Build up:

• Loft conversion – Turn your attic into a bedroom, office or bathroom. A smart way to use space you already have.
• Second storey – Add a whole new floor on top. It’s a bigger project, but wow, does it give you room to grow.
• Dormer – A smaller change that adds headroom and light to your loft.

Build out:

• Single-storey extension – Popular for creating open-plan kitchens or family spaces. Often doesn’t need planning permission if it meets certain rules.
• Double-storey extension – Twice the floors, twice the space. A bigger investment, but worth it for families that need room.
• Side return – Great for terraced homes; it makes use of that little alleyway down the side.
• Conservatory – Light, bright, and usually cheaper than brick, though less practical all year round.

Build down:

• Basement conversion – Turn an existing cellar into a gym, playroom or guest bedroom.
• Basement extension – Dig down to create a whole new level. It’s discreet but can be more complex and costly.
