1. Athenahealth’s ‘master plan’ drawing showing mockup of an office annex on the south side of the existing garage

2. Athenahealth’s presentation of mockup of garage annex, at same height as garage

3. Athenahealth proposes to allow the height of this annex to be up to 20’ above the garage (in a single story), with a possible 15’ additional height if the structure “promote sustainable practices”. Athenahealth also proposes that this structure’s setback from North Beacon Street may be as little as 25’.
