There’s a new green project under construction in New York’s West Chelsea Arts district that just so happens to be the first free-standing project for Neil M. Denari Architects.  Known as High Line 23, or HL23, the design is defined, at least in part, by the small ground floor footprint of 40′ x 99′.  As you can tell from the images, the building starts small and hovers 14 floors into the air over abandoned railroad tracks (note: those tracks will soon be a thriving green park area).  The $22 million, 39,200 sf condo tower will have a private garden at the building’s base and 11 condo homes — nine full floor residences and a duplex penthouse on the top floor.  Residences range in size from 1,850 – 3,600 sf and price from $2.7 – $10.5 million.

HL23 also will have a laundry list of green features: natural ventilation, abundant natural light, low VOC interior materials, water saving fixtures and appliances that reduce consumption by 30%, highly reflective roofing to reduce heat island effect, an efficient building envelope that reduces energy consumption by 15-25%, use of reused and recycled materials, and a construction waste plan that diverts at least 75% of waste from landfills.  HL23 was designed to achieve LEED Gold certification, so you can expect a ton of other green features, too.

Construction is expected to be complete late 2009.
