The pipe is already in the ground
Streets, sewer, water, power
A greenfield site asks a city to build new infrastructure and then maintain it forever against the tax base of one subdivision. An infill site asks for nothing it does not already have. The same block, built on, pays for the same pipe twice over.
A block with a gap in it
The street wall
A missing building does not cost a neighborhood one building. It breaks the line of the street, and a sidewalk with a hole in it stops reading as somewhere to be. Filling the gap is what makes the buildings on either side work again.
The schools are already built
26 closed in one night
In March 2010 the Kansas City school board voted five to four to close 26 schools, close to half the district, with enrollment down to roughly a quarter of its late-1960s peak. The buildings did not move. Housing within walking distance of a school that is still open is the cheapest enrollment a district will ever get.
The bus already runs
Troost, Prospect, Main
Frequent service on Troost and Prospect, the streetcar on Main. Adding households on a corridor that is already served costs the transit agency nothing and improves the economics of the route. Adding them four miles out does the opposite.
New, but not a stranger
Scale, setback, the front door
Infill does not mean imitation. It means a building that holds the street line its neighbours hold, meets the sidewalk the way they do, and puts its front door where a front door goes. Do that and the architecture can be entirely of its own time.
The entitlement is the project
Neighbourhood meetings first
Urban renewal areas, abatements, rezoning, and a public meeting where people who have watched promises come and go want to know what you are actually going to build. We design through that process rather than around it, because the drawings are what the room is reacting to.
