Supervintagegirl- have you every seen or read about "Extreme Irining" as a sport? There are World Championships in it. Got a book on it as a fun wedding present for a cousin who has been known to ask you to take of some item of clothing that you are wearing as you stand in front of her so she can iron it for you!! I kid you not .... My SIL not far behind. Spent 4hrs - FOUR FULL HOURS - Irining her 20 something year olds shirts the other evening !!! It would take less time to train them to do their own. Ho hum .... ironing can be very therapeutic tho ....

If you were our client, we would first assess which way the house faces in order to understand the direction of the sun and the likely impact on the space in terms of light and heat, plus we would ask what use you intend to place on the new space. It is also the case that with whatever heating - a fully glazed conservatory can seem an inhospitable space in the winter months. Even in the UK heat gain during our short summer is a major consideration and whilst roof blinds can be added - these can spoil the original design intent. A part solid / part glazed roof with fully glazed walls may be the most successful. Attached image of a garden room with a large strategically placed roof light and two fully glazed walls.

When we extended our house last year with a large fireplace we wanted a multi fuel burning stove. However the regulations regarding flue and chimney meant the neighbours would have been subjected (and may have objected) to this eyesore, even if at the back of the house. We settled for a Gas version. The stove itself (Huntington) looks exactly the same as the multi fuel version. However, we are really delighted with it. The flame looks really genuine and as others have stated there is no cleaning out and we have instant heat and sometimes so much output that we no longer have to turn on the central heating in the lower rooms! A real success. (Awaiting our first gas bill however).

Re C: Sorry to throw another idea your way, but there is another way to set out the storage in C. Rather than have the cupboards/wardrobes opposite the bed, you could dedicate the space under the sloping roof to the cupboard/wardrobe. ie there would be a long row of storage running parallel to the bed. (I've had this in one of my houses). To look at the wardrobe doors look square. The pitched room is hidden behind. The advantage is that you can then have sliding doors on the wardrobe, and a long hanging rail. It's only a half height -- so not good for dresses, full length coats - but fine for shirts, skirts, suits etc. This leaves the wall opposite the bed (in orientation C) free for drawers (maybe two sets of drawers - if two people are using the room) and you can display photos/vases/ etc attractively on the surface of the drawers. Maybe put art work/photos above the drawers (which you can look at from the bed), or wall paper the entire wall. So - you get a long row of hanging space (behind neat sliding drawers), you can store stuff behind and below your hanging space (because the eaves go back further), you have plenty of space for proper drawers, and you look at an attractive wall when you walk into the room. (Disadvantage - not much full height hanging space - you could add some but not alot behind the door)
