The Architectural Control Committee's purpose is to enforce and protect the design standards and restrictions set forth in the Greentrees Village Declaration, Bylaws and Rules and Regulations, and to protect the rights of both the individual property owners and the community. No lot construction or improvements to the exterior of homes or buildings or the existing structures can be altered in any way so as to affect the exterior portion of any structure on a lot, unless such improvements are approved by the Architectural Control Committee.
