An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Landlords in Stratford (E15) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have. Stratford has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
