There’s a particular type of New England colonial house that I’ve always admired: Georgian, with a hipped roof and two entrances, almost as if two houses had been joined together at a right angle. The profile is square but you generally see just three corners–which is why I refer to these houses as “tricorner” houses. I think I’m the only person that uses this term. My two favorite examples of this type of house are the Jeremiah Moulton house in my hometown of York, Maine, and the Thomas Ayres Homestead in Greenland, New Hampshire, and I happened to be driving by both of these houses yesterday so I took some pictures. I would have had to infringe of the privacy of the Moulton House’s owners to show you the perfect illustrative angle, but the Ayres house represents a tricorner house perfectly even though it has two additional entrances on the side rather than one. My rule (and again, it’s just mine) about these houses is that the length of the side structure has to be roughly equal to the front, and it cannot appear to be just a mere addition, but an integral part of the entire house.
Like tricorner hats, tricorner houses are eighteenth-century creations: most of the ones I have seen date from the 1730s through the 1760s. They all have two stories, and seem to be more characteristic of rural environments rather than urban ones–or maybe they have just survived in less-developed areas. There are quite a few in central Massachusets: if you browse through the digitized photographs of colonial houses taken by Harriette Merrifield Forbes at the American Antiquarian society you will come across several, especially taverns. Case in point: the Jones Tavern in Acton, Massachusetts, which acquired its tricorner shape between 1732 and 1750. I think tricornered houses (at least by my own conception) have to evolve rather than be built as such: high style examples like the Willard House at Old Deerfield and the Salem Towne House at Old Sturbridge Village have the requisite two sides/entrances but are not quite right–the corners are too sharp!
My favorite “tricornered” houses: the Moulton House in York, Maine, the Ayres Homestead in Greenland, New Hampshire, and the Jones Tavern in Acton, Massachusetts. Please forward more examples!
