Block 103

Portland, Oregon

Located at the southeast corner of the Oregon Square development, Block 103 will be a thirty-story apartment tower with ground floor retail. The 347 unit building will complement the Lloyd District’s distinctive modern roots with a more contemporary approach. The design breaks up the form into modules of curtainwall, which strive to exploit the slender verticality of the form. Standing at 325 feet tall, it will be the tallest building within the district.

The sculpted form maximizes solar exposure of the plaza and takes advantage of sweeping views to the mountains, city, river and neighborhood between existing buildings. The building diagram and profile of the floorplans are generated by two overlapping parallelograms that respond to a 10 degree cut to maximize solar access for the plaza. The building mass is broken down into four story modules, which help to scale the building and develop a simple and platonic expression consistent with the vernacular of the existing buildings in the district.

Following the successful Hassalo on Eighth development directly to the north, Block 103 will strive to achieve aggressive sustainability goals that include water reclamation and re-use, energy reduction with an emphasis on natural light and fresh air for residents. It is on target to achieve a LEED Platinum rating from the United States Green Building Council. The project strives to elevate the residential options to the eastside while following the aspirations of the Lloyd Eco District.
