Dear all, If you want to add a bathroom, you have to start there and work everything else round it. The reason for this being that you usually have to feed into the existing soil pipe. The soil pipe in this case is on the left hand outside wall. Without knowing if you can put another one on another outside wall ie the rear, which is probably unlikely, you have no option but to place a bathroom as close to the entrance on the left as possible. Obviously you could change the system in the new bathroom to a macerator style toilet, and technology has come a long way with regards those, but they are not for everyone. It may be possible to change the shape of the kitchen, remove the back entrance and push the front wall back, ( maybe not, as i presume it's instrumental in holding up the mezzanine ) If it were possible in theory:- You could - move the kitchen wall back to make more room in the lounge. Add a bathroom with pocket doors ahead of you when you come in and split the lounge down the middle. You could also have a pocket door entrance from the bedroom to the bathroom jack and jill style. That bedroom would also get the balcony.

That is a truly superb transformation - a great demonstration of what can be achieved. Everybody will now want one! Well done on some excellent work!

Hi, We had a feature corner window in our design. Originally it was meant to be a custom glass unit just as the one shown with a cantilever beam. However, the cost of the glazing ate into our budget and would have compromised on something else. Anyway, we went for two separate standard units with a corner post (take a bit of weight but more to join the units together). This worked out much cheaper and still gave us the finish we are happy with. Think it was around £1450 compared to quoted prices of £5000-6000. The builder was reluctant also, but if its in the plans (steel calculations) and they have quoted for it then there should be no issue!. Just having a second look at your plans, the one I would be worried about is the run of glazing (opposite your patio doors). A cantilever beam needs to be much more than the length of the run you are showing from what I understand of engineering. So not sure how they architect/structural engineer have accounted for that!....from my experience. Architects can sometimes get carried away with a design without thought about such practicalities. I would go back and question this design element...Builders vs architects!

That's lovely
