Also have a dual purpose room. We did inexpensive white shelving units around two walls, with fabric boxes to stash stuff, (office, and my "crafty" supplies), threw in a few decorative items. Got a tall basket for rolled up mats/foam roller storage, a complementary lower basket to throw in the requisite elastic bands, small hand weights, etc. Decorated walls with pics from our travels, framed with colored mats.

Sorry, I don't know how to load a photo, but the finished tiles look just like the Ladbroke Trc pavers above only it was done with poured, coloured concrete and then cut and grouted to make it look like pavers, hence no weeds ever! We had it done a terracotta colour which looks great. The sides were done as a wooden retaining wall with stairs up to the higher level of lawn, also done in the concrete. The advantage of concrete opposed to decking is that you never have to think about again as it doesn't rot like decking does after a few years and have to be replaced. It make cost a little more initially, but long term it's really worth the money. We finished off the top of the retaining wall with buxus hedging, but you could put flowers or whatever you fancied there. The concrete trucks have long hoses which can pump the concrete a long distance to the back of your house so no worries there. Hope that helps. Good luck.

I've had a think too (thanks to your thoughts @caitlinfurby). Would it work if the bath went down the end beneath the window (handbasin/end of bath currently there). The toilet stays where it is but the wall reduced to a pony wall. The linen cupboard on the right hand side as you enter the bathroom is removed, as is my sons bedroom wardrobe (a new wardrobe for his room can go on the wall in his room against the hallway). That new space is turned into a walk in shower. The cupboard on the left hand side can be widened a bit at that current entrance way to make a new linen cupboard. Around the corner from that, opposite the toilet could be where the handbasin goes or in between the bath and shower? The door can be a pocket/cavity door or just a barn style door to enter the bathroom off the hallway. The current door to the kitchen is actually hinged the other than the plans show but we could just re hinge it the same as the plans show. The first little box area on the plans to the right as you enter the kitchen will have to stay as that is where the fridge is. The window at the end of the bathroom is close to going all the length of the wall...don't really want window sill getting wet from shower hence why maybe bath could go there. Husband wants to have a separate bath and shower. Do you think these ideas could work? Means the plumbing can pretty much stay as where it is too. What to you think??

Hi siriuskey. Not sure how to place the furniture yet. Still trying to work it out.. I am selling my dining table and chairs. My new chairs just arrived today.
