Can a timber cabin be used as a permanent dwelling?

Yes, but it must meet full Building Regulations for dwellings including: structural design to Eurocodes, thermal performance to Part L, fire safety to Part B (including means of escape, fire detection, and structural fire resistance), ventilation to Part F, sound insulation to Part E (if attached), accessibility to Part M, and drainage to Part H. A timber cabin designed as a permanent dwelling is essentially a small timber-frame house and should be specified accordingly.
