The community also has a 10-unit \u201cuber affordable\u201d YWCA building with a shared-kitchen.\u00a0\u00a0<\/p>\n \u201cThe group of residents are just wonderful, wonderful people,\u201d owner David Hall told HempBuildMag. \u201cIt ranges from parents of younger kids to retired couples with grandchildren in the area. And if you live here and you renew in one- or two-year increments, your rent won’t increase.\u201d<\/p>\n Subscribe for HempBuild Magazine\u2019s free newsletter<\/strong><\/a><\/p>\n Each tea house has a two-bedroom unit on the first floor and a one-bedroom unit with a large outdoor patio on the second floor. Each also has a storage loft with a pull down staircase \u201cwhich can serve as a crash pad for a son or daughter or grandchildren,\u201d Hall said. The units are a walkable half mile from the city center and the T-line station to downtown Boston.\u00a0<\/p>\n Hillside already has 12 fully occupied units <\/span><\/a>built with tip-up slabs, but those were made with concrete and foam insulation.\u00a0<\/p>\n The developers wanted a greener solution and after consulting with Northampton, MA-based HempStone LLC<\/span><\/a>, came up with hemp-lime.\u00a0<\/p>\n A sample 9,000-lb. hemp lime wall panel with six window openings rests at the construction site of the Hillside Center for Sustainable Living.

That means walls can be pushed upright with a forklift insead of a construction crane.\u00a0<\/p>\n The panels are designed around a coated steel structural frame which is sprayed with hemp-lime to create a 16-inch thick wall system. <\/p>\n The thick walls give residents a \u201csense of shelter,\u201d Hall says. \u201cThere\u2019s a real serenity in it that is powerful,\u201d he added. <\/p>\n To create the panels, Hillside has purchased a Ereasy spray machine and last fall sprayed some R & D panels with Americhanvre hempcrete spraymaster Cameron McIntosh and Damien Baumer the France-based inventor of the Ereasy.\u00a0<\/p>\n More recently the team created a full wall panel with six windows, getting ready to build a total of 48 panels to be assembled at the end of the summer, Hall said. Each 2-unit building will require eight wall panels.<\/p>\n <\/p>\n US Hemp Building Assn. <\/p>\n <\/p>\n HEMPALTA <\/p>\n <\/p>\n Sativa Building Systems <\/p>\n <\/p>\n Prairie PROducers <\/p>\n \u00a0\u201cIn the development world, it’s as much work if you do 20 or 40 units in a sense.\u201d\u00a0 Getting the engineering and prototypes right allows the assembly of the walls to save time. The company is also experimenting with plastering the outer walls right away to save even more time.<\/p>\n Saving curing time by lifting panels within a week of spraying and plastering right away are experiments that are possible because the Ereasy machine and binder uses less water, but still the Hillside project is breaking new ground by slashing curing time to much quicker than traditionally scheduled.<\/p>\n \u201cDavid is a bold, bold mover,\u201d McIntosh told HempBuildMag. \u201cBut to the risk-takers go the rewards.\u201d<\/p>\n Permitting and zoning moved through the building departments relatively smoothly, which Hall credits to the longtime multi-generational reputation of the company and their experience developing other multi-unit housing and renovating two formerly industrial mill properties in the Boston suburb.\u00a0<\/p>\n The units will still have some concrete, in the form of a fireproof concrete plank deck between the upstairs and downstairs units, Hall said. But the foundations have been built with repurposed crushed glass from a newly opened factory in Vermont.\u00a0<\/p>\n \u201cIt’s like figuring out how much to sin and not sin and the world of sustainability to get somewhere,\u201d Hall said. \u201cI believe that you’ve gotta do it in incremental steps.\u201d<\/p>\n <\/p>\n Haven Earth <\/p>\n <\/p>\n Hemp and Block LLC <\/p>\n <\/p>\n US Heritage Group <\/p>\n <\/p>\n Hemp Eco Systems<\/p>\n The company wants to prove that this style of low rise multi-family construction system is adaptable to any New England site. \u201cThe goal would be to replicate the very same low rise multi-family design elsewhere,\u201d the company website says.\u00a0<\/p>\n Using hempcrete as one part of a sustainable built environment is \u201cone of the things that we’ve all dreamed about,\u201d McIntosh said. \u201cHillside has\u00a0put it together with a number of other really awesome sustainable building techniques where hempcrete is great, but you could argue it’s not even the star of the show. \u2026It’s the logical progression to say hempcrete should be together with geothermal and solar and high-efficiency homes and rainwater catchment and native plantings. It\u2019s that whole package,\u201d he said.\u00a0<\/p>\n \u201cIt’s humbling that Americhanvre got the opportunity to help them with it,\u201d he added.\u00a0<\/p>\n A sample panel with a scratch coat of plaster at the Hillside Center for Sustainable Living.
