There are few websites created in the last 20 years that have made a bigger impact on the construction and remodeling industry than Houzz. For consumers, it has lots of tools for dreaming about a beautiful kitchen or bath. You can look through hundreds of real world ideas and products, all filtered to your own tastes. You can save the ideas you love, realizing and refining your tastes. If (when) you are ready to take that next step, you can find professionals in your area - sometimes right in the projects you saved! - and share your saved ideas with them to be sure they understand what you want.
For remodelers and construction companies, as well as other tradespeople, Houzz really helps get the message out to interested customers: who are you, what do you do, what have you already done well and what they can expect when they do business with you. And the customers that contact a remodeler are more knowledgeable and further along in the process of decision making.
In short, Houzz has been a great resource for both customers and remodelers in a time when most websites are pushing products and sales without fostering relationships - and relationships are ultimately what are needed in building or rebuilding your home!
