Case Study-Jansen Court by CAST architecture
Single stair, 4 story (1 down) 10 unit studio apt, developed on the back half of a 30' lot.
The complexity of regulations are magnified on a small project, making it quite the puzzle. We are right up against nearly every code limit.
🚗There's a new lane in town and it's looking good!
This stretch of northbound I-5 near Seneca has been 2 through lanes since the freeway opened in the 60's.
Early this morning we finished restriping and debuted the 3rd through lane.
A move toward better mobility 🥳
Single stair buildings are critical to making new households on really tight urban lots feasible.
This is Echo on Eastlake-a 10 unit
#phius
passive house apartment we are nearly ready to send in for permitting. The lot is only 30x75!
Heard on a podcast that there are only 300,000 houses on the market in the US right now. Down from nearly 900K in 2018.
There are 1.5 million realtors. 5 times more than listings. Sure, some are commercial but it seems nuts.
you can't design a city based on what will not make drivers mad.
drivers are always mad.
it is central to the experience of driving a car, owning a car, parking a car, paying for gas.
If we used the billion dollars for a new west seattle bridge and invested it in housing and jobs, a hospital, broadband, parks and the local schools—I’d never want to leave my 15 minute neighborhood!
If we want to crack the housing crisis, ADUs aren’t enough. We need a repeatable adaptable accessible single-stair,

6/8/10plex that can be financed, permitted, constructed nearly everywhere on a margin that makes it more profitable than townhomes or detached homes.
I'm excited about what Spokane is doing to address their housing emergency: running a pilot to allow fourplexes through out the city. What I'm thinking:
We're developing a 6plex for Spokane. 950sf 2br/2ba flats w/2 affordable units.
This fits on any 50' lot and features big porches, daylight on three sides, high performance systems, extra storage, alley carport, and could be ported to other towns once HB1110 is implemented.
Dragging a 12 unit apartment with 4 accessible units for not having an elevator to the other 8 is divorced from reality.
If honestly you think every flat must be accessible via elevator, every single two story house should have one too, if the highest value is universal design
Lots of boring apartment buildings here in Helsinki.
But this is how you have 1) a cheaper housing market 2) enough people to make trams and buses frequent 3) viable ground floor retail and restaurants 4) lots of schools and parks.
Not every building has to be special!
Seattle infill challenge: 10 SEDUs on < 2000 SF-the rear yard of a turn of the century triplex. 4 stories w/ roof deck, 1 partially below grade, 1 stair. The building footprint is only 42x20.5', but the apartments are bright and open, and 4 have lofts! Builtgreen 4 star. FAR 1.32
Permit docs submitted for our little Spokane 4plex!
935SF 2BR/2BA units (1 affordable)
Heat pump
ERV fresh air
No fossil fuels/foam/fiberglass insul
Foamed glass aggregate insul sub grade
210sf of porch per
9’6 ceilings
4 new trees
Fits any 50’ city lot
I just filed this for permit in Spokane. This sixplex is a personal development project for me, my first. Big leap, but proof of concept for infill dev that is n’hood friendly, affordable, and high quality living, something we hope to export to Seattle once HB1110 is in force.
Why is modulation expensive? Orange: thicker floor structures : $$
Blue: extra wall framing, labor, roofing, flashing, fire protection, siding, sprinklers, drainage: $$$ and for what? Little decks you don’t use?
Seattle is changing, but we have the chance to design that transformation.
We need 200000 new homes in next 20 years, draw down car infrastructure/use, and to thrive with a low carbon lifestyle in midst of climate change.
How do we get from here to there? 1/
One of our cottage designs was selected by the City of Seattle out of 165 applicants. Sometime this summer, the design will be pre-approved for permit, meaning that we only have to complete the site specific zoning/land use/foundation in order to to get a building permit.
the building code in many EU countries today, still allows the single stair configuration to be built, and i think this is a really positive thing. it allows for the small, fine-grained development that makes cities so great. full block buildings are generally not great
Seattle, rather than arguing about will the neighborhood survive reintroduction of triplexes, look up at the smoke filled sky, breath in the ash & think about this happening every summer forevermore.
Now do you think we can get real about density, buildings, energy, transpo?
Sadly, we pulled the plug on the Spokane Four. We couldn’t get the construction budget to where it needed to be. The biggest line item extra was 87k in alley improvement.
Until we can find a better site and better financing options, the design will be available as a stock plan.
People seem to think that on a 30x75 (!!!) urban parcel you can develop a project that has:
Parking
Two stairwells
Elevator
2BR units
Below market rents
Less stories
Any one of those things would kill a small project like this.
Another sketch of why the 6/8/10 plex is the next logical step (not ADUs or townhouses).
Better land use
Great street presence
Efficient form and plan
Porch zone, big back yards
Flexible unit sizes including family size
Ownership opportunities
If we want to crack the housing crisis, ADUs aren’t enough. We need a repeatable adaptable accessible single-stair,

