definitely wouldn't want to live on a car-light street lined with 5-story buildings, like this dietrich untertrifaller proposal for freiburg's dietenbach... Image
btw this was a staedtebaulicher wettbewerb (urban development/planning competition) that was won by k9 architects w/ latz landscape architects

freiburg.de/pb/495838.html ImageImageImageImage
it's situated to the north of the rieselfeld district, at the edge of the city. the site is actually a greenfield - so there's been a lot of discussion and engagement on how to develop here. the city has some really incredible goals here. Image
this will be a large district - 270 acres. 50 of which is open space. 6,500 homes for 15,000 people. sports fields, gardens, kindergartens, schools, sports facilities, shops, cafes/restaurants, space for offices... and connected by tram and bike path to the altstadt
the district is intended to be urban, green, and socially mixed. there will be an incredible diversity in housing types and affordability here - like those i recently discussed in this housing thread:
the framework plan, released last nov. - expands on how those themes will be met, how streets will be laid out, the urban form designed by the planners... unlike in the US - where pointless land use regs dictate form, divorced from pretty much everything

freiburg.de/pb/site/Freibu…
the planning takes open/semi-permeable perimeter block as the starting point. it is also broken into smaller quarters. this helps neighborhoods build identity/solidarity within a larger context. the core will feature taller/denser buildings and a larger plaza for markets/fests Image
this semi-permeable/open perimeter blocks allow for green space to the interior, but also play into the climate adaptability of the district.

as we should be doing with every project - simulations have been studied with present and future climate changes

freiburg.de/pb/site/Freibu… Image
housing typologies - rowhouses, maisonettes, terrace houses, small apartment buildings, baugruppen...

most of district is 4 story bldgs , w/ 5-6 stories along major road to NE, and the core/tram line in middle. there are some point towers for accentuation/orientation as well Image
each quarter has it's own square for gathering. in this overview, this platz surrounded by a community center/kindergarten, shops, gastro... and adjoining blocks also have kindergartens. why should you have to commute 30 minutes or more to drop kids off at daycare? Image
on top of anticipating how climate change will affect the district - it is also aiming to be climate neutral. buildings will be compact, and passivhaus(ish - very low energy). there will be ample on site production w/ roof and facade PV.
it will feature car-free and traffic-calmed streets with ample trees and greenery...

imagine if a single street in seattle was planned like this

just one Image
lots of green space...
lots of trees...
and still, a ton of housing. Image
the dietenbachaue is a 24 acre park/biotope that will play a part in stormwater management - as well as bringing fresh, cool air into the district.
and promenades on either side...

there are very few places in seattle where multifamily housing is directly accessible to massive parks like this (by design, unfortunately) Image
and virtually all of the housing (remember, mostly starting at 4 stories) is located within a 500m walk of one of the three tram stops.

in seattle metro, we step down to detached houses within 200m of most *light rail* stops. Image
freiburg was where i fell in love with cities (and more importantly - my wife!). and bikes. and trams. and trains. and the duality of nature adjacent to density.

we don't have any of this in seattle. at any level.

and it is a large part why we keep whiffing our climate goals
this is how you create dense, walkable districts around transit. we're building ton of light rail - but there is ZERO planning for anything close to this.

we have a lot to learn before we can crawl, let alone walk

dietenbach's framework plan is here: freiburg.de/pb/site/Freibu…
you can catch the competition's placing proposals in this report freiburg.de/pb/site/Freibu…
k9's competitions boards can be downloaded here: freiburg.de/pb/site/Freibu…

will never understand why SDOT is so bad at planning and future-proofing for sustainable mobility

the dexter & thomas protected intersection is an expensive case study in how to prioritize cars instead of sustainable mobility, through poor planning
Image
and nearly every other intersection on dexter is an absolute sh*tshow

having one poorly planned protected intersection doesn't change that.

the poor network is the problem, and directly related to why seattle's bicycle mode share has remained a flat 3% for over 30 years.
if we actually made cars do what SDOT is making bicycles do at this intersection in more of the city - we might actually meet our vision zero goals

unfortunately, this design fails to prioritize sustainable mobility. the bike lane is too narrow, and not adaptable to higher usage

thinking about how wildly different quality of new 1-BR units are in US v. germany...

seattle (l): double loaded corridor. 800 sf. 36' deep. windowless BR. 1 window (!)

munich (r): point access block. 650 s.f. windows for BR/bath, k/d/l. ~16' deep. + 110 sf balcony.
Image
Image
that character carries through to the interior. radically different quality of living, of daylight, of privacy in many cases as well.

again, seattle (l), v munich (r)


Image
Image
Image
Image
can you imagine a 1 bedroom apartment with light on 3 sides?!?

twinned point access block w/ units from 1-3BRs.

what is the cost of FAR wasted in townhomes?

30% of calc'd FAR of this back to back townhouse project is just... stairs

codes & regs & financing & poor construction quality make flats impossible at this scale

it's not insignificant. it's 1,300 s.f. Image
the opportunity cost of 4 separate townhomes over flats is basically an additional 3-BR unit.

imagine paying $850k for something like this - and knowing a third of your mortgage is just paying for stairs.

literally the dumbest sh*t i've seen in a minute.
this is exactly what harrell's comp plan is designed to induce.

it's not going to be affordable. it's not going to be accessible. it's going to continue to decimate biodiversity. it's going to reduce climate adaptation.

we're going backwards

i've given a number of talks about how poor quality of life is in US multifamily housing, and it's a central theme of my book...

a >1,400 sf 2BR with only 2 windows and none in the common area and one bedroom home is a first.

this is where building codes are headed in the US. Image
double loaded corridors. no limitations on building depth. absurdly high FAR. 50' dead end corridors.

this is where the IBC is headed. multifamily housing in other countries doesn't look anything like this.

and mass timber doesn't fix this problem.
quality of life in multifamily homes should not be substantially lower than that of detached houses

yet that is *exactly* what US building codes induce.

it isn't like this in other countries.

without substantial change (legalizing taller point access blocks) it'll get worse

car free streets. hundreds of businesses. how do they even survive?

Image
Image
Image
the answer?

early morning or late night deliveries

deliveries by bike, scooter or hand cart

density isn't limited to a block or two off the street but continues forever

no single family zoning

pedestrian priority

mixed use zoning

point access blocks w/ small footprints
we've eaten at several incredible places that have at most 10 seats

the abundance of buildings with minuscule footprints allow for a ridiculous amount of commercial diversity on ground floor (and above/below)

i should do a thread on elevator to unit ratios in other countries...

i'll start with this one, just because it's pretty low:

basel (CH)
(8) elevators in (2) 3-story buildings, serving just 48 units.

elev to unit ratio: 1:6

baudokumentation.ch/projekt/wohnen…
the stunning swiss coop in this thread

basel (CH)
(12) elevators in (12) connected 5-story buildings, serving 125 units.

elev to unit ratio: 1:10.4

luca selva's wohnueberbauung densa park

basel (CH)

(8) elevators in (2) 5-story+ DG buildings, serving 99 units.

elev to unit ratio: 1:12.4
