We have a 3 bedroom Victorian terrace, layout basically identical to this one I found on Pinterest. We have a DS and a DD, 3 and 1. In future when they’re older will probably need a (live in) au pair.
At the moment we are in the master bedroom at the front, kids share middle bedroom, spare room at the back. We are planning a loft conversion.
I’d prefer to stay in the master bedroom. When they’re older one of them can move into the back room so they have their own room, and the loft can be 2 rooms: one office/spare room and one for guests/au pair, with separate bathroom up there. I think it’s nice to be on the same floor as them and for visitors to be separate. Also the master bedroom is a lot bigger than bedroom 2 so I think it would be unfair for one child to have it.
DH on the other hand thinks we should do a master suite in the loft. Kids can share for now and the master can become a big playroom now, room for one of them later. Guests/au pair can have the back bedroom which is still fairly separate from other rooms. They’d all have to share a bathroom though.
Which is better for (a) family life and (b) house value? No plans to move any time soon but wouldn’t rule it out in future.
NB photo is from Pinterest - we haven’t done loft yet so it’s just ground and first floor in our house.
