Seattle-based Martin Selig Real Estate hosted a re-groundbreaking ceremony Wednesday afternoon to celebrate the restart of construction on the 400 Westlake project, which will be one of the world’s greenest buildings when finished.

Construction resumed on 400 Westlake, a 15-story office building planned for South Lake Union, on Sept. 14. The project is Martin Selig Real Estates first property in South Lake Union. Construction teams from Lease Crutcher Lewis first broke ground on 400 Westlake mid-February, but stopped on June 19 so Martin Selig Real Estate could evaluate the coronavirus pandemic’s effect on the future economy.

Were expanding into Ballard and South Lake Union for the first time, as a way of diversifying our portfolio, says Martin Selig Executive Vice President Jordan Selig, who has long championed the project. Were excited to introduce our product to the neighborhood.

The projects, which is on the site of the old Firestone building, is planned to be finished in spring of 2022. The building will have around 230,000 square feet of office and 9,000 square feet of ground-level retail space.

It will be the largest green building of its size, using 75% less energy consumption than the 2012 Seattle Energy Code, according to Martin Selig Real Estate. Building water will be recycled for non-potable water uses, and the triple-glazed exterior windows will increase insulation.

The building will also have two floors of indoor parking, on-site shower facilities, pet-friendly offices and bike storage.
