1.0 BACKGROUND

The purpose of this project is to restore the historic wood components of the Exedra Room in the Edison family home, Glenmont, located in West Orange, New Jersey. This unique, character defining feature is a passageway that connects the historic Dining Room and the historic Drawing Room on the first floor. It is a significant architectural component of this

1880 Queene-Anne style mansion, designed to display plants and statuary. Because the stained glass ceiling in this room is illuminated with a series of lightbulbs, the skylight above the room also represents the unique relationship that Thomas Edison’s influence had on the decorative objects that were displayed inside of his family residence.

Thomas Edison National Historical Park is a National Park Service site located in West

Orange, New Jersey. The park consists of two separate sites, approximately one mile apart.

Thomas Edison’s home, Glenmont, is located in a private residential community known as

Llewellyn Park. Built in 1880, Glenmont is a 29 room Queen-Anne style mansion which remains intact, complete with interior furnishings and finishes that reflect the rich historic decorative period during the years when Thomas Edison and his family resided in the home.

The term “Exedra”, which describes this room, originates from a Shakespearean reference and was so named by Thomas Edison’s wife, Mina Edison. Ensuring that this architectural component is properly preserved guarantees that this part of the Edison history shall be shared with park visitors for generations to come.

The majority of the work shall be performed on-site, in-situ, in the Exedra, a historic room/passageway located on the first floor of Thomas Edison’s Victorian mansion, Glenmont. The small, period room, which is pentagonal in shape, contains several historic windows, one pair of historic exterior doors, two pairs of original interior glass front French doors, two additional original leaded glass interior windows, original lighting equipment and associated wiring, as well as historic woodwork and finishes. The mosaic, marble tile on the floor dates back to 1909.

In all instances, the selected vendor shall be responsible for protecting-in-place adjacent artifacts, built-in features such as the adjacent stained glass windows, all other historic windows and doors, historic steps and patios, historic surfaces such as walls and floors, modern carpeting, etc. both in the Exedra, along the path of travel used for installation and de-installation of any equipment or supplies or artifacts, and also the skylight, as well as the areas directly above the skylight, namely the exterior roof and wall areas where additional work may take place, as required. Protect in place measures may also be required in exterior areas adjacent to the Exedra, depending upon the selected vendor’s approach for completing this work. This is required in order to prevent damage to the artifacts, historic surfaces and architectural features, built-in features, gutters, adjacent exterior paint finishes, original windows and stained glass windows and skylights, modern carpeting, original electrical lighting and heating components, etc. Please note that in accordance with the Department of the Interior Preservation Standards, all historic architectural and building system features shall be retained, undamaged and whenever possible, remaining in their original location, such as the historic woodwork that frames the windows and the skylight, the original doors, the stained glass, and any original electrical lighting features or equipment as these may be reused to complete this project. The selected vendor shall also be required to adhere to park safety and security policies which shall be further detailed in this document.

Documentation work for this project, which can be performed off-site, shall consist of producing a treatment proposal outlining the contractor’s approach and methodology for restoring these wood components in this historic room. This proposal shall include a detailed description of the types of repairs that will be undertaken, their specific locations, and the materials that will be used for the project. This document requires NPS review and approval prior to the commencement of any related project work. Documentation work for this project will also include producing a final treatment report, outlining the work performed for the project, which includes before and after photos of the work.

1.1 HISTORIC BACKGROUND

The Exedra, a patio room which connects the two wings of the first floor, was added to the house’s original design by Thomas Edison’s second wife, Mina Edison. It serves as an area to display plants and statuary and also as an exit to the back patio. This Exedra, also referred to historically as the Fern Room, measures approximately 9 feet by 12 feet, and is situated at the southwest corner of the home. This passageway was designed by architect Wilbur Knowles of New York City, circa 1909-1910. As per a bill dated January 31, 1910, the work included mason work, carpenter work, heating ante-room, copper roofing, electrical work, mosaic work, skylight work, painting work, and leaded glass for a total cost of $6,048.09. The room is pentagonal in shape with straight north, east, and west walls. It has a curved southwest wall and a diagonal southeast wall. Most of the southwest wall and ceiling were glazed. As part of the design, two new doorways with plate glass French doors were fashioned out of windows, doorways which now connected the Dining Room and Drawing Room to the space. A third doorway on the southwest wall of the Exedra provides exterior access. The original marble tiles on the floor were likely chosen due to their suitability for displaying potted plants.

