@embzop, I would keep the guest bedroom as plain and neutral as possible. And keep it decluttered to keep it inviting. @Tom Flannagan, I think bathrooms are just that one space in the house that is not attached to any other room style wise. When I walk into my future bathroom I want to be swept away from this world into another one of luxury and serenity! I don't care about styles and 'what should fit the house', the bathroom is my space and I will do with it what I like :) @milicaopica, I think there are great options when you have a 5m high ceiling! When you put in another 'floor' you can have extra storage, a hide away, extra sleeping space, perhaps a slide? The possibilities are almost limitless! @k11agl, I get your point. Possibly you could build a wardrobe against one of the sloping walls. But that of course depends on how much ground space the room will have left over and what you want to use the room for. I've got sort of the same problem next to my dormer windows, but I also have radiators up against two of the vertical walls. No wardrobe here :(. I think hallways are tricky too. They need to be functional yet inviting. Fortunately I have two; one tiled and the other one is going to have a parquet floor. So the first one will be the 'mudroom' where the kids can dump their stuff and coats and it will be made to be easily cleaned. The second, bigger one will be the 'nice' hall, with fancy wallpaper and nice furniture (telephone seat). Thinking about it I realise how lucky I am to be able to have two hallways with different functions ;)

Hi. in terms of interiors I would guess people would like to understand how to identify and mix undertones, what colours to use depending on the light in the room, what proportion of colours to use in a room and how to make the house flow etc. On the flip side if you opt for neutrals how do you get a scheme to work. I'm sure I'm not alone in that the colours I wear are definitely not the colours I would use in my home so although clothes are based on what would complement your eyes, skin tone, hair colour, figure etc how does that translate into interiors (although there is a proportion of black in both :) )

Epoxy/Resin is a much better solution. It is flexible and not brittle so it doesn't break and fall out. It sticks to the slabs so you don't end up with gaps caused by expansion. I haven't used it personally but have seen it on a neighbours front garden. https://www.youtube.com/watch?v=Jpsgca52PFQ You will need to remove all the soil that's filled the gaps first.

I think the extension would give you the most sociable space for the kitchen/diner. A linear kitchen along the right wall with a pantry/utilty near the entrance, (if you could swap the wc and utility/pantry over maybe). With a corner dining area to the left and a chair by the patio doors. The skylights would be above the table and chair. Then you could reinstate the wall to create a hallway by the dining room, opening up the dining room to the front reception and have patio doors overlooking the garden and create a library reading/drinks/card games area. I think if you put the kitchen in the dining room the front room would need to be the dining space and the extension the sitting room with a log burner or similar?
