Great Customer Service -

The quickest way to know whether or not your loft can be converted is to look down your street. If you find loft conversions in other houses, it’s very likely that you can have one.

You might also have to figure out what the internal loft height is. If it's at least 2.2m or 2.5m tall, then you should have no problem converting it.

A typical house is supported by beams or rafters in the loft that can easily be identified. Rafters run in circles around the perimeter of the roof, meaning the space underneath is occupied. It is supported by trusses that cross the loft.

Trusses are more expensive to convert because of the structural support that's required in order to replace them.

Additionally, you should also consider the amount of space in the basement below the loft. It would be necessary to construct a staircase in order for the loft conversion to be habitable; this will eat into the existing space below the loft conversion – can you afford to lose this space?
