A short thread on going beyond #NetZero to build projects that are #NetPositive
First, I like to talk about "Projects" vs "Buildings".
It's an important distinction, because its not just about the physical artifact, but also:
where it is located?
what does it replace?

So, remind me again, why we are paying 3x per capita for policing in Vancouver?

Further exploration of single-stair stacked flats, with external stair.

Roughly 2.0 FSR. 90% Efficient.
18 small units and 12 larger units.
All units are "corner" units.
In this version we're exploring wrapping the stair around a CLT elevator core.

Here are stacked flats, 6 storey single stair, combined with 3 lane fronting townhouse units to make a courtyard space.
70'x122' lot.
We're trying to see if this approach can compete with the typical Vancouver RM-4 building that would completely fill the lot and have more units.

Not enough people are talking about how Michelle Wu is so popular in Boston, her general election opponent just stopped campaigning after the primary. That’s wild.

No cuts until the next election.
This is crazy city management. If you have an election mandate for cuts, then fine, but tagging this on now - seemingly on a whim - is trumpian in it's wanton destruction.

Vancouver recently adopted a plan to create simplified apartment zones in parts of the city (broadway and cambie mostly).
We've started looking at what might be possible with single-stair buildings.
Here's an R3 zoned site comprised of two 33x100 lots.
The zoning allows ~2.2FSR and six storeys.

As a zoning rule to manage floor plate depth I’d suggest: “There shall be no interior point less than 7m (23’) from an exterior wall that is not a party wall.”
The language would have to be massaged, but in theory this would allow a range of floor plans with a max plate depth of ~46’.

So, we need our political leaders and planners to take the lead.
I know it's difficult moving upstream against the status quo, but that's what we need if we want to make a dent in the housing and climate crisis, and create green, accessible cities in the process.
