the KPOe in graz pushed for the land at the hummel baracks (hummelkaserne) to be used for social housing.

there is now a massive mass timber passivhaus complex by sps architekten there

also this mass timber stunner of a cooperative in graz... holzbauaustria.at/architektur/20…
just random thoughts related to this...

it's interesting to me that in the US, we're adding new apartments at the ground level of existing buildings - because in such poor foresight, this area was space for cars.

whereas in DE/AT - they're adding new apartments above the existing roof level, even in newer buildings.
there are some really intriguing projects by @OpenScopeStudio/@markasaurus that have been infilling multifamily ADUs in former garage/storage spaces. openscopestudio.com/multifamily-ad…
but in built up cities that aren't dominated by detached houses - there's a lot of potential for new housing.

TU darmstadt study found that an additional 1,5 million new homes could be added to existing buildings by vertical additions (aufstockungen)

bungalow courts were common until the 1930s - because cities either had no zoning, or very liberal zoning (compared to today, at least), at that time.

land costs were v, low. little to no parking req'd. incredibly inexpensive, low-slung building forms.

we even have some in seattle. this one (10) 1-BR/1 Bath, 450-560 sf condos on what are 2 parcels. built in 1917, this project predates 1923 zoning ordinance. recent units sold for $450k. whole dev is ~$4.5M today

you'll be shocked to find these were downzoned to single family. ImageImage
it was *exactly* these types of projects that zoning was introduced to stop the spread of.

here's a pro-zoning poster from seattle from 1922- - when the zoning ordinance was being written/edited by apartment-hating, car loving, exclusionary zoning devotee harland bartholomew Image

does the city of seattle actually have mode shift goals or targets? are we anywhere close to hitting them?

the city of freiburg has halved number of trips by car - and as they add car-light ecodistricts and densify city - this shift will keep increasing
freiburg grew by 20%, & reduced CO2 emissions per capita by a third, since 1992.

bike infra investment
transit investment and prioritization
pedestrian zones
re-compaction and car-light ecodistricts
investment in green energy

seattle's CO2 per cap has been flat for last decade
city of essen's mode shift goals

so a few months ago, i was interviewed by @Quicktake for a documentary on social housing in vienna.

vienna is doing so many things right on housing, on climate, on transportation, and on land use.

we should follow suit.

enjoy!

4 years ago over on @CityObs i wrote about housing lessons seattle and other cities in the US should take from vienna, after visiting for the passivhaus conference in 2017.

cityobservatory.org/housing-policy…
at that time, i wrote,

'our zoning, our lack of vision and leadership, our lack of comprehensive planning, our lack of innovation, and most importantly, our lack of funding make such a model difficult'

4 years later, this is still true.

we have some 1.5 million people that are expected to move to the puget sound region by 2050

where are they going to go?

how can they be absorbed without adding 100ks of cars?

going to need a sh*t ton of car-free spaces

and streets where *mobility* is prioritized, over cars
and yes, that will mean we need to rethink what our streets look like in a *massive* way

there are a number of reasons why @pushtheneedle pushed vision for a car-free aurora

theurbanist.org/2021/09/16/env…
a number of those reasons are already in this thread:

but i'll add a few more
