Create zones. In an age of open-plan living, it may not be immediately obvious how to accommodate a new person with their own timetable and social life. Clever zoning is key. Consider how you could rearrange your communal space so it will comfortably accommodate multiple activities and inhabitants working, resting, eating or cooking in harmony.
Look out for small-scale furniture if space is tight — lots of brands now have a dedicated range of compact or flexible pieces. And shop creatively — a small round metal garden table can easily double as an affordable dining or laptop spot for one. Comfy armchairs are good, too, since you may not always feel like sharing the sofa.

Create the ultimate bedroom. If communal space is very limited, it could be worth moving out of the best room in the house and turning it into a luxurious, multi-use space for your housemate. Make it somewhere he or she will want to hang out. Consider how you could incorporate a TV (in the end of the bed, as here?), a desk, a lounging area and even an en-suite or kitchenette.
