A major renovation is very expensive and would include changing multiple facets of your kitchen. A major renovation could include your cabinets, the layout of your kitchen, new appliances or windows. A contractor or subcontractor is usually needed to handle the arrangements if your modernization includes wall movement. You may be able to hire a project coordinator from a home improvement store to handle the details if you do it yourself and buy the supplies from them. Don't undertake a major renovation without a plan in mind.
This book will help you guide on the things you have to do in your home.
