A master plan was prepared to assist the Lancaster, Pennsylvania congregation in implementing a renovation and expansion program to support the growing needs of their congregation. Following the completion of the Master Plan, additions and renovation were constructed, including a 48,000 sq. ft. addition incorporating a 1,200-seat Sanctuary, youth and adult education classrooms, multi-purpose room, library, offices and other ancillary spaces. The Sanctuary Building was designed in the spirit of Puritan New England meetinghouses of the 17th and 18th centuries, with which this congregation identifies.
