There is no harm in feeling the need for something different when you have lived in your home for a number of years. However, the problem may not be the area, which you are likely to be extremely fond of. Instead, the problem may be that you have grown tired of the same old interiors and you feel the need for something more modern and exciting.
Of course, modern does not mean cold and sparse. Modern interiors can be just as warm and comfortable as traditional interiors; they just achieve these things using a different style. It is still all about getting the right kind of light in the room and softening your interiors so that they are really appealing and inviting.
You do not even have to be drastic in the changes you make at home, but if you want to renovate on any significant level then getting the professionals involved is the only way to go about it. If you talk to an experienced project manager about the comfortable modern interiors that make up your vision for your home, then they can get the design team to work on getting you there.
