Imagine a huge map of downtown Summit, 30 by 20 feet, that features all of  the streets and dozens of significant buildings, and then envision teams of children and their  parents, having a wonderful experience creating each of these treasured buildings using  more than 60,000 Lego blocks on a gymnasium floor.

On Sunday, January 30, from 2:30 to 4:30 p.m., the largest LEGO construction project ever built in Summit, benefiting the Summit Historical Society, will be held at Washington School, 507 Morris Ave. The Architectural Heritage Workshop is intended as a fun way to teach children, their parents and grandparents — even aunts, uncles and cousins — about the heritage of buildings in Summit.

The workshop will be presented for the fifth year by Stephen W. Schwartz, AIA, Architect of SWS Architects, Livingston, New Jersey with the help of Summit Downtown, Inc. and Coldwell Banker who is sponsoring the workshop. Register for the event in person at Coldwell Banker at 401 Springfield Avenue starting January 13, 2011. The registration fee is a minimum contribution of $25 per family, payable by check to the Summit Historical Society. Payment must be made at the time of registration to secure a spot at the event, which is limited to the first 50 families who register.

Children must accompany their parents for the workshop, and spectators are invited to join the fun at no charge.
