Would like to design some things? Or you just want to get some good ideas from here. In my point of view, I recommend finding a professional designer for what you want such as renovation. They may give you more reasonable advice within your budget. However, you also need to know what’s going on. For example, if you want to do interior 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.
