The Hugh Gregg Coastal Conservation Center, constructed in 2005, is a modern education facility that provides valuable meeting space as well as exhibits on the upland habitats of the Great Bay Watershed.  Built in the old New England post and beam style barn, this facility has several sustainable design features, including a geothermal heating and cooling system and composting toilets.  The large and airy meeting space can hold up to 225 people and is ideal for presentations or can be reconfigured for training sessions with tables.  Adjacent to the Great Bay Discovery Center, the grounds are beautifully landscaped and feature several hiking tails.
