What I'm thinking.....Single storey rear extension? this is a great example of how you can use your space. Seperate your kitchen area, but still keep it "open plan" for informal feeling with space for zoning of dining area. large velux windows and floor to ceiling concertina doors brings the outdoors in for those breezy summer days :) Simple. Love.
Create different zones within a larger orangery for a valuable multi-functional family space that can be used for after-school study and play as well as grown-up evening dinner parties. A glass roof creates an illusion of space and height which is accentuated by the use of pale furniture and neutral paint. Run the same flooring across the two zones to create a feeling of continuity
