Steve Sierleja, a Certified Green Professional (CGP), first began custom homebuilding in Philadelphia, Pennsylvania in 1973. He moved to San Antonio, Texas in 2003 and formed Custom Homes LTD. With over 300 custom homes under his belt, Steve set out to offer the San Antonio market something different in the way of custom homebuilding.


With quality as his mantra, Steve’s passion is building. He has always believed in the importance of communication, providing the client with the facts as well as giving them realistic expectations from the beginning. When you build with Custom Homes LTD, Steve is the field supervisor. Steve does not use superintendents. He feels that he can better maintain the quality of your home by personally overseeing every phase of the construction.


In recognition of quality, unique design and quality construction, Custom Homes LTD received the 2006 Award of Excellence from the National Association of Home Builders.


Custom Homes LTD can build with steel and wood studs as well, and still achieve a high performance home. Steve is also a Master Distributor of BuildBlock Insulating Concrete Forms (ICFs), which is an affordable beginning to an energy efficient home.
