If your site is able to be developed, you have probably already begun to think about whether your existing space suits the way you live/work and how you might want to change things. Have you seen something similar before in a home furnishing or building magazine or at a friend or neighbour's house? Try keeping a scrapbook of ideas as you start gathering your thoughts, perhaps from magazines or web sites like Pinterest. Think about why you have chosen each image -is it the overall effect you are looking for, or is it to focus a single item, shape or colour that you like?
