Holland Partner Group went under contract on 970 Denny Way back in November and now we get a look at their big plans for the spot that acts as a demarcation between Denny Triangle and South Lake Union. Last night they and Weber Thompson presented their plans to the design review board for early guidance and they showed off renderings for a big boot that will tower over the neighborhood. Including 457 apartment units, 970 Denny is being developed as rental apartments, offering a mix of unit sizes and configurations. Amenities will be located at two levels, the 6th floor and the rooftop. The complex will also include 16,900 sq. ft. of retail in the "foot" and 341 parking stalls underground. The preferred massing model calls for a curved tower scheme with a rectilinear base, which looks the most streamlined of the three options.
