When it was completed in 1893, the Monadnock was the world's largest office building. People are still startled by the power and simplicity of its design; some say that modern architecture began with its sweeping curves. The restoration of the Monadnock is a nationally acclaimed melding of historic character and modern technology. The building’s 300 suites are ideal for independent professional firms and entrepreneurs. They range in size from 250 to 5000 square feet, so businesses can grow here without relocating.
