Extension and conversion builders in Greater Manchester: Homeowners vs renters
Homeowners:
You’re in charge of the project. That means hiring the builder, securing permissions, and paying for the work. You may need:
Planning permission (especially for double-storey builds or changes near boundaries)
Drawings from an architect or structural engineer
Building regs approval
If you’re not sure where to start, speak to a local builder or post your job to get help with the process.
Renters:
You’ll usually need your landlord’s approval to make any big changes. In most cases, your landlord will be the one arranging and paying for structural changes like loft conversions or extensions. That said, it’s worth flagging ideas if you think they’ll improve the property, especially if it means longer tenancies or fewer repairs.
