A fire destroyed St. Paul's Church in Brookline, MA -- an English Gothic-styled church designed by Richard Upjohn in 1851. We were contracted to design the rebuilding of this historic landmark to allow greater flexibility in the uses of the church. The interior now serves as a multi-purpose space: while the main use is for worship services, other uses include concerts, lectures, and plays. A major feature of the new church is an active solar heating system which provides more than 80 percent of the building's heating needs. The exterior of the building closely follows the lines of the old church except for an addition of two light scoops high on the roof. Subsequent to the initial rebuilding, we designed a sacristy, liturgical furnishings, and renovations to make the building fully accessible.
