Before you decide in Richmond upon Thames
A home placed behind another changes the light as well as the traffic. In Richmond upon Thames 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 Richmond upon Thames decides, and its own guidance on separation distances sets the gaps it expects.
The next steps, locally
The first step is a free, no-obligation appraisal. For a Richmond upon Thames plot with a difficult way in, that means checking who owns each part of the route, what rights exist and how wide it is on the ground. If a neighbour or a ransom strip is involved, we agree an approach with you before contacting anyone.
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
- Planning permission gives no right to cross land you don’t own; the legal access has to be secured separately.
- Buying out a ransom strip or a neighbour’s land costs money and time, and the other owner can say no.
- A right of way that has served a garage or field for years may not legally cover a new house.
Richmond upon Thames: questions to ask
Is a sprinkler system needed for a home at the end of a long drive in Richmond upon Thames?
It may be. In England, where a fire engine can’t get within 45 metres of all points inside the home, other measures, often sprinklers, may be accepted if building control and the fire service agree. In Wales, every new house needs sprinklers anyway. Building control decides what’s needed for the specific layout.
Can I build behind my house in Richmond upon Thames 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 Richmond upon Thames 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.
Could my neighbour and I in Richmond upon Thames 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 do I find out if a lane behind my Richmond upon Thames home is a public road?
The highway authority keeps a list of streets maintained at public expense, and anyone can inspect it free of charge. If the lane isn’t on it, it’s probably private, and you’ll need to know who owns it and whether your title gives a vehicle right of way that would cover a new home.