Evidence of SDOT car brain:
The planner who briefed the planning commission on the transpo plan’s lack of a defined vehicle miles travelled (VMT) reduction target told us:
“…You aren’t going to cycle 11 miles (into downtown)…”
My bike commute is 10.6 miles.
Seattle owns a massive chunk of land, almost 14,000 acres that it is barely using.
We should get together can come up with some ideas about how to best use this land!!!
Yes. A five way intersection with 6 lanes and four crosswalks. Lost tourists. Angry motorists.
Just a matter on time before someone is hit by a driver here.
The only consolation is that the streetscape is so hostile, people won’t want to be here at all.
Wondering how you’ll be able to use the new connection between the waterfront and Belltown whether you’re walking or rolling? Wonder no longer! These images show how you can use the new Elliott Way as early as next week.

Today in my UW housing design studio, we were presenting early prototypes to city staff, and of all the 130000 possible lots, a student randomly picked the one where the head of long range planning lives, proposing a nice 8 unit complex to replace his house.
Kinda brings it home.
Looking back, we did a very nice backyard cottage in 2017 for about $280/sq.ft.
Today we're seeing $600, $700 sq/ft for new construction.
Such as brutal fact for anyone looking to build.
I’m teaching a UW grad architecture studio on creative infill housing and 15 minute neighborhoods to meet the many challenges we face. We’ll be working with an eye for how innovative housing and a re-thinking the right of way can be the keystone in the
#OneSeattlePlan
Super fun!
We will go to any length to avoid building simple, nice small apartments with livable flats.
This is the housing that gets built right now, even though it
1) paves 80% of lot
2) has no space for trees
3) is super complicated
4) not accessible
5) carbon hog
because it pencils.
I got an e-bike last year. 1300 miles and counting.
Between gas, tolls and parking, I’ve saved about $727.
But I can’t put a value to the mental and physical health benefits. I just love it.
And if it were safer, more of us could enjoy it.
With any historic district designation you should at least have to give daily tours.
Think ‘Colonial Wallingford’
Watch a re-enactor pretend to be a historical figure, like a union Boeing engineer.
Since 1990, Seattle has permitted 190,789 homes (5611 /year). in today's boom times, we permit even more. Yet the
#oneseattle
plan is geared toward 80,000 units over 20 years, or 4000 per year. Really? With our housing crisis, our plan is to permit way less than we ever have?
Seattle is evolving as it grows. Now is the time for a new vision of how make room for housing and create the kind of city that we want.
What would be the next building block be if we started with some shared values and built a development pattern around them?
The Seattle Six
Just once I’d like to hear
‘hey, no one asked us to, but we just went ahead and made this bike lane extra wide, because all research shows that it is way safer and more efficient’
seattle's planning department asked people at community meetings where they wanted to see housing. they subsequently broke down "everywhere" into several categories to water down the response
so i fixed the chart
We’re losing another great employee to the housing crisis
@CMTammyMorales
Young professionals ready to start families but deciding they can’t do it here.
They’re moving to Duluth, Tucson, and Minneapolis.
We need more housing options now, middle class can’t afford Seattle.
Just because transit runs down an arterial does not make housing on that street ‘transit oriented’. Most likely it is just exposing residents to environmental harm between stops.
This is what planners want. This is what the Mayor wants.
As urban design, this is just sad for Seattle-no yard, no trees, no place to play, no place for aging or the disabled, all but 3 rooms look directly at neighbors, lowest energy/material efficiency, but for sale-fee simple
🚨 BOOM: The following housing types are now legal, for GOOD, in every single Spokane neighborhood:
– sixplexes
– lot splits with a 1,200sf lot size
– townhomes and rowhomes
– single-stair stacked flats
– cottage housing
Spokane is leading not just Washington, but the country.
So frustrating: testimony from a number of cities saying they have DONE ENOUGH on housing, when every indicator shows that we've underproduced housing for a generation, changing the climate in the process.
Let's face this problem head on.
Breaking down the State's HB 1110 draft Model Code, it is clear that how much you could build is too little to support 4 units as an alternative to single family development. We need more square footage, height, or lot cover to make these housing types actually work in the market
When I say Seattle needs a pedestrian square at the heart of every neighborhood, this is what I mean. Not the ridiculous stroad intersections we call “urban villages.”
There is roughly 4000 lane miles of street in Seattle.
How much is SDoT planning to convert permanently from car access to all the other priorities in the STP to meet climate challenge/safety priorities?
So far this year: 1/2 of one block, temporarily.
750 days
It takes 750 days to get through full Design Review—more that two years.
The Space Needle was conceived, designed, permitted and built in 400 days.
Why did Seattle permit only 4 townhouses in Jan ‘23?
Recap: Seattle’s inclusionary zoning (IZ)choices: build more than 5-11% units as affordable, or pay $9-43 per square foot into office of housing development fund. Varies across city.
Former single family zones (‘NR’) exempt
There is a mass transit technology that is faster and cheaper than gondolas, and I don’t know why we aren’t considering it: catapults.
Imagine getting in a padded car, flung across Elliot Bay, landing on or near a giant net by Lumen field.
Testing the State's Middle Housing Model Code against reality and realized that a modest apartment like our Spokane Six design would need to be 21% smaller.
Would a 21% smaller building (ie converting 2BRs to 1BRs) pencil?
No.
A year ago, Spokane decided to do something about their housing crisis, by letting people build 4plexes on single family lots.
The result:
410 new homes in the pipeline that might not otherwise have been developed
It is a cautionary tale for higher cost cities: if we can’t get a modest 4plex to work in a city with lower land/const costs plus higher than average rents, it is never going to work —until you go bigger—6,8,10,20 units. Just because you allow 4 units doesn’t make it viable.
Seattle’s townhouse production has collapsed as developers migrate to NR zones with no MHA fees and more parcels to choose from, to built duplexes and DADUs.
All home owners are investors speculating on rising housing cost.
When someone introduces themselves as ‘homeowner since <year>’, they’re stating their self-interest & status as investor class, not the depth of their community spirit. Different things.
We’re so close to breaking ground on this 6 plex in Spokane WA, but financing has been a moving target. If rates were at 5, we’d see hundreds of devs like this:
There is going to be a huge demand to fill for missing middle (2-20 units) developers as more and more cities realize the way to stabilize rents is to make it relatively easy to build
I think this opportunity exists across the country
I'm fleshing out just what the experience on the street would be like if we allowed six/eight/tenplexes with zero sideyards. The balcony buffer zone makes the reduced setback in front pretty friendly. Too friendly?

