As trusted builders in Cardiff, we deliver end-to-end solutions that maximise rental yield, ensure legal compliance, and reduce long-term maintenance headaches.
What is a HMO?
A HMO (House in Multiple Occupation) is a residential property occupied by three or more people from different households who share facilities such as a kitchen, bathroom, or toilet.
HMOs are popular with landlords due to their strong rental returns, but they also come with strict legal, safety, and licensing requirements.
That’s where AJ Construction comes in.
