Front or back?

A strange thing has happened to our house. The back has become the front. Or, to be more accurate, the back is becoming the front. This is most disconcerting, especially for someone who has poor depth perception and issues with recalling where she is at any one time.
The house still has its (horrible glass but very obvious) front door, with a (weedy) path leading directly to it from a (rusty and squeaky) gate that opens on to the pavement. There is also a door at the back of the house. This was previously seldom used by anyone but ourselves, but is now used by friends who know we generally can't hear knocking at the front. (Mem to self: get Mr W to fit a doorbell.)
We have a perfectly nice front room - comfy sofas, cushions, fireplace, telly; all the normal accoutrements. It's not very often used because it tends to be cold and we rarely watch telly. There are also, in this house of wonders, three bedrooms and a loft room latterly inhabited by LF3. No problem so far. Or so you'd think.
The house is plenty large enough for five, meaning this middled aged, empty nester couple rattle around in it horribly. Our plan has been to, I think the current term is, repurpose some of the rooms. Viz: the back bedroom, which gets all the sun and is the warmest room in the house, has become a joint drying room/study/Spare Oom. Part of this repurposing is to detach the LF from 'their' bedrooms, mainly because they tend to all come at the same time and squabble over the one double bed which is located in what Malin thinks of as his room.
What the repurposing means is that Mr W and I have trouble in naming any of the upstairs rooms. Is the little front room 'the little front room' or 'the fridge' or 'Izzys room'? Is the back bedroom 'the back bedroom', 'the study', 'the drying room', 'Ellys room' or even 'Izzys room' (since she was the last occupant)? Luckily the loft has become simply the top room - at least to me.
However, I guess the main reason for the shift in orientation of the house is the fact that we (well, alright then, me) spend all our time in the back room which has become the front-er-back room. Thus the back bedroom becomes the front bedroom as it is located over the front-er-back room, which causes terrific confusion because the front bedroom remains the front bedroom.

Christ, are you as bored and confused as me? Probably.
Therefore; the Director of Operations is signing off from the special DOA seat on the sofa in the front-er-back room.