I want to highlight 4 processes happening right now in Seattle; each a fight for the future of a city, each an illustration of the perverse system we’ve built, where participation doesn't result in better outcomes. We’re left with Process, rather than results.
1/6
Frankly, we need to put less expensive housing where we have more expensive housing, so we can protect the least expensive housing from gentrification.
The next generation of development has to be distributed across the city, not just inside urban village boundaries.

Yes, here is our sixplex that we’ve designed for Spokane! Can’t wait to get it under construction! (6) 2BR/2Ba 1000SF family sized apartments, 2 are rent reduced thru MFTE.
The City is hosting open houses on proposed housing changes to the Spokane Municipal Code as part of the Building Opportunity for Housing project aimed at addressing the housing crisis. Open houses are TOMORROW at Central Library and Sept. 21 via Teams.
If you'd like to see what our residential zones could be, please check out this UW housing studio's work from 2022. Inspiring, fun stuff (and none of it allowed under current or future rules)

Seeing that housing was going to be too expensive for my own daughter to live in the n’hood she is growing up in now, the one we love, is part of why I started advocating for more affordable housing options.

Single stair point access blocks are flexible--here we got 72 apartments on several parcels, left a much more open site plan with a central commons, w/ 7000SF of ground floor commercial + a daycare. FAR of 2, 91% efficient floor plates, nearly 100 DU/acre.
I'm excited to say that I’ve been nominated to join the Seattle Planning Commission!
I’m going to go all out to focus our big picture planning efforts on
#GreenZoning
1 affordable housing options
2 equitable development
3 complete walkable n'hoods
4 fighting climate change
Too often Seattle zoning is driven by what we don’t want to see and therefore we’re stuck with unintended consequences.
Every weird thing about townhouses you hate is probably the product of a high minded attempt to regulate quality (and our super deep lot proportions)
This is big.
Washington State hasn't had a mechanism for holding cities and towns' feet to to the fire with regard to planning for the housing we know we'll need.
Now we will.

2) HB 1293--clipping design review
3) HB 1337-- bringing down ADU barriers.
4) SB5491-single stair apts.
Escalate your advocacy!
The problem isn’t that the stations are too deep or high—it is that they aren’t deep or high enough! With a little more escalator we could nearly eliminate the train segment altogether
Plans for the West Seattle and Ballard Link extensions include incredibly deep and high stations. These are very problematic for rider access and experience. Stephen Fesler argues that ST needs to take a mulligan and adopt new design principles.
Op-ed:
seattle, I'd argue that having a FAR of .9 in residential areas will not open them up to 4 units, but maybe 3 market rate ones. complying with the letter of the law, but essentially creating no new real capacity over today's SFR+ADU+DADU
#oneseattle
I want to illuminate why relying on additional upzones in the urban villages or tweaks to their boundaries is not the way forward given Seattle’s projected population growth and our current housing price spike. 1/8
