Museums to Municipalities

PTF has worked with large urban museums like the MFA-Boston and remote historic sites like Wood Island Life Saving Station. Some follow strict preservation guidelines, like the Marrett House, and others are innovators in adaptive re-use, like the Mill at Freedom Falls. Some of our most interesting projects are the ones that defy categorization, like the Hampton Town Clock Tower. The following is a list of projects with a secular, public mission. Or you can read more in-depth posts on our blog.

*Indicates properties listed on the National Register of Historic Places


Structural restorations to the former US Coast Guard lifesaving station on Wood Island off the coast of Kittery, Maine. PTF, along with General Contractor, Chesterfield Associates, and abatement teams from Envirovantage, completed the first Phase of the restoration project: hazardous waste removal, internal and external structural repairs, new asphalt roof, and weathertight skin. Restorations will be completed in future phases.

LEWIS CONSERVATION CENTER, Kensington, NH     2014-2015

Design and creation of timber frames based on traditional historic timber framing common in New England in the early 19th century.  The frames were built with traditional methods using hand tools to ensure authenticity, beauty, and strength. Of the six frames, one is an existing historic timber frame from the 18th century that we carefully repaired with in kind materials; while another frame is modeled after the 1722 East Derry Meetinghouse in East Derry, New Hampshire.

*MILL AT FREEDOM FALLS, Freedom, ME    2012

Structural rehabilitation of grist mill (c. 1834), and resurrection of attached ell.  The crew faced a number of obstacles: one corner of the building had dropped more than 10 inches out of level, and a stream that once powered the turbine still runs between the granite walls of the foundation.  Stabilization of the structure required building staging around and on top of the works of the turbine, 16-20 feet above the rushing water.   After stabilizing the building and the cutting the repairs, the crew was tasked with installing 12″ x 16″ hemlock timbers of lengths up to 22 feet over the rushing waters.  Read our blog posts about the process.

I-FARM, Boxford, Massachusetts     2009 – Ongoing

I-Farm is a multi-building complex soon to become a working farm that teaches early farm technology and sustainable agricultural practices. Our work there began with the complete restoration of an historic barn that had been built with timbers reused from an earlier English barn.  Our recent projects include the restoration of a water tower and utility shed, building the timber-framed addition to the kitchen ell, and creation of black locust arbor and trellises. Currently, we are restoring the main residence.

*Moffatt-Ladd Museum, Portsmouth, New Hampshire    2008, ’12, ongoing

2012 – Scraping and restoration of exterior facade.  Please read about our paint prep process, here.

2008 – Extensive structural repairs of the “Counting House” including sills, floor girts and timber framed elements in the front eave wall.  Siding and Roofing removed and repaired in kind.  Extensive structural repairs to “Back Ell” including the replacement of porch posts to more closely match the original configuration of the ell.  Roof structure was repaired and new sheathing placed before installing a new white cedar shingle roof.  Copper gutters were also installed to direct rain water for use in the gardens.

After completion of the restoration of Moffat Ladd counting house, PTF repaired an historic arched window for the mansion.  The lites of the arch had been cut out of a single board, whose grain ran horizontally, meaning that some muntins were composed entirely of short grain.  Some muntins were two-part, with the inside, molded profile applied to the outside, glazing bar, a detail found in some Georgian windows.  Contact Arron Sturgis for more information.

1999 – 2004 – Extensive sill replacement on three story red pine timber frame structure.  This museum required extensive girt, post and stud repairs along three sides.  Continued structural repair of undercarriage.  Provided technical assistance in on-going Historic Structures Report.  Yearly maintenance, preservation planning and grant writing. This high style Georgian residence dates to 1762.

Sheafe Warehouse, Prescott Park, Portsmouth, NH    2011

The Sheafe Warehouse is a timber frame warehouse built in the early 18th century.  Its second story overhangs the Portsmouth’s harbor, an innovation that made it easy to unload cargo directly from the decks of Piscataqua gundalows.  In 2011, PTF reshingled the roof, with the help of our Maine Preservation interns.  Keith Trefethen is the ongoing job lead in PTF’s participation in the preservation of this and other buildings in Prescott Park.

*Sabbathday Lake Shaker Village, New Gloucester, Maine    2010-ongoing

PTF built new piers and a floor support system for the later portion of the Herb House, as well as installing new perimeter sills, floor joists and post feet in the earlier portion of the building.  When carpenters were repairing the floor beneath the stairs, they removed a portion of wall that had been hiding former storage space which still held an old seed tray, a rare artifact.  These discoveries are part of what makes preservation work rewarding.  We are fortunate to work on buildings built by carpenters renowned for their craftsmanship.  Contact Dan Boyle for information about this project.

*Museum of Fine Arts, Boston, Massachusetts    2009

Repair and reinstallation of the Brown Pearl Hall and the Manning Room Frame within the new wing of the museum.  Work included the careful restoration and repair of two timber frames removed from the museum four years prior.  The Brown Pearl Hall was created in collaboration with museum staff and historic mason as an authentic first period room to eventually be furnished to represent that time period.  The timber frame, historic fireplace and plaster walls and original wide pine flooring were repaired and set exactly as had been the original roof configuration.   The Manning room was transformed to a freestanding timber frame within which period furniture and other sculpture would be placed.  All work was documented extensively through photographs and careful measurement.  Contact Arron Sturgis for information about this project.

Fogg Museum, Harvard University, Cambridge, Massachusetts    2008-2009

Removal and transport of Carved Ceiling Beams from the Hôtel Desbarres, Dijon, c. 1540.  The carved oak beams are 30 ft long and 14″ by 14″.  The beams were documented, lowered on staging from 25 feet in the air and into specially made crates to protect and store the historic fabric.  These crates were then transported to long-term storage during museum renovation.  The crates were 30 feet long and some weighed as much as 4200 pounds.  Contact Arron Sturgis for information about this project.

From Gilman, Roger, Bulletin of the Fogg Art Museum, Vol. 4, No. 1 (Nov., 1934), pp. 10-15, “In the Fogg Museum the main architectural feature, after the central court, is the great ceiling in Warburg Hall.  Its dark beams of oak, moulded and richly carved, with their heavy framework of cross beams, make a worthy setting for the Museum’s twelfth century capitals.  It is known to have come from Dijon, out of an old building in the court of number 3 rue Jeannin, and it is apparently late Gothic in style…”


*Historic Harrisville: Mill Number One, Harrisville, New Hampshire    2006

Complete restoration of eight sided belfry and dome on stone mill building.  The belfry framing was removed to the ground to allow its safe and comprehensive repair.  The belfry bed timbers within the stone tower were replaced in kind and bolstered to support the weight of the belfry.  The metal roof on the dome was scraped and painted.  The exterior trim on the belfry was removed and repaired and stripped and re-painted and then re-applied to match the original trim configuration.  A new copper soldered seam roof was installed over new sheathing boards applied to the original hip roof beams.
