This project involved the construction of a 10,000 square foot addition to house the owner's original art collection.   Special features include reinforced walls to support the artwork, as well as marble and a one-coat finish throughout.   Doors are as unobtrusive as possible -flush with the walls with no doorknobs.   The pristine look of the interior, 27 foot ceilings and a museum lighting system provide maximum exposure for the one-of-a-kind collection, while beautifully integrating with the rest of the house.
