Ordinary Homes of the United States

Time period: 1890s-1920s, 1960s-1980s, 2020s to present day Location: Suburbs nationwide The classic US fourplex is a 2-story building with four apartments: two upstairs, two downstairs. First becoming popular when streetcars (also known as trolleys or trams) made suburbs possible, the fourplex offers choice for households who want to get out of the crowded city but can't afford or don't need a standalone house. Cross section of a fourplex . Before streetcars, city dwellers lived within walking distance of the city center. Few people could afford horses, so walking speed limited the physical size of cities. Adults walk at 2-3 miles per hour, which meant the largest ancient and medieval cities were just a couple miles wide. When population grew, cities would grow upwards, replacing houses with townhouses and tenements, 3-7 stories tall, built right next to each other with walls touching. Streetcars were invented in 1887 and could go much faster. Even with time waiting at traffi...

  Time period: 21st century Location: Within walking distance of a flagship state university Large apartments designed to be shared by roommates, plus amenities and retail. If you live in a college town, chances are you've seen a number of large apartment towers pop up on the skyline just outside campus. These massive buildings, the largest of which house over 1,000 students, might be called "luxury student housing" or "student containment blocks" depending on who you ask.  They are the result of a number of trends that started as far back as the 1970s and have converged today.  Unlike other apartments that often end up stuck with vacant retail spaces due to there being too much retail space relative to the number of customers, student housing has a high enough population density to support first floor retail. Dining, cafes, and bubble tea are common retail tenants, so the space should be built kitchen-ready. Enrollment Trends at Public Universities In the USA...

Time period: Late 19th and early 20th century, revived in 21st century. Location: Used to be everywhere.  Today: Seattle and New York City. A mid-rise building with a couple apartments on each floor.   In most cities, you'll find two types of mid-rise apartment buildings in the 4-7 story range. First, there'll be some small historic buildings downtown, side by side like books on a shelf. These are the original point access blocks. Then, there are the big modern buildings taking up a whole block and with long, windowless hallways inside. These are double loaded corridor buildings. Floorplan of a point access block.   Note that apartments have windows facing the front and back of the building.     In contrast, except for the corner units, apartments in a double loaded corridor only have windows facing one direction. Both the point access block and the double loaded corridor were designed to be the most efficient floorplan given the building codes of th...

  Time period: 20th century to present day Location: Suburbs In places that allow them, Accessory Dwelling Units are a way to have more than one home on a lot that is zoned only for one regular full-size home. ADUs are a second, smaller home (typically studio, 1-bedroom, or 2-bedroom) on the same property as a full size house. They're also called accessory apartments, secondary units, in-law suites, and granny flats. Hawaii calls them Ohana dwellings. In zoning and building codes, accessory uses are minor uses that are allowed as part of a larger project, even if the zoning or occupancy type does not normally allow it. An example of an accessory use is the manager's office of an apartment building, which is allowed in a residential zone even though it's an office use. ADU's are a similar regulatory reform to allow two homes on a single family lot, without changing it to duplex zoning. Examples of types of ADUs. Each type of ADU has advantages and disadvantages. Detach...

Examples shown are smaller buildings located in urban areas. Group living at suburban and rural colleges have larger yards and more parking. The largest sororities are found in the South, and have over 40,000 square feet of indoor space and are located on 1-acre lots. Time period: Mid/late 1800s to present Location: College towns Four types of student group living, separated by gender or economic system Key features - Located in clusters close to college campuses - Shared common spaces and bathrooms - In addition to residential uses, may also contain study halls and space for parties From the 1600s to the mid 1800s, college education in the United States was rare, limited to small institutions established by churches to train ministers. Liberal arts education was added in the 1800s. Enrollment was small - a couple dozen to a couple hundred students per college. In the mid 1800s, as the country grew and started to industrialize, there was a movement to expand higher education as farmin...

  Time period: 1950s-1960s Location: Los Angeles and other cities in the Western US 6+ homes and parking spaces, all on a standard house-sized lot, named after the fanciful decor tacked onto the front.  The dingbat was invented in post-WWII Los Angeles to meet the housing needs of a growing city as well as growing rates of car ownership. The standard 50' wide, 150' deep LA lot had been gridded out for detached houses, but many were zoned for low-rise apartments. Before the dingbat, the most popular types of medium-density housing were bungalow courts - a series of houses around a central walkway, as well as multistory courtyard apartments. In 1934, both types were banned by a new zoning law that required parking: one space per unit. Developers solved this math problem by turning the front yard into a driveway, leading to a carport that took up the front of the first floor. To maximize space, the second floor extends over the carport, propped up on stilts. This type of structur...
