Affordable by Design: The 4-Over-1 Revolution

Affordable by Design: The 4-Over-1 Revolution

When we think of iconic urban growth, towering skyscrapers usually steal the spotlight. But behind much of our city’s real boom was a quieter hero: the four-story stick-frame condo. It isn't the tallest buildings that changed our city—it is the smartest ones. Meet the 4-over-1, the unsung hero of housing.

Known in the industry as a “4-over-1,” these buildings were smartly designed—a concrete first floor (often for parking or retail) topped by four levels of cost-efficient wood-frame homes.

The magic?

  • Lower construction costs without sacrificing urban density.

  • Faster build times that kept housing supply moving.

  • Real affordability for downtown buyers and downsizers who didn’t want a 3-acre lot.

Today, many of the most beloved urban neighborhoods owe their energy—and their accessibility—to these humble, hard-working designs. They weren’t just buildings. They were opportunity, built one floor at a time.

This building showcases a smart construction method: a main level of steel and concrete with a four-story wood-framed structure above. Efficient, cost-effective, and essential for building attainable housing in today’s market.

Here’s the real, no-fluff truth:

Building Type

Cost Per Square Foot (national average 2024)

Notes

4-Story Stick Frame (over concrete podium)

$165–$225/sf

Most affordable for density. Common for mid-rise condos, apartments. Good urban-suburban crossover.

Mid-Rise (Concrete/Steel Full Build)

$300–$400/sf

More durable, but way more expensive—used in bigger downtowns.

High-Rise (Glass Curtain, Steel Frame)

$500–$750+/sf

Sky-high costs. Reserved for major metros.

Garden-Style Apartments (2-3 Story Wood Frame, No Elevator)

$140–$180/sf

Cheaper than mid-rise, but density is lower and land costs matter more.

Why 4-Story Stick Frame is the “Affordable Champion”:

  • Wood is cheap compared to steel/concrete.
  • No super expensive elevators/engineering needed (only basic code compliance).
  • Build faster (wood goes up like LEGOs compared to steel).
  • More density than townhomes or garden apartments = spread out land costs better.
  • Appeals to downsizers, first-time buyers, and investors = huge market audience.

Real world:

Your downtown or urban-edge 4-story condo buildings with underground/covered parking?

Those are almost certainly the most cost-efficient and affordable per-door developments.

And ironically, now that construction costs are insane, they’re still some of the best “legacy” projects because they deliver a market rate product without being government subsidized. So the next time you dismiss a 4-over-1 building as just another symbol of gentrification—and sure, sometimes it is—remember this: it's also the most cost-effective way we have to build more housing at attainable price points. If we want real solutions, we can't afford to overlook the tools that actually work.
