Swinerton to build Dunn Lumber's Latona Station office-lab project

Real Estate Editor

Looking south, the project would replace some old buildings east of the main business (the low-slung building at right, with white roof).

Permits for demolition, excavation and shoring are near on Dunn Lumber's less used east block (not the main operation on its west block). There, at 3800 Latona Ave. N.E., the planned Latona Station office and lab project is moving closer to a possible start next year. The mass timber building, designed by Weber Thompson, recently received its SEPA determination of non-significance from the city, an important last step before securing a master use permit.

At the same time, the Latona Station team is now drawing into focus. GeoEngineers, Malcolm Drilling, Ground Support and KPFF Consulting Engineers are planning the demolition and site prep that would precede above-ground work. Swinerton Construction, which has a mass timber specialty division, is now indicated as the likely general contractor.

Hess Callahan Partners and Mark Grey of Stephen C. Grey & Associates are developing Latona Station with the Dunn family. No broker appears to be attached to the project.

The family owns the land, and the business will perhaps occupy some of the offices in a building to rise three and four stories above its north aspect. That faces the Burke-Gilman Trail and Northeast Pacific Street. To the south, on a sloping site, Latona Station will rise five stories above Northeast Northlake Way.

The lower concrete portion of the building will include about 23,212 square feet of warehouse space, along with 166 parking stalls on three levels — both structured and below grade. Some will feature EV charging. About 156 tenant bike stalls are also planned.

The offices above will total about 145,554 square feet. Almost 4,100 square feet is programmed as retail and restaurant space. Some of the latter would face north to the office entry plaza and trail; another restaurant bay would face would face south to Lake Union.

The team also includes DCI, structural engineer; KPFF, surveyor and civil engineer; RDH Building Science, envelope; and Glumac, MEP and sustainability. Weber Thompson is also the landscape architect.

Seattle Art Source is also consulting on a public mural to draw inspiration from Lake Union's industrial past, the lumberyard itself and modern mass timber construction.

The project will pursue LEED gold and Fitwel certification. The structural mass timber elements will evidently be both CLT (cross-laminated timber) and glue-laminated Douglas fir. Latona Station will divide its bulk into east and west wings, with a walkway and view corridor leading to another plaza and stairs down to Northlake. Rooftop solar panels and a fourth-floor terrace are also indicated.

Weber Thompson estimates the total project size at around 275,000 square feet, with the Mandatory Housing Affordability fee still not calculated. The project has passed through design review.
