new block-sized development in stuttgart.

what do you see?
alright.

2 things.

1. i was going to do a thread on this development, compared to the US - and why we could not replicate that here...

i totally did not see the thing. incredible.

2. this *is* 'density done nicely' (h/t @edjegasothy)

twitter remains undefeated.
this is the olga areal in stuttgart. it's a pretty big block, the area bounded by the buildings is roughly 310' x 410'

the buildings themselves are only about 12m (40') thick.

this is incredibly thin by US standards. we routinely hit twice that on new buildings in seattle
these are both new 4-6 story developments.

what are contrasts between olga areal (l) v. seattle (r)?

building thickness?
open space?
lot coverage?

what about things that aren't visible?
affordability?
unit mix?
social & economic mix?
the areal is made up of 4 different baufelder (building areas) consisting of a pretty wide swath of building types.

you have social housing, upper middle class housing (baugemeinschaften - self-developed urban housing), and investor (market rate) housing.
the red numbers are lot coverage of the individual buildings - ranges from 35% to 63%.

and yes. buildings. plural. 13 total.

in seattle - this would be one developer, maybe two. but typ. approach is just one ginormous building.
the angle on left is 1 building. the ]-shaped building on right is another. there are 4 in the middle, including two that are joined but freestanding.
if these buildings were all as thick as we see in seattle, there would be almost no open space - and if you scroll back up - you might notice that the seattle projects have almost no open space.

tiny courtyards.
the thing that allows these buildings to be thin?

they're all point access blocks. single stair buildings. common the world over, outside of the US and canada.

more on PABs here: larchlab.com/point-access-b…
most of units are 'durchwohnen' - through running w/ daylight on multiple sides. the ability to cross ventilate.

this typology also allows for a larger diversity in unit types. these have units from 1-4 bedrooms in them.

similar to this.
there's quite a bit of diversity in unit types and sizes in the olga areal. flats. maisonettes.

there is more economic and social mixing than you would typically find in seattle dev as well

and all those smaller buildings?

they make for a much better walking environment
our land use codes pack in nearly twice the FAR (buildable area) as most european cities for low and mid-rise.

and our US building codes don't allow point access blocks...

the result? massive buildings w/ a corridor down the middle of the building, with units on either side.
in US development - there's little unit diversity, as our regulations result in a system that effectively mandates lots of small units, instead of inducing larger ones.

there's typically not much economic diversity, either - at least not at the level and scale of olga areal
i expand on this quite a bit in my thread that came out after the recent new york times piece on why massive buildings in the US all look the same:
this diversity in building types allows for a lot more creativity on the design side as well (and more work for more firms, too)

the utilization of baugruppen in this project is also great. there is even a stunning mass timber project (maxacht) - set to the interior of the dev.
the architect of that project is architekturagentur.

it's a great little project.

architekturagentur.de/geplant-gebaut…
these buildings are also better able to withstand effects of a warming climate. they have active solar protection. they've got the ability to cross ventilate.

the block itself is semi-permeable - allowing better airflow than a closed block w/ small courtyard would allow...
the project includes daycare, community spaces, shops/cafe spaces. grocery store...

and just look at how massive these courtyards are.

you could not replicate this development anywhere in the U.S.

not too shabby.

bollard: i only regret that I have but one life to lose for your podcast Image
these guys would likely have died if the bollards had not been installed.

pretty terrifying.

when will cities take this issue seriously?

german building & land use codes allow multiple point access blocks, no modulation req't.

the result: family-sized homes. dual aspect homes w/ light on multiple sides, cross ventilation. larger courtyards. better mix of homes. more energy efficient & cost effective buildings
this is true for small lots, and even large developments like the stunning project in hamburg above.

seattle's building code is pretty much the opposite. mandates double loaded corridors w/ absurd amounts of FAR and building code restrictions not found in majority of countries
this means in the typical mid-rise development in seattle - our floor plates are *considerably* thicker than anything you would see in german housing

our unit mix is skewed towards studios/1BRs.
miniscule courtyards, units looking into each other.

blrm architekt*innen's pergolenviertel in hamburg is gorgeous

a perimeter block w/ large courtyard.
(8) point access blocks
mix of unit sizes and types: townhouses, flats from 1-4 bedrooms
most units dual or corner aspect...

architizer.com/projects/pergo…
this corner features a 4-bedroom unit w/ light on 3 sides.

you'll never find that in the US...

total floor plate thickness of about 40' - this is nearly *HALF* as thick as floor plates in double loaded corridors in seattle. this is what allows for the massive courtyard. Image
oh wait - that corner unit is a FIVE bedroom home.

again... good luck getting that anywhere in seattle. Image

nearly got clipped in sidewalks at opposite ends of the same block by cars turning.

it's not dark out.

educating motorists isn't going to fix this.

where's that #VisionZero review? what is being excised from the report?
dying
wow

same crosswalk on walk back, car refused to stop for a mom in the intersection and nearly hit them.

yes. when i requested a neighborhood walk with spotts almost 6 months ago, it was one of ones i highlighted. SDOT only fixes something when someone dies

'how can single-family houses, both new & existing, be (re)designed and adapted to the life cycle and changing requirements of the residents?

how can you react appropriately to the challenges of our time with this design?'

questions @WuestenrotStift asked for its design award
i want to highlight 2 of the announced winners here

because i think both of these projects are incredibly poignant, and timely.

more importantly, they foster an interesting dialogue about densifying cities and villages...

baunetz.de/meldungen/Meld…
the first is wolfgang zeh's slot infill house in koeln.

site for this is moderately urban. a whopping 11'-6" wide. it was formerly just a garage between two multifamily buildings.

now it's a home for a family, w/ workspace as well.

love to hear my wife almost got hit biking northbound in the 'protected' bike lane on greenwood, as a motorist turned southbound on to east green lake way, floored it to hit gap between cars, and veered into the bike lane because they were going so fast.

ironically:
i knew as soon as this was installed that putting cyclists and oncoming traffic just 2 feet away with nothing between them but a piece of government plastic was never a good idea.

this is why we need people who bike designing bike infrastructure.
bollards or bust
