Imagine you want to build a house on a steep hill. Every time you try to set a wall, it starts sliding downhill. The ground is uneven, one side of the house ends up a whole meter higher than the other, and digging out a level building pad is very expensive and time-consuming. What to do? That was exactly the problem Seattle residents faced in the early 1900s, when the city began to grow and flat building lots became increasingly scarce.
Then ordinary carpenters and builders came up with a brilliantly simple solution: they began setting houses on short wooden “stilts” — short posts they called “Seattle piers.” This invention changed the whole city and allowed thousands of ordinary families — teachers, postal workers, tailors and bakers — to buy their own lovely homes on Seattle’s hills. The story of how a simple idea made the dream affordable for many began with a big problem and a few clever minds.
The hills problem and costly solutions
Seattle is built on many hills that slope steeply down to Puget Sound. In the late 19th century wealthy people could afford to hire engineers to level lots, build expensive stone foundations, or use complex retaining walls. One such foundation could cost as much as the rest of the house! For a family where the father worked at a sawmill and the mother took in boarders to earn extra money, that was simply impossible.
Traditional building methods required a level, solid foundation. On flat ground that’s easy — dig a trench, pour concrete or lay stone, and you’re done. But on a slope one side of the foundation must be much deeper than the other, which means a lot of digging, a lot of materials and a lot of money. Some families saved for their houses for decades and still couldn’t afford it.
Local builders looked at the problem and thought, “There must be an easier way!” They saw how Indigenous peoples built longhouses on posts, how fishing piers stood on pilings in the water, and how farm granaries were sometimes raised on supports to protect them from moisture. What if that idea were used for ordinary houses?
The invention of “Seattle piers”
The solution turned out to be surprisingly simple. Instead of digging a deep foundation, builders began installing short wooden posts — usually made of durable cedar that resists rot. These posts were set directly on the ground (sometimes on flat stones for stability) about a meter apart. The height of each post was adjusted so the tops of all the supports were at the same level — even if the ground beneath them was uneven.
Imagine a table with legs of different lengths so it sits level on an uneven floor — that’s roughly how these piers worked. On a sloping lot the posts on one side of the house might be only about 30 centimeters high, and on the other side one and a half meters. But from above you got a perfectly level platform on which to build the house.
The solution had many advantages. First, it was fast — an experienced crew could set all the piers for a house in a day or two instead of weeks of work for a traditional foundation. Second, it was cheap — cedar posts cost very little, especially in Seattle where sawmills operated around the clock. Third, the space beneath the house provided storage, and good ventilation from below protected the wooden floor from rot. In rainy Seattle that was very important!
Builders quickly standardized the system. They worked out the optimal spacing between piers, the best post dimensions, and methods for installation. Soon any carpenter in the city knew how to build a house on “Seattle piers,” and the knowledge passed from master to apprentice. The system was so reliable that many of these houses still stand today — more than a century later!
Catalog houses: when the dream arrived by mail
But the invention of the piers was only part of the story. Around the same time an astonishing innovation appeared in America — mail-order houses. Companies like Sears, Roebuck and Company and Montgomery Ward began selling complete houses by mail! You could open a thick catalog, pick a house you liked (they had charming names like “Ardmore” or “Columbia”), place the order, and a few weeks later a freight car would arrive at the nearest railroad station with numbered parts for your future house.
It was like a giant kit! The package included all the boards already cut to size, windows, doors, nails, paint, roofing shingles and even a detailed, illustrated instruction manual. Every piece was numbered, and the guide showed which board to nail where. A family could build such a house themselves in a few months working on weekends, or hire local carpenters who would assemble it in a few weeks.
For Seattle this was the perfect combination! “Seattle piers” solved the problem of hilly land, and catalog houses made construction simple and affordable. A Sears catalog house could be bought for $1,000–$2,500 (roughly equivalent to buying a good car today), and the company even offered financing. Many working families could, for the first time, afford to own rather than rent.
