A commercial to HMO conversion turns space that was never a home, such as upper floors over shops or small office buildings, into shared accommodation. For a house in Coleraine we start with a measured survey, check the NI HMO standards and licence conditions for the number of sharers, and then price each item separately. With students as well as working sharers renting in Coleraine, we plan bigger jobs for the gap between academic-year tenancies where we can.

- A licence is needed where 3 or more people forming more than two households live as their main home and pay rent; the NI HMO Unit at Belfast City Council licenses for every council.
