The 5 Green Star MPI (Ministry of Primary Industries) Multipurpose Building in Upper Hutt covers a number of functions from café to seminar rooms.

Although designed with a conservative budget, forward thinking generated many sustainable elements, including a 125 sqm swale. The swale, planted with native grasses and reed species, eliminates the need for storm water drainage and allows water to penetrate into the ground with no need for additional irrigation. The feature, which leads into a soak pit to prevent waterlogging, is built to protect the site from a 1-in-50-year storm.
