From the team at Approved Planning, supporting landowners with planning and development opportunities.
In some cases, yes – and it’s one of the most overlooked opportunities.
If you have unused space at the side of your property, there’s a strong chance it could support development depending on layout, access and planning context.
- Wide side plots
- Corner properties
- Unused access space
- Oversized residential plots

The short answer
Land at the side of a house can sometimes be developed, but it depends on how the site works in practice.
The key factor is whether a new dwelling can be created with proper access and layout.
This is worth checking if:
- You have a wide gap between your house and the boundary
- Your property sits on a corner
- There is existing access to the side
- Your plot feels larger than surrounding properties
If any of these apply, there may be development potential.
What determines if side land can be developed?
Access
Access is critical. If a new property can be safely accessed, the site becomes far more viable.
Width of the plot
The side space must be wide enough to accommodate a dwelling and allow separation from neighbouring properties.
Impact on neighbours
New development must sit comfortably within the surrounding area and not create unacceptable impact.
Planning context
Local planning policies influence what is acceptable, but do not automatically prevent development.
What can typically be built?
- A single dwelling beside an existing house
- A new property on a corner plot
- A small infill development
The key is designing something that fits the space properly.
The common mistake
Most homeowners assume side land is not usable.
In reality, this is one of the most common small development opportunities.
Common Questions About Side Plot Development
Can I build on land next to my house?
Sometimes, yes. It depends on width, access and how the proposal fits the surrounding area.
How wide does a side plot need to be?
There is no fixed rule, but it must be wide enough to accommodate a suitable dwelling and access.
Do I need planning permission?
Yes, in most cases you will need planning permission to build a new dwelling.
Will it affect my house value?
It can vary, but in many cases unlocking land value outweighs any impact.
Is side land valuable?
Yes. Side plots can carry significant value if they can support development.
