Situated on a seam between South Boston and an expansive field of industry and infrastructure, the Macallen Building and landscape rise together as an icon of sustainable development in this rapidly evolving area. The LEED® Gold certified building and landscape were conceived in response to concerns about air and noise pollution, heat island effect and a lack of local greenspace. The development addressed the existing impervious asphalt site through the establishment of two layers of green roof as well as a large entry court of pervious pavers allowing stormwater infiltration.
The recreational terrace was raised four feet at the western end to provide depth for a lap pool, while elsewhere the growing media is mounded to create a language of hillocks with staggered high points.
Our judges responded to the aesthetics of the project and were impressed with the way the design used differing approaches to green-roof technology to create different environments at different tiers of the building. Another thing that helped this project to stand out to judges was the close relationship this project has developed with various landscape education programs – even becoming a classroom extension of the Harvard Graduate School of Design. But even outside of this formal educational component, both local students and anyone else passing through the neighborhood will be able to look up and see the progress of the highly visible sloping roof – providing a frequent reminder of this exceptional green roof project.
