Parking opportunity scanner

See which parking lots could become city blocks.

Lot2Block maps surface parking across 51 US downtowns with the buildings, transit, flood zones, and market data around each lot. Then you can sketch a reuse scenario on the same ground and see the numbers behind it.

One site, two readings

Drag from today's lots to a sketched alternative.

Both frames come from the same camera in the 3D site builder, over four Pittsburgh blocks. Left is the mapped parking condition; right is one illustrative mix of housing, planted space, and retained parking. A scenario is a sketch to test, not an approved design or a forecast.

How it works

From a city map to a site scenario in three moves.

Each step stays tied to the lot you selected, and every number on screen says where it came from.

  1. 01

    Pick a market

    Choose one of 51 cities. The scanner loads its mapped surface lots, colored by estimated demand, along with streets and buildings.

  2. BuildingsTransitFlood
    02

    Read the context

    Turn on transit, flood zones, parcels, permits, and nearby businesses one at a time. Every layer carries a legend and its source.

  3. 03

    Sketch a scenario

    Open a lot in 3D, arrange towers, housing, and green space, and see a cash-flow screen built from live rent and rate data.

Walk-around

Walk the street before anyone builds on it.

These are actual Lot2Block captures, not concept renders. The skyline appears only where the app's 3D city context rendered it.

Read the site against its skyline.

The app-rendered Center City context places the street, pharmacy, proposed building, and recognizable skyline in one pedestrian view.

Check frontage and building variety.

Walk along the block to compare active ground floors, street trees, transit, existing buildings, and new massing from eye level.

Follow the transit approach.

Street-level movement makes the relationship between a site, its transit stops, road space, and the surrounding skyline easy to inspect.

Compare façades across the street.

Orbit and walk views show how planted façades, open space, and building height sit against the existing block.
