The south tower of the Insignia condominium project in Belltown is now officially over 50% sold. With 350 units, that means they have around 175 units in contract.
As for the construction of the 41 story tower, it has topped out on the south tower and the north tower is now coming up. The south tower should be ready to start closing in spring of 2015.
For hard hat tours, once you have signed a reservation you will be allowed into the building for a hard hat tour so you can see the space in person.