A historic 1914 photograph of the room shows that it is filled with potted plants, hanging plants, and palms. A 1916 photograph of the breezeway indicates that statuary on pedestals were also displayed by the Edisons in the Exedra. Original decorative woodwork in the passageway includes board and batten paneling, high baseboards, a shallow window seat, and a pine ceiling cornice. Long, narrow window sashes from a series of curved windows on the southwest wall. Two additional interior leaded glass windows on the east wall provide ventilation for the Telephone Room and the Lavatory Room located in a corridor below.

The 4 feet by 6 feet (approximate measurements) stained glass panel used as a skylight is identified as a “leaded glass dome light in wrought iron frame” in the 1921 and 1924 appraisals for the mansion. Most of the ceiling area for this small space is comprised of the stained glass skylight with only an additional small area at the south end of the room which is paneled in wood. The stained glass panel is supported on its interior side with four iron bars which form a grid over the stained glass panel. Historically, the panel was backlit with electric lighting provided by Thomas Edison. This electrical lighting equipment and wiring still remain in the area of the ceiling above the skylight identified as the “skylight cupola”.

The lighting system, which used a series of lightbulbs to backlight the stained glass, was installed in circa 1909-1910 by electrician George R. Boyce.

Existing Conditions:

The Historic Structure Report: Part II for Glenmont (2017), outlines the current condition of various architectural elements in the mansion. It indicates that, overall, there is an issue with the extensive wood trim elements on the mansion which are indicative of its Victorian style.

They have been exposed to the weather during periods of time when the home was not painted regularly, and have exceeded their cyclical lifetime. The report states that, “deteriorated or missing wood trim, moldings, and siding in multiple locations admit water and contribute to the degradation of Glenmont’s character defining features.”

An example of one of those character defining features is the Exedra, a small patio room which connects the two wings of the first floor, which was added to the house’s original design by Mina Edison in 1909-10. The room’s dome-like shape adds a bit of whimsy to the mansion’s complex first floor design layout. The Exedra serves as an area to display plants and statuary and also as an exit to the Den’s back patio.

Past issues with malfunctioning gutters and poorly constructed roof lines permitted water to pool in this area, causing serious damage to the stained glass ceiling and its frame, as well as to other interior room components, over the course of many decades. The water penetration issues were corrected during a 2017 roofing project at Glenmont. However, due to previous moisture issues, the wood elements in this room are fragile and in need of repair. This wood is visibly rotted with peeling and blistering paint. No known previous color analysis has been completed for the interior wood walls and trim in order to determine its original painted finish. The, likely original, painted and glazed areas of the room are flaking. The stained glass ceiling and its associated iron support bars were conserved in 2023. It is important to note that this stained glass ceiling will remain in-place and intact during this current project to restore the associated wood components of the Exedra.

2.0 SCOPE

The scope includes the restoration of the wood components in the Exedra Room in order to ensure that it is structurally stable and secures the envelope of the building. Please note that approximately forty percent of these wood components are associated with an exterior wall.

Project work also includes addressing any water penetration or glazing issues associated with the seven exterior windows. These windows are irregularly shaped (approx. 68 inches in length by 14 inches in width) and are part of the structure of the exterior wall in the Exedra.

This project also involves addressing repairs to the wood components in the ceiling of the

Exedra and issues associated with the exterior doors and the two sets of interior doors. Paint finishes will also be addressed on the perimeter of the two interior stained glass windows.

The project will involve selecting the most minimally invasive method as is possible, replacing in-kind only the wood components that are damaged beyond repair. The project will also involve conducting historic paint analysis to determine what the original painted finish for the interior areas/exterior areas of the Exedra were, in order to recreate them.

Applying these finishes to the Exedra is part of the scope of this project. This interior finish will be applied to all of the wood components inside of the Exedra as well as to any interior door frames or window frames or baseboards as well as to the wood components in the ceiling, including the frame around the perimeter of its stained glass element. All of this work shall be completed in order to return the interior of this space to its historic appearance.

The project will also involve protecting in place any adjacent historic and non-historic features or on-site areas in order to prevent damage to them during the course of the project mailto:beth_miller@nps.gov work. It will also involve temporarily securing the envelope of the building and any associated electrical systems or historic elements in this area, such as its stained glass, while the restoration work is taking place. This involves using industry-standard methods that are the least invasive to the historic structure. All design components of the project must be pre-approved by the NPS before the project can proceed. More specific tasks and requirements for this scope of work are outlined in section 4.0 of this document.
