The lineup · Three Cascade peaks
Helens. Adams.
Rainier.
Three plans named for the volcanoes you can see from Tacoma. Helens is the smallest — 660 sf 1-bedroom, the short-term-rental specialist. Adams is the workhorse 2-bedroom at 840 sf. Rainier is the flagship, built to each county's legal cap. Pre-approved drawings sit on file with Pierce County, the City of Tacoma, King County DLS, and Thurston County. We don't redraw your DADU. We build the one that already works.
Plan 01 · Helens · 8,366 ft
The Helens
660 sf · 1 bedroom · 1 bath
The smallest plan in the lineup. 15×44 shell, vaulted ceiling, full kitchen, walk-in shower, true 1-bedroom layout. Built for short-term rental income, a clean office-with-bath setup, or a starter long-term tenant. Named for Mt. St. Helens — smallest of the three peaks, the one that famously blew its own top.

The Adams

The workhorse. Two real bedrooms, full living room, dedicated kitchen, full bath. The build that pencils on the most lots and lands a long-term family tenant — the one most of our clients pick first. Named for Mt. Adams, the quiet middle child of the Cascade peaks.

Two ways to spec an Adams
Best $/sf in the lineup.
2-bedroom workhorse.
The Adams tier runs on Karsten's Dream series — the best price-per-foot we can deliver at this size. The 562N is a tight 15×56 ranch; the 661N stretches an extra 10 ft for a larger primary suite, a real second-bedroom closet, and the option to add a half-bath. Both are 2-bedroom builds with the same factory line and five-month timeline.

The Rainier
Scales to each county's legal cap
The flagship. Two real bedrooms, two full baths, dedicated laundry, an open great-room kitchen with a full island, and a vaulted living space that runs the length of the unit. Standing-seam metal roof, board-and-batten with cedar-accent entry, stone skirt, covered front porch. Built to a third bedroom in its larger trim — same factory pipeline, same finishes, same five-month timeline. The most home we build, dialed for a long-term family tenant or a sell-it-solo condoized exit.
Standard inclusions (all variants)
- Two full baths — primary en-suite plus a guest bath
- Real bedrooms with full closets, all fitting a queen + dresser
- Open living / kitchen with island, dedicated dining area
- Full-size laundry room (W/D included)
- 9-ft ceilings throughout, vaulted in living room
- Larger covered porch and dedicated parking pad
- Heat pump mini-split, ERV, smart thermostat
- Sized exactly to your county's legal cap — not a square foot wasted
Two ways to spec a Rainier
Long-ranch or wide-bay.
Same legal cap.
Both Rainier variants land at the legal max for Pierce, King, and Thurston. Sweet Caroline runs a narrow 15×76 long-ranch — the cheapest $/sf in the entire lineup, fits skinny urban lots, lays out as 2 bed in Pierce or 3 bed in King & Thurston. The Dream 441F goes wide-bay at 27×44 — same square footage, a more compact site footprint, and a true 3-bed layout with a real kitchen island.
