The United States has always been one to do new things in a big way. In this case the concepts are not exactly new, but they are big! 

The USDA announced early last week the winners of $3 million in funding grants in support of greener, carbon friendly wood based high rise construction technology. Modern engineered Mass Timber products have made the continued development of high rise timber projects around the world possible.

Between the years 1880 -1940 there were over 300 Mass timber projects built in the "new world" centres above 6 stories, with the tallest being 9 stories. These projects have not only demonstrated the viability and longevity of these structures, but many of them have served to show the amazing beauty of these authentic marvels. Shortly after World War II, steel and concrete took over the leading rolls in construction development. Timber and many other natural materials were left in the dust believed to be old and inferior materials.

Although Cross Laminated Timber was developed in the mid 90's, the modern timber renaissance did not start until around 2005 when a series of forward thinking Architects started to develop taller timber structures. Engineered  Mass Timber products gave designers the reliability to make these redevelopments. Building codes around the world have had to be re-examined to allow the implementation of such tall timber projects, a copious body of testing has almost universally shown Mass Timber to exhibit extraordinary fire protection properties along with a slew of unique structural characteristics. These properties are only part of the side show though as one of the primary motivations for choosing wood based products in our modern era is to use renewable materials while reducing our carbon footprint. Mass timber inherently excels in both of these attributes. 

One of the two grant winning projects consists of a 12 story, mixed use building in downtown Portland, backed by the Beneficial State Bancorp. The project is supported by a motivated group of key Oregon movers who are seeking to revive Oregon's turn of the century Timber Legacy.  Lever architecture is providing the vision behind the interesting building pictures on the top left. 

ARuP and SHOP Architects have teamed up to turn new leaf over in the big apple. New York is set to see a 10 story residential development at 475 West 18th. The project focuses on a drastic reduction to building energy load as well as the goal of reaching LEED platinum. 

The next few years will surely be interesting as we see Mass Timber projects each take their own approach to a perfect system. How do you measure the success of these building systems? 
Occupation use? Carbon footprint? Aesthetic  review? Time to complete? Life-Cycle Costs? Or raw construction costs? The answer is linked to all of the above. With the right teams being assembled we are seeing the dawn of the Mass Timber Renaissance, were these projects will outrun concrete and steel alternatives in all categories. For the time being we are only limited by our dreams.

Dalston Lane is a new project in the Hackney region of London. CLT was selected as a primary building component due to its weight reduction over concrete. Poor soil conditions combined with existing underground development made CLT a perfect fit for modern, green, in-fill architecture. The building is 10 stories tall with 9 of them out of CLT.  The project will use over 3,500m^3 of European timber, locking up 2,400 tonnes of carbon while providing housing for 121 units. 

The project team consists of a set of local UK superstars in modern construction including Ramboll Engineering, Waugh Thistleton Architecture, and Regal Homes. 

The 33m tall timber complex is set to be completed by the end of 2015. How many more timber towers will we see before the end of the year?

MGA of Vancouver, BC has teamed up withDVVD from Paris and REI Engineering France to reimagine the Parisian skylines in a unique and sustainable manner. The proposed set of developments features a 35 story timber based skyscraper. 

The project features an innovative mix of a student hotel, market housing, and social housing.  The project is part of an on going redevelopment contest and system for paris where over 900 sites have been identified for innovative redevelopments. This project seeks to inspire future generations with green design and a context of sustainable development. More can be found below:

The Nanyang University of Technology in Singapore has developed plans for a massive wood based expansion to its facilities. Wood was chosen for renewable properties, and thermal qualities. The facility is set to include a massive sports hall with 70 m glulam spans. Combined with these recreation facilities are six 13 story on campus residence buildings. These residences will house 1,850 students and likely be made from CLT.
