How to read a Lancaster County farmhouse

In November, after the leaves are down and before the first real snow, the farmhouses between Ephrata and Strasburg become legible in a way they are not in June. The trees stop hiding the wings. The low sun rakes across the stone and shows every seam in it. You can see, from the road, where a house stopped being one thing and started being another.

Most people drive past a dozen of these without slowing down and register them as a single category. Old farmhouse. White trim, side porch, barn holding the horizon behind it. They are not one category at all, and the differences are readable from the driver's seat once somebody tells you what to look for. Nobody ever tells you. That is the only reason it feels like a specialist's knowledge.

What follows is a way of reading, not a field guide. Building here was practical and regional and slow to change, so the same forms repeat for well over a century. That is good news for a reader, because it means the exceptions carry the information.

Start with the shape of the main block

The oldest farmhouses standing today tend to be simple rectangles, taller than they are deep, long side to the road or the farm lane. The depth was set by the length of floor joists a man could source and lift and by what a hand framed roof could reasonably span. So a farmhouse got bigger by getting longer, never by getting fatter. That single constraint explains most of what you are looking at.

Then look at the front door. Dead center, with an equal count of windows on either side, means symmetry was the governing idea, a habit that arrived with Georgian and Federal fashion and stayed for generations because it looked correct and correctness mattered. A door pushed off to one side, two windows on one flank and one on the other, usually means an older plan behind it: a large room with a hearth, a smaller room beside it, and a stair wedged in between where nobody would put a stair today.

Then read the roof

Pitch is the closest thing to a date stamp on the outside of a house. Steep belongs to the era of wood shingles, which only work if water leaves fast. Gentler slopes arrive with manufactured roofing and cheaper transport. A very steep roof also produces that tall attic, finished at some point by someone, with less headroom at the eaves than any architect would allow now and better light than most rooms built this decade.

Count the chimneys and notice where they land. Chimneys at the gable ends usually mean heat served rooms at each end of the plan. A single central chimney suggests a different logic and often an earlier or more modest house. Newer brick above the roofline means the stack was rebuilt, which is ordinary, and worth knowing before you plan a fire in December.

The additions are the autobiography

Almost no working farmhouse in this county reached its present size in one campaign. A family built what it could pay for. Then somebody added a kitchen wing, because cooking on the original hearth in August was intolerable and everyone knew it. Then a summer kitchen or a wash house. Then a porch got enclosed. Then, sometime around 1978, a family room went on the back with a sliding door and a slab.

You can see the seams if you look for them. A change in the masonry coursing. A shift in window proportion. A roofline meeting the main block at a height nobody would have chosen. A wing whose floor sits one step down from the room it opens into, so that for the rest of the house's life every person entering will hesitate for a quarter second at that threshold.

None of that is a flaw. A house added to five times is a house that five generations found worth keeping. The step down is the evidence.

An addition that matches the original perfectly is usually the newest thing on the property.

Windows tell you about money and about time

Older sash has more panes and thinner muntins, because glass came in small sheets and wood was worked by hand. As glassmaking improved the panes grew and the grid simplified, twelve over twelve giving way to six over six and then to two over two. Wavy glass in an upper sash, the kind that makes the barn ripple slightly when you move your head, is one of the very few things in an old house that cannot be convincingly bought.

Look also at how deep the window sits in the wall. In a stone house the opening is a tunnel, with a heavy lintel above and a sloped sill below. In a later frame or brick house it sits near the surface. That depth is not styling. It is the wall doing its work, and it is why the light in these rooms falls the way it does, in a soft band along the floor rather than a flat wash.

Porches were added, and that is the point

A great many of these houses were built without the porches we now consider essential to their character. Porches spread in the nineteenth century and they were put where they earned their keep: shading a kitchen door, sheltering the path in from the barn, catching the evening side of the house rather than the road side. A porch running the full front and stopping at the corners was meant as an outdoor room. A narrow one tucked along a flank was a working threshold, a place to leave boots and set down a bucket and stand for a second before going in.

Materials, and what happened to be nearby

Builders used what the ground gave them and what the local kilns could fire, which is why you find fieldstone in one township and brick a few miles down the road. It is also why the mortar in an original wall is soft and pale rather than hard and grey. Old lime mortar is supposed to be softer than the stone, so the wall can move and weep without cracking the stone itself. When you see spalled, crumbling faces on old stonework, hard modern pointing is often what did it. Somebody was trying to help.

How to use all of this on a Saturday

Stand at the far corner of the property before you go inside. From there you get the whole composition at once: the main block, the wings, the roof planes, the way the house sits into or against the slope. Then walk the perimeter looking at only two things, seams and water. Where does the roof send water, where does the grade take it, and what has that answer been quietly doing for a hundred and eighty years.

Then go in and enjoy the kitchen. Stand in the deep window on the west side late in the day, where the sill is worn in the middle from people leaning on it, and understand that you are not the first person to stop there.
