Our family holiday house has a non-compliant internal stair. Timber House was originally built on stilts and the ground floor bricked in later.
We have recently replaced the external stair and this is compliant with BCA, but has open treads and some don’t like using it.
Living and kitchen are at north end of house with views. Sliding door from living to balcony. The upper side door is not really used. Ground floor the front door is on side of house under car port. Windows shown on west elevation at ground floor don’t exist.
Kitchen was redone 10-15 years ago, flat pack and island bench is not fixed to floor. Hws that was at top of stairs has gone outside and space converted to kitchen pantry.
