Thank you for the pointer, some really nice lighting solutions on that site :). In fact I'd sketched the idea I wanted but for some reason the PDF with my sketch didn't upload with the other 2 images. Tried it again just now. Can't see anything anywhere like the this rounded half ball design

It's tough without photos or plans. I prefer to put outlets in the baseboards they are unobtrusive when not in use. Make sure switches are closer to door frames and not in the middle of a small space of wall. For a floor outlet. Lay out how you would have furniture in the room and plan floor outlets to be under a chair or sofa. Be sure to have switched outlets in areas where you may want a lamp to be turned on easily. Dimmers everywhere. Think where you would want switched lighting. Think about how you would use the entire space...where you would have furniture, electronics, lamp lights. Be sure to have outlets for a major electronic bank (such as TV etc.) (computers, printers, other electronics) in these areas, be sure they are on a separate circuits and nothing else is on these circuits. Put yourself in the house with all its furnishings and see how it all works...this is how it makes it all easier. Be sure cold air returns are not in the middle of ceilings or walls in major rooms, try to have them located to unobtrusive areas (halls & walkways & between spaces). Don't let them tell you they cannot. We designed our home, did the entire electrical plan, and we were the general contractor. Because we planned so well the process went smoothly. And we never had a "why didn't I think to do something different" moment.

Hi, I am building my house and have seen really nice and somewhat expensive light switches. Now I cannot afford matching plug sockets but was wondering if it mattered? IE, copper type switches and a more standard white plug sockets? Thanks

Another option that I was thinking of, knock the internal glass walls of the conservatory and make the hall smaller - this leaves a very large open plan space (9m x 6.4m) but I have no idea how best a space like this could be used?? Can anyone give me their thoughts here? Need to move if I am to make an offer
