Would like to design your house? Or you just want to get some good ideas from here. In my point of view, I recommend finding a professional designer for your places. They may give you more reasonable advice within your budget. However, you also need to know what’s going on. From the design, you also need a plan. The places you would like to reorganised and the requirements including function addition should be listed. You should also control your budget. DIY is impressive in some places, but you need to consider carefully as it has a high risk of failure.
