Hi there- Lovely place it seems you've got. I have two suggestions for you. Firsrt, if this is within your budget, I would try to move the Bath and WC over next to the master bedroom - right where the eat-in section of the current kitchen is. Then, you could extend your kitchen into the area where the bath and WC used to be, and it would be open to the drawing room. Alternatively, if that is not in the budget (that plan would require a lot of plumbing rerouting) then I would take down the little wall that closes off the kitchen and the little wall that extends the drawing room by the WC and bath. By simply removing those few sections you'll open up a lot more space!

Well for windows and doors you'd use gloss or satin finish paint in white and it shouldn't really be different to your white wall paint in colour , if you used the same shade of white from the same company.

Looks like some of them open...it would be cool to get some glass paint and paint the windows to look like stained glass...just pick you favorite colors and go at it

You can have bigger windows in your drawing room. The size can be 6'x6' on both the sides. The sill level can be at 2' if you like bay windows. Add one more window in your dining room. For the bedroom, you'll have to make the furniture plan first .For all the toilets, there must be ventilation at the height of 7' and the height of the ventilation can be 18". In the kitchen its the same as bedroom, you'll have to do the plan first. For more detail planning you can contact me at rupalgshah@hotmail.com.