The style that became especially popular was called the “Craftsman” or “American Craftsman bungalow.” These houses were modest (usually one story or with a finished attic), but very cozy and attractive. They had wide porches for sitting on summer evenings, open interior layouts, built-in cabinets and buffets, and beautiful woodwork. They looked sturdy and substantial, even though they were built quickly and inexpensively.
Neighborhoods built by residents themselves
The history of the Ballard neighborhood in Seattle shows how this system worked in real life. In the early 1900s Ballard was a separate town populated mainly by Scandinavian immigrants — Norwegians, Swedes and Danes. Many worked in sawmills, in fishing, or building boats. These were people who knew how to work with their hands and weren’t afraid of hard work.
When land in Ballard became available for purchase, families snapped up plots on the hills. Neighbors helped one another: one knew how to set the piers, another was good on roofs, a third was an excellent joiner. On weekends an entire crew of neighbors would gather, and within a few months a new house would rise on an empty lot. Then they would help the next family, and so on.
Women played an important role in this process, though their contributions are often forgotten. Many widows or wives whose husbands worked seasonal jobs in Alaska or at sea managed their homebuilding projects themselves. They chose the plans, ordered materials, hired workers and supervised the work. Some women specifically built houses with extra rooms to rent out — a common way for women to earn income at the time.
One such story survives in the archives of the Ballard Historical Society. A woman named Ingrid Larsen ordered a Montgomery Ward catalog house on a hill lot in 1912. Her husband worked on a fishing vessel and was gone for months at a time. Ingrid hired a crew of four carpenters who built the house on “Seattle piers” in six weeks. The house had four bedrooms — the family used one and rented out the other three to workers from a nearby sawmill. Income from the boarders allowed Ingrid to pay off the loan on the house in just five years!
Gradually entire neighborhoods filled with these cozy bungalows on piers. The streets of Ballard, Fremont, Wallingford and Green Lake became lined with rows of similar-but-not-identical houses. Each family added something of its own: someone painted their house an unusual color, someone built a distinctive porch, someone planted a special garden. The result was neighborhoods where houses were similar enough to create harmony, yet varied enough that each had its own character.
The legacy of a simple solution
Today, more than a century later, these neighborhoods are among the most desirable places to live in Seattle. The very “workers’ houses” built as affordable homes are now expensive — not because they are luxurious, but because they created a special atmosphere. Tree-lined streets, human-scale houses, porches where neighbors can chat, gardens and yards — all of this makes these neighborhoods lively and welcoming.
Many of the original “Seattle piers” still support these houses. Cedar proved so durable that century-old posts continue to perform. Of course, some houses have been renovated and had their piers replaced with modern foundations, but surprisingly many have retained the original construction. Engineers say that with proper maintenance these piers can last another hundred years.
More importantly, the idea lives on. Contemporary architects designing affordable housing study these old neighborhoods. They ask: “How did builders back then create good-looking, high-quality homes that ordinary people could buy? What lessons can we learn?” It turns out that simplicity, standardization, and use of local materials are principles that always work.
The story of the “Seattle piers” teaches an important lesson: sometimes the best solution is not the most complicated or expensive, but the smartest and simplest. Those builders didn’t invent anything wildly new — they simply looked at old ideas with fresh eyes and adapted them to their problem. They didn’t wait for someone else to solve the problem of costly housing — they solved it themselves, with their hands and their heads.
And the most beautiful thing: they created not just houses, but communities. The neighborhoods that grew thanks to this system became places where people knew their neighbors, helped one another, and created traditions. Because when you build your house yourself or with the help of neighbors, when you choose every detail and invest your labor — the house truly becomes yours. And a street full of such houses becomes a truly vibrant place.
So simple wooden posts helped thousands of families achieve the dream of homeownership and created neighborhoods people still love today. Sometimes the biggest changes begin with the simplest ideas — you just need to look at the problem from the right angle and not be afraid to try something new.
