Theater Wit artistic director Jeremy Wechsler says his group’s looking for roommates to help support the space Wit’s taking over from Bailiwick Repertory at the end of this year. Wit, which has a 10-year lease on the building at 1229 W. Belmont, will spend a half-million dollars and the first six months of 2009 on a renovation that’ll yield three theaters of about 100 seats each. Wechsler plans to reopen next fall, and hopes to find three or four other resident companies over the next couple of months. Check out the plan here .
