What is an HMO Conversion?

Physically, an HMO conversion is about maximising the habitable space of a building intended to be used as an GMO. While a family wants open-plan spaces and large gardens, an HMO investor wants to create as many high-quality private units (bedrooms) as possible while maintaining a functional communal space.

An HMO conversion typically involves work such as rear or side extensions to create large communal kitchen-diners, dormer loft conversions to maximise bedroom counts, large reception rooms partitioned into private living units and more.
