The top contract of the past week took place at The Benson, where the tenth and eleventh floors were asking $27,950,000. Buyer’s broker Bo Poulsen of Brown Harris Stevens said the buyers were originally looking for a townhouse, but “it offered a lifestyle you couldn’t get in a townhouse.” Developer Naftali Group is combining the units into a massive duplex, and the buyer is paying the sponsor for the extra construction costs.
