If furniture is all against walls a room will tend to have a flat, square, uninviting appearance. Even when placing a sofa "on the wall" you would want 3" inches space so the sofa won't rub the wall. The important thing is that furniture groupings facilitate conversation. Try moving your sofa out from the wall, if you don't like it, you can always move it back. :D Best wishes!

Hi Rahul Satija To answer your question, regarding which material to use for the outsides of your home Terracotta Brick - unless you have used bricks that are meant to be left exposed, ordinary bricks will take in a lot of water and leave the walls damp, and hence not a great idea. You could ofcourse cover it with a veneer of brick cladding but that is something we would not propose. Between wooden cladding and paint, it frankly depends completely on your budget. Wooden cladding looks extremely good but is quite pricey. Our suggestion would be to paint the majority of the home, with highlights in parts in wooden cladding.

A hob and a separate oven will be better as you can get storage below the hob

sararahim123 What constitutes an adequate illumination level varies from person to person. What exactly do you require illuminated? If its simply ambient light you would have tiny lights as shown that throw light on the stairs itself. If a bit more is required you could consider adding a railing with a light under. If general illumination is what you are going after, but in a muted way, would suggest wall scones that throw light upwards onto the ceiling, diffusing the light.
