In the early 1990s, Donald Judd sought the advice of engineers and architects to address the façade of 101 Spring Street, though at that time the restoration proved too costly for him to realize. In May 2013, Judd Foundation completed the restoration of 101 Spring Street. The restoration aimed to both restore and preserve the building’s original architecture, Judd’s design interventions and installation; and make the building accessible to the public for the first time. 101 Spring Street opened to the public in June 2013.

Led by Judd Foundation Curator and Co-President Flavin Judd, Board Member, Robert C. Beyer and the Judd Foundation Board of Directors, the project is recognized as an outstanding example of historic restoration and won the following prestigious awards:

Historic Restoration
Planning for the restoration began in the early 2000s. In 2010, construction began with the support of the National Trust for Historic Preservation. The project was designed to conform to the highest qualities of preservation, meeting the “The Secretary of the Interior’s Standards for Rehabilitation” guidelines for historic preservation issued by the National Park Service. 101 Spring Street is listed as a contributing building to the SoHo-Cast Iron Historic District.


The main element of the exterior restoration was the refurbishment of the original castiron façade, which provides both the enclosure and structure for the building. Since construction in 1870 the façade had deteriorated significantly, therefore the restoration project required the removal of 1,300 non-structural, cast-iron elements for treatment or recasting at a specialized foundry before being re-attached to the building. Structural columns were treated in place. The exterior was repainted to match the medium gray color of the building during the time that Judd owned it. The original cast-iron was cream colored, including fine sand particles, which was typical for 1870 as a means of emulating the appearance of stone. The existing wood window panels, which account for two-thirds of the façade area, were replaced with new wood frames detailed to match the originals. The poor condition of the existing windows precluded repair. It was essential to upgrade the glazing from single-pane to insulated and ultraviolet light protective units given the requirement to improve interior environmental conditions.


Primary Exterior Work
• Cast-iron restoration, including removal and refurbishment of all cast-iron spandrel panels
• Window restoration including removal and replacement of all windows and glazing
• In-kind replacement of fire escape
• Refurbishment of cornice
• New roof, skylights, and structural steel to support new roof equipment
• Insulation added to exterior walls
• Sidewalk vault structural repair and sidewalk vault lights (skylights) replacement
• New interior waterproof membrane and concrete liner wall below grade (cellar and sub-cellar levels)


The aim of the interior restoration was to return the building to the aesthetic condition of 1994, the year Judd died. The above grade levels, floors one through five were maintained as the artist’s home and studio, installed with Judd’s personal effects and collection. The below grade levels were modernized for use by Judd Foundation. The cellar level provides office space, following the layout of the existing pine partitions built by Judd, and in the sub-cellar, a conference room, public bathrooms, and mechanical rooms are housed. To the largest extent possible, existing materials and interior surfaces were preserved to retain the intrinsic qualities of the historic building.


Public Accessibility
Providing code-compliant public access to the building required the addition of contemporary life safety and fire suppression systems. The existing staircase above grade level is a critical part of the experience of the building and was maintained as close to the original as possible. Challenged by the code-issues of this non-enclosed stairway, the design and engineering team developed out-of-sight fire detection and management systems to meet public safety requirements, without compromising Judd’s design intentions.


Museum Quality Environmental Conditions
To protect the artworks, furnishings and the interior space itself, the Foundation undertook a conservation study to determine the appropriate environmental conditions for the interior spaces of the building. To meet these requirements, the project included the addition of new heating and cooling systems, where possible incorporating existing fixtures to minimize visual impact in the spaces. New windows and shading system were installed to protect the collection from ultraviolet light transmission and heat loss/gain.


Green Design
The project was not an appropriate candidate for LEED certification, as it was a restoration of a historic building with limited interior work, however, the design parameters of the building were set to reduce energy use. Energy efficiency was achieved through improvements to the exterior envelope, including added insulation to the roof and walls, new insulated window glass with tighter-fitting frames, and new high-efficiency natural gas boilers with modern temperature controls.
