The long rear slope of a saltbox house looks like one clean architectural decision. It often was not. At the Thomas Lee House, earlier rafters were cut and extended around 1765 to cover a new lean-to. At Hyland House, a displaced roof support and an added flue reveal that the rear rooms came later. Buttolph-Williams once had the familiar profile, then restorers removed its rear ell in 1947. At the Ogden House, the visible roof does not settle the sequence at all.

A roofline identifies the shape a house has now. To establish how it acquired that shape, the useful evidence is inside the frame—and in the restoration file.

Four houses, four different saltbox records

HouseWhat the roof seems to sayWhat the evidence actually establishes
Buttolph-Williams, WethersfieldA late-17th-century two-story colonial house rather than a clear saltboxA later rear ell had completed a saltbox profile, but the 1947 restoration removed it
Hyland House, GuilfordA continuous rear lean-to under the long slopeThe lean-to came after the 1713 core; its fireplace flue forced a change in the original rear chimney bay
Thomas Lee House, East LymeA settled saltbox compositionThe late-1660s core grew through a circa-1709 west addition and a circa-1765 lean-to that required cut and extended rafters
David Ogden House, FairfieldA house built as a saltbox around 1750Public interpretation uses 1750, while HABS records initial construction in 1710–1720 and later work around 1750; the lean-to sequence remains unproved

Buttolph-Williams: restoration removed the saltbox phase

The Buttolph-Williams House is commonly dated to 1692 through ownership and family records, not a scientific timber date. Its early core follows a two-room, central-chimney plan. Later owners altered it inside and out and added a one-story rear ell, producing the classic extended profile associated with a New England saltbox.

That is not the shape visitors read today. When the Antiquarian and Landmarks Society restored the house in 1947, the later ell was removed as part of a campaign to recover a proposed seventeenth-century appearance. Later siding and finishes also disappeared. Riven oak clapboards and diamond-paned casement windows were installed during the restoration.

Buttolph-Williams therefore exposes a preservation choice: the restoration privileged an earlier two-room core over the later form that had made the building look more like a saltbox. The present exterior cannot demonstrate the full building history because one of its major phases was deliberately subtracted.

Hyland: the chimney bay proves the lean-to came later

Hyland House supplies stronger physical dating. A 2015 dendrochronology study dated its earliest structure to 1713, correcting Norman Isham’s 1916 estimate of about 1720. The first house contained two ground-floor rooms with chambers above; the rear expansion followed later.

The proof is not simply the unequal roof. In the attic, the original structure remains largely legible except at the rear chimney bay, where a roof support was lowered so a flue from the lean-to fireplace could pass through. That intrusion establishes sequence: chimney system and lean-to were fitted to an earlier frame.

The visible colonial details also require labels. During the 1916–1917 restoration, Isham replaced nineteenth-century facade windows with diamond-paned sliding sash, rebuilt the chimney above the roofline and inserted a window from the Henry Whitfield House into the rear wall. Some interior paneling and sheathing came from elsewhere or was installed without evidence for that exact room. Hyland is most useful when the restoration layer is read alongside the original frame.

Thomas Lee: the rafters record the conversion

The Thomas Lee House has the clearest construction sequence in this group. Its earliest portion dates to the late 1660s and contained lower and upper chambers with attic space. A west section followed around 1709, built as a structurally separate addition on its own corner posts.

The saltbox transformation came around 1765, when a lean-to kitchen and side rooms were added. The existing roof could not simply continue over the new rooms: its rafters were cut and extended, lowering the rear pitch into the present saltbox shape. Here the asymmetric roof is not a stylistic label applied from outside. It is the visible result of a documented alteration to an older frame.

Norman Isham restored the house in 1914–1915 after its domestic use had ended. That intervention still mediates what visitors see, but the cut-and-extended rafters preserve the more important evidence: the rear slope records adaptation rather than one original build date.

Ogden: the date and the lean-to remain open questions

Fairfield’s interpretation associates the David Ogden House with the couple’s 1750 marriage and move into the property. HABS records a different sequence: initial construction in 1710–1720 and subsequent work around 1750. Neither date is supported here by dendrochronology, so “built in 1750” is a public interpretation rather than a settled physical date.

The selected records call Ogden a saltbox and explain that lean-tos could be added after an initial house was built, but they do not establish whether this particular rear section was integral to the early frame or added in the 1750 phase. The garret exposes wood strips and shell-bearing plaster that help explain construction, not the missing chronology of the roof.

The current appearance also reflects a 1931 restoration by Isham and Henry Stoddard that removed Federal-period additions to recover a perceived mid-eighteenth-century form. Ogden is a useful place to study a restored saltbox, but not to claim that every visible roof plane belongs to one documented year.

Read the joints before the outline

From the road, a long rear slope proves only that the current building has a saltbox profile. Inside, four kinds of evidence can establish more:

  • Cut, spliced or extended rafters show that an older roof was altered, as at Thomas Lee.
  • Flues interrupting an earlier chimney bay can place a lean-to fireplace after the main frame, as at Hyland.
  • Independent posts, sills and joints separate additions from the first structural unit.
  • Restoration records identify removed ells and reproduced windows that the exterior no longer explains.

That evidence leads to a less tidy but more useful reading. A saltbox may be an original plan, a later household expansion, a roof rebuilt across several phases or a museum silhouette selected by restorers. The outline names the form; the frame tells its history.
