Army Town Extensions — SFA Restrictions and Private Property Rules in GU11
Aldershot's military garrison character means a significant proportion of GU11 properties are Service Family Accommodation — where extensions and alterations are controlled by the housing management contractor rather than the private planning system.
The area is a town in Hampshire, South East England, administered by Rushmoor Borough Council. The postcode districts covering the area are GU11, GU12.

What to Expect from a Aldershot Building Extension
Rushmoor Borough Council handles planning for the GU11 and GU12 postcodes. Single-storey rear extensions within the standard permitted development limits proceed without a planning application. The military housing legacy in some parts of Aldershot creates a more uniform housing stock than in other comparable towns — brick semi-detached properties of a consistent era — and the planning framework for these properties is generally uncomplicated.

Frequently Asked Questions
Do I need planning permission for a house extension in Aldershot?
For most privately owned or rented Aldershot properties, single-storey rear extensions up to 3 metres (semi or terrace) or 4 metres (detached) may fall under permitted development without needing full planning permission. Larger extensions under the Neighbour Consultation Scheme can reach 6 or 8 metres but require notification. Conservation area properties need full planning permission for side extensions and some rear extensions. Rushmoor Borough Council handles planning for the GU11 postcodes.
Can I extend a Service Family Accommodation property in Aldershot?
No — SFA properties cannot be extended by the resident. The housing management contractor controls all structural alterations to SFA housing. If you are in SFA and require more space, the route is through your housing management office rather than the private planning system. All extension information on this page applies to privately owned or privately rented residential properties in the GU11 area.
Does a building extension in Aldershot need Building Regulations approval?
Yes — Building Regulations approval is required for virtually all extensions regardless of whether planning permission is needed. Building Regulations cover structural safety, fire separation, insulation, drainage, and ventilation. Rushmoor Borough Council's building control handles approvals for GU11. Failing to get Building Regulations sign-off creates problems when you sell — buyers' solicitors will ask for it.
How long does a house extension take to build in Aldershot?
A standard single-storey rear extension typically takes 10 to 16 weeks from groundworks to completion. This excludes the pre-construction period for design, planning (if needed), Building Regulations, and contractor procurement — which commonly adds 3 to 6 months before work starts. For SFA-adjacent properties, check whether your proposed extension affects any MOD land boundaries before starting.
