We fully admit that trying to keep track of every project currently in the planning stages or under construction in Denny Trinagle and South Lake Union is a bit of a fool's errand, but, we decided to give it a shot nonetheless. As best we could, we put together the below map that shows you just how many upcoming projects are going to reshape the neighborhoods, skylines and shape of Seattle. Think of the notable company (Vulcan, Amazon, Touchstone, Trammell Crow, Paul Allen Institute) and they've probably got a building in the works here. Believe it or not, there's still room to add more skyscrapers and towers (and we're sure someone will). There's a decent chance we left out a project or six, so if you see anything notable that's missing, please, let us know.

Mapping Every Major Upcoming Denny Triangle/SLU Project

Tilt49
Touchstone's mixed use development on the half block bordered by Stewart Street, Boren Avenue and Howell Street will include approximately 300K sq. ft. of office space in an 11-story tower, 390K sq. ft. of residential space in a 36-story tower and approximately 600 below-grade parking spaces. A rooftop terrace is planned for the area between the two towers.
Hill7
Touchstone's Hill7 will include an 11-story office building with 300K square feet of space as well as a 14-story Hilton Garden hotel with 222 rooms. There will also be some retail space and 335 underground parking stalls.
1007 Stewart
Trammell Crow's plans for this 21-story tower include nearly 332,400 square feet of office space. They chose to begin building even without pre-leasing any of it. Ballsy.
8th & Howell Hotel Project
The long-gestating project formerly known as Ninth & Stewart is now 8th & Howell. Plans call for 1,270 hotel rooms, 114,000 sq. ft. of meeting and ballroom space, ground-level retail and restaurants and five levels of below-grade parking with approximately 450 stalls and employee support facilities. The 500-foot hotel tower would be tied with 1918 Eighth Avenue as the 13th-tallest buildings in Seattle.
Seattle Times HQ Residential Towers
At 1,945 units, this complex would be the largest residential project in the downtown Seattle area. The project as proposed will include a total of four residential towers over a mixed-use podium – two towers per site. The centerpiece of the development will be the existing 1931 Seattle Times office building which will be restored and incorporated into the development.
Amazon's Downtown Campus
This sprawling four-block (and maybe not done growing) campus now includes nearly 4.1 million square feet of space. They recently added the block bounded by Seventh and Eighth avenues and Bell and Blanchard streets. And please do not forget the massive futuristic spheres planned between 6th Avenue & 7th Avenue and between Blanchard & Lenora streets.
Amazon's 1915 Terry Office
Amazon recently signed a 10-year lease for 1915 Terry Ave., which is owned by Seattle Children’s Research Institute. Amazon will occupy the entire 270,000-square-foot building. Even though the building already exists, a city permit to begin “substantial alterations” means we can expect to see a lot of changes ahead.
Vulcan's Denny Park Complex
Vulcan is still deciding between two options for this project. The first option would break down as 420K sq. ft. of office space in a 240-foot-tall building, 460K sq. ft. of residential units in a 400-foot-tall tower, 30K sq. ft. of street-level retail space along Westlake and Denny, and approximately 800 underground parking spaces. The second option would have about 570K sq. ft. of offices in two buildings, plus 30K sq. ft. of retail along Westlake and Denny, and approximately 600 parking spaces underground. With either option, Vulcan is looking for an alley vacation in order to make it a pedestrian walkway.
Daola Tower
RBF Property Group is planning to build this 42-story tower, which will include a 78-room hotel, 95 condos and 9,600 square feet of retail and restaurant space. The lobby, restaurant, and hotel services will occupy the first and second floors, with hotel rooms on floors three through seven, and residences and residential amenities occupying the building's remaining 35 floors. The building may also include a fitness club, spa, rooftop deck, and a concierge service for both hotel guests and condo residents.
Insignia Towers
The first half of this complex, a 41-story tower which includes a 7th floor terrace that acts as a private park in the sky, is complete and more than 50% sold. The second tower will be done by early 2016.
Crescent Heights Residential Project
Miami-based luxury condo developer Crescent Heights wants in on all this Denny Triangle tower-building action. That's why they just paid $18.5M total to two different sellers on the northwest corner of Minor Avenue and Stewart Street. At just over six-tenths of an acre, the developer plans to turn that lot into either a "high-rise condo or apartment project."
MacFarlane Partners Residential Tower
The plan calls for 328 residential units, five of which will be live/work, as well as 4,717 sq. ft. of retail and below-ground parking for 170 vehicles. The two-story building currently on the lot that is home to City Hardware and Kaufer's Religious Supplies will be demolished.
Stanford Hotels Project
The Stanford Hotels Corp. hotel will include approx. 283 rooms, a conference center, restaurant and roof garden. The total square-footage will top out around 139K. No word yet on the official tenant.
GID's Mixed-Use Tower
When completed in 2015, the 355-unit complex will be directly across the street from the upcoming 3.3-million-square-foot Amazon campus. The building will also come with 4,200 square feet of retail space as well as 242 parking spots.
Sugar Mountain HQ
Sugar Mountain, the parent company behind Beecher's and the Maximus/Minimus food truck, has hired Mallet Construction to renovate a building at 2121 Westlake Ave. Formerly an office building & auto shop, they're adding two floors to the structure, bringing the total to approx. 27K sq. ft. The food company bought the property in 2012 for $4.4M.
Cornish College Dorm Tower
Cornish College of the Arts's new 422-bed residential tower is actually more than the school needs, so they'll be leasing space to City University as well. The building will also include office and classroom spaces.
Compass on Dexter
Opening in Oct. 2014, Compass on Dexter will provide 72 units of affordable housing for families and individuals in South Lake Union, including 54 units for families who are homeless or at risk of homelessness and 18 units for income-qualified households.
