New Home Construction and Remodeling

A natural extension of our interior design service is collaborating with builders and architects and other home renovation trades. Frequently we are hired by homeowners to advise, help plan and oversee new home construction and home renovation projects. We have vast experience with home building and can work with your architect and builder or we can manage the project for you from the ground up, using trade professionals that we have worked with in the past. In essence, we become your dedicated liaison to the trades and can manage the project from start to finish. We have put our home remodeling and building skills to the test many times by building several Margali and Flynn Signature and Spec Homes.
