You may be able to get this made to order from a window and door company. You can have cat / dog flaps fitted in glass, it doesn't have to be wood. We have one for our dogs, you order the flap, give it to the door company and they order it with the hole needed for the flap, which you then fit. I can't see why they couldn't put an openable window in it. If you're set on wood, then i'd just get a carpenter to make a window to fit the door and then re-glaze the portion underneath. I once put a stained glass window in a front door, if it's wood it's a lot easier to make all sorts.

I’ve always been a fan or greens and blues, but lately I’ve been loving yellow in all its hues, just as colourhappy has suggested. What could be cosier? It goes beautifully with other shades too as well as simple whites. I rather like F&B Hay too. As far as the desk goes, you can get desks in a cupboard rather like the old fashioned, but beautiful, bureaus, if you decide on an office there. The fact that everything is shut away at the end of the day, keeps everything tidy. I do rather like the idea of a drinks area! Here’s some ideas which you may love, or not, as you please.

I would, in no small way, be miffed that the architects incorporated a communal space without first checking they could! A basic oversight. I agree with Kingfisher. If this is a short term fix, meaning you don’t want to spend too much, then moving the staircase for such little gain seems to be throwing good money away. It looks like you could still have just about everything you require without moving the staircase. When I say just about I mean not to have an en-suite (you mention it but I cannot see it on your plan). On the lower ground you have room for the master bedroom and nursery with one bathroom. Your proposal to build a wall to make the nursery smaller, thereby continuing the corridor to the door, solves your cat flap problem and can still be done with the stairs where there are. I agree that you should remove that internal door and small wall in the hall. It would open out the space and let in more light. On the raised ground level again your plan is good and can be achieved whilst leaving the stairs well alone. You have indicated that you want the study to also serve as a third bedroom. I imagine this is for occasional guests so would primarily be a study. Have you heard of Murphy beds?They are an ingenious way to utilise your space to its fullest where the bed is stored vertically inside a cupboard. studybed.com is just one site of many that offer other combinations of transformational furniture. The studybed is a desk that folds out into a bed. That leaves your good proposal to convert the living room into the kitchen/living room and yes I would move the front door.

We used to own an old farm-worker's cottage with a separate, single storey coal/laundry building behind. We connected the two buildings with a rear hallway link building and gutted the coal/laundry shed to convert it into a new kitchen. We removed the old ceiling, put veluxes in the roof to add light and also kept a few of the joists (we removed some of them but had to put strong bolts through the remaining ones to tie them to the rafters.) We also put collar-ties on some of the other rafters and put extra reinforcements in along the wall-plate. Bottom line, is, I think it's well worth opening up the room into the roof pitch – it will look fabulous – but you should probably have a word with a good structural engineer first! :-)
