Renewal and re-use of existing buildings is central for sustainable urban development. When we can keep our architectural heritage as a vibrant and integral part of our lives, we are able to keep a sense of who we are; and when we can repair and preserve our surroundings we make the most efficient use of our natural resources. We have completed a number of heritage restoration projects working with best practices for material compatibility and historic construction. We have received numerous awards for our heritage restoration work. Also, a significant number of our projects have been re-purposing and up-grading of more recent buildings for new technologies and uses.
