Lights which automatically turn on when I enter a room (especially in the kitchen and in the hallway from the bedroom to the bathroom) and lights inside my wardrobes (especially inside the one in the bedroom: I often get up earlier than my hubby, and it may be still dark outside, and I don't want to wake him up while I'm looking for my stockings).

Hi Cynthia 1. agreed ... although I would just raise the small concern that this will be a large master bedroom which we hope will be impressive and attractive on any future sale. Therefore we would like to avoid as far as possible, anything which makes one end of the room look a bit unusual (i.e. one obscured window not matching other clear windows). I am hoping we can come up with some internal (or possibly even external) design idea to mitigate the actual difference in window glass. One idea has been to use folding plantation shutters for example and to have the top 1/3 of windows (above the 1.7m threshold) as openable. However given the windows are dormer, the top 1/3 has the sloping roof, so cannot fit in plantation shutters around the top 1/3. 2. agreed again ... but again for future use by other occupants, it may seem strange to have a room with only obscured glass (or at least the main window pane up to 1.7m). Wondering if there are any design ideas which can make it look more like a normal room even though 3/4 of the window pane will be obscured. 3. that could be possible, I was thinking it would be a problem since the size matched (as usually I've seen the staircase window when stained glass being of a totally independent size and shape and therefore one does not even expect it to match, as it is unique in every way). However, here it is not only the same size and shape but also part of a horizontal row of windows, so I would think maybe the eye would expect matching styles across the plane? Would love to see a photo of exterior of a house where one of the windows in a row of similar sized windows is stained, if anyone can share? 4. The last window will continue to have regular glass as is it part of existing (pre-renovation) house and in any case (although difficult to see from drawing) set back from the 3 new windows by about 2m (you can see a flat roof in front of it). Therefore less of a need to imagine it would match as it is on a slightly different plane to the other three. Will definitely consider Solatubes for the study room ... hoping this is not another planning authority approval issue!

Thanks again for all your comments. Particularly helpful to be alerted to socket issue. I took these pics before the builder replaced the sockets with some nice chrome ones. (see new pics) However, he's still got them in the wrong place. Will raise that today. He hasn't actually finished the hood area in these pictures - as I stopped him. But also the chimney extractor doesn't seem to be functioning so it needs to come down anyway. This solves this problem and we can tile behind it - although I'm still worried that he's not going to be able to redo the job well enough. I've added some more pics with better light. Still finishing the floor and just have to adjust and tweak a few things but (apart from tiling) nearly there! The kitchen is Howdens Burford Grey, Pure White Quartz from Master Quartz (not been impressed with this as marking so easily with pans, belt buckles, any kind of grime - but probably shouldn't have chosen white! - anyone else had problems with their quartz?), Paint mainly F&B Wimborne White and Slipper Satin woodwork, engineered oak floor from Howdens.

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.
