.
Worth checking early
- Tandem layouts affect the front house’s privacy and quiet, and councils weigh that carefully.
- Access is usually the deciding factor on these plots, so a large plot with a poor way in may not be a building plot at all.
- Planning permission gives no right to cross land you don’t own; the legal access has to be secured separately.
Your questions, answered for Merton
Can I build behind my house in Merton if the only way in is my drive?
Possibly. That would be a tandem layout, with the new home behind yours sharing your drive. The London Borough of Merton will look at the effect of cars passing your house, privacy, garden space and whether it suits the area. Fire and bin access also need checking. The decision is the council’s, and a good design improves the odds.
Do you buy landlocked land in Merton?
We can, where the access problem looks solvable. Any purchase is subject to survey, title and contract. If securing access would cost more than it’s worth, or the owner of the strip won’t deal, we tell you that early rather than wasting your time.
Could my neighbour and I in Merton share one new access?
Often, yes. If both your gardens are long, combining them can give one shared drive and a better layout than either garden alone. Each owner keeps their house, and a written agreement sets out how the value is shared fairly.
How long does sorting access on a Merton plot usually take?
It varies. Confirming an existing right of way can take a few weeks of solicitor time. Negotiating with a neighbour or a ransom strip owner often takes longer, and depends on how quickly everyone agrees and takes advice. Once we’ve seen the title and the route, we can give you a sensible estimate.
