To get your children excited about the new house, make room plans. You don't have to limit yourself to their rooms only. If they're interested in helping arrange and decorate other rooms in the house, let them. Take a trip to the hardware store to look at paint swatches. If you're going to purchase new furniture and the kids are interested, take them with you. For teenagers, set a budget and let them tackle their own rooms -- picking out colors, linens, rugs and furniture. Encourage them to shop at consignment and thrift stores. For younger kids, you can set a budget and work with them on executing their vision. Then, when it's all done, you can invite some family or friends over for a "big reveal" like they do on TV shows.
