Such cooperation has been difficult with the currently available spaces, he said.

"This will be a very exciting space for Harvard Square," Orchard said. "It can absorb a lot of talent and energy from a variety of constituents from the undergraduate to the professional level."

Demolition of the theater's interior is already complete. Carr declined to estimate the cost of the project, saying that architectural plans are not yet finished.

College administrators-including Dean of the College Harry R. Lewis '68 and Associate Dean of the College David P. Illingworth '71-said yesterday they were unaware of the construction of Carr's theater.

Alan P. Symonds '69, the technical director for College theater programs, said he had "heard some rumors" about such a theater. According to Symonds, it wouldn't be the first time the building housed a stage: pre-1965, Pi Eta--a fraternity--had a theater in the same building.

Carr plans to offer $1,000 to the person who suggests the best name for the theater.
