Would a builder want to knock down my toilet?

[Gertrudetheadelie]

We have a 1930s house that currently has a lean-to conservatory in line with the old outside toilet and coal store (making them enclosed). If life were the Sims, I'd like to part the conservatory and make a utility and then a larger second lounging area. This second area would have to have a lot of glass as it would provide light to the dining room.

Dilemma is that the indoor toilet needs some work to make it nice (my son found mushrooms!) and the quote isn't cheap. I'm not sure whether to go ahead or not. I'd really like the better toilet but would a builder rip it all out because the pantry and toilet are single skinned if we later decided on this extension work? Ideally, I'd want to keep them as they are in terms of positioning...

All wisdom gratefully received! I've attached a rubbish drawing to make things a bit clearer :-)

So you're just extending the conservatory by 1m and adding a new wall to create a utility? What's the quote? TBH what really needs doing is a full rework of the back section.

@olderbutwiser thanks for replying. Well the builder said that it could mess around 30 thousand because they'd need to dig new foundations for a heavier wall. I don't really want to spend that much and we don't really want to play with the rest of the layout as it works for us. The little toilet quotation is 8 thou and that includes sorting out pipework, moving a water softener, adding a false ceiling with insulation, underfloor heating and all the bits and bobs.

Currently the conservatory is 14'3" x 6'6" (4.34m x 1.98m) so a bloody useless space!

V familiar with the 1930s layout and what I would say, is that not having a downstairs (or second) loo has been the only real “issue”. Completely understand why you are going out from the dining space too, but I would def include a proper loo in your plans.

I'd really like to keep a loo. I suppose the question is, if we went ahead with a utility room and second dining room, would it be that loo? Or would any rebuilding work just knock down the old loo and pantry? I bloody love having a walk in pantry so I'd really rather I could just tag on any work onto the existing structure but my building knowledge doesn't go beyond the Sims...
