Terraced homes
Narrower gardens often suit a compact footprint; materials may need to come through the house or a rear lane.
Semi-detached homes
Side access usually makes delivery easier and gives more flexibility on size and position.
Detached homes
Larger plots allow bigger rooms and combined uses, while still respecting permitted development limits.
Listed or conservation-area homes
Extra planning controls are likely, so we check the rules before any design work.

Choosing the right garden annexe
Your garden and ground
Slope, ground conditions, trees and drainage affect the base and where the room can go.
Property type
Terraced, semi-detached and detached homes differ in access, garden size and neighbour impact.
Finish and performance
Cladding, glazing and insulation choices shape how the room looks and how comfortable it is.
Preparation
Clearing the site, groundworks and bringing in power, data or water need planning in advance.
Budget
Size and specification drive cost more than anything — we help you prioritise.
Maintenance
Different cladding and roof finishes need different levels of upkeep over time.
Rules that apply
Planning permission and building regulations are separate; which apply depends on size, position and use.
