Move the House Takes Shape

by Jason King

Lots of activity on the Move the House project, as artwork and landscaping along with final site elements come together.  The sidewalk has been poured, and street trees installed, green canopy planters on the first floor, along with the artwork and relocated tree along Division.  Contractor Lorentz Bruun along with landscape contractor Landservices of Oregon has done a great job of dealing with the unique complexities of the site and landscape elements and realizing the beautiful structure design by Francis Dardis of Stack Architecture.

The relocated tree was moved in a couple of weeks ago, a 25′ Japanese Maple that previously sat on the site near the house that was moved.  Developer and owner Urban Development Partners (UD+P) had the foresight to have the tree moved and stored off-site by Big Trees Today, then brought back to provide instant green along the street.  To accommodate the move, the root ball measured 100″ diameter, as seen in the photograph below.

The tree sits adjacent to the new cor-ten metal sculpture by Ivan McLean, which acts as a vertical wetland to capture water from building roofs and express the movement prior to conveyance back to the larger flow-through planter.  The sculpture itself measures 10′x10′ and provides a thin wedge that is both substantial and airy.  Below is the sculpture arriving on-site.

And it being located in it’s spot adjacent to the building along Division, where it will act as an iconic marker for passing traffic. Plantings will be located on top, inside, and along the front edge and water will travel vertically throughout these zones prior to overflowing.

The eventual route for stormwater comes to the extensive flow-through planter, located along the rear property line, which provides stormwater management for the site per City of Portland standards, which is particularly crucial as the site is located in a Combined Sewer Overflow area, so this site will hold water on-site for longer, alleviating pressure on the system in peak flows, and ensuring better water quality for our regions streams and rivers.  This infrastructure on-site is augmented by permeable paving in all other site locations – shown in the irregular patterning of gray and brown square unit pavers.

The other piece coming together is the living wall that will wrap the exterior of the trash enclosure.  This innovative feature, one of many funded by Metro as part of their Green Innovation Grant program – including the vertical wetland, green canopies, wildlife art, and signage.  The initial structure was built, which will house recycling and garbage but will be transformed into a significant site amenity.

Due to the central location, the concept calls for a series of troughs that wrap around two sides of the structure – designed by TERRA.fluxus and fabricated by Ivan Mclean – which will provide for a tapestry of vegetation that will provide color, texture, and scent to this area.  The initial armature has been welded in place, and you can see the structure along with a close-up of the troughs – which will hold soil and plants, and be irrigated with linear drip tubing.

KPV Planters Installed

by Jason King

The design for the Kohler Pavilion Green Screen rehab at Oregon Health + Science University was recently completed, with new soil, trellis armatures, and plantings in and beginning to make their way towards the screen panels – with an aim of providing a lush green cover to the project exterior.  A total of 63 planters were rehabilitated spanning 3 levels and wrapping around two sides of the building.

A variety of plantings are distributed along rigid metal trellis stakes – to allow for a jump from the planter to the screen, which varies but is almost 24″ away from the actual planted area.  The stakes provided an easily installed, yet long-term solution, required little fabrication, and allowed for multiple lengths – with an easy hook into the existing screen.

As you can see from the concept drawing, the project came together very close to the goal – and was able to take a relative narrow planter and expand the plantings out 10′ to provide more coverage visible from the exterior.

At this point the Clematis armandii is the most vigorous, climbing to the screen and adding as much as 12′ of growth in a short period of time.  Fine tuning of the irrigation and diligent training of the remaining vines, including Carolina Jessamine, China Blue Vine, and Fiveleaf Akebia – will allow for these plantings to quickly fill in providing variety of texture and color, while remaining a lush evergreen screen throughout the year.  We will monitor and see what the exterior looks like periodically through the summer and fall – but feel comfortable that the vegetation will be full after a year.

OHSU Green Roofs

by Jason King

A pair of bookends to the main hospital building at Oregon Health+Science University (OHSU) – the HRC and C-Wing projects (see previous posts here and here) have now been installed and growing for a couple of months.  Working with Snyder Roofing of Oregon and Teufel Landscape, the first of these design-build projects to go in was the C-Wing, a narrow rectangle visible from above.  The pattern of pathway and linear bands of vegetation plays off the rhythm of the existing windows, and is evident in the initial established vegetation at grade, and from above. 

Soon after, the Hatfield Research Center (HRC) was installed, featuring a grid pattern of different vegetation types, adapted to the mostly shade condition between buildings.  The close up shot shows the blocks of planting, along with the abstract ‘stream’ of blue glass that meanders through the grid from drain outfall to drain.

This visual elements is vibrant when viewed from above, such as the adjacent patient rooms and corridors, such as this view from the 9th floor pedestrian walkway.
