Stratum

For Architecture Firms

Your drafting board,
on the real site.

Stratum pulls a Boston parcel onto an infinite canvas with its real lot lines and zoning data, then gives you the drafting tools to work on it in real-world feet.

Sound familiar?

✗  Hunting down the lot lines and zoning data for a new site

✓Type a Boston address. The parcel lands on the canvas with zoning data attached.

✗  Sketching massing on a traced survey image that drifts out of scale

✓Sketch directly on the imported parcel; every line reads in real-world feet by construction.

✗  Flipping between a PDF viewer, a sketch app, and a measuring tool

✓PDFs, sketches, and scaled photos share the canvas. One zoom, one measurement, no exports.

✗  Measuring from a photo and guessing the scale

✓Draw one calibration line on any image. Every subsequent measurement reads correctly in feet.

Built for your workflow

Not another generic project management tool. Stratum speaks architecture.

📍

Real parcels, not traced polygons

Stratum reads the city's parcel database and draws the actual lot lines and zoning data onto your canvas. Setbacks and allowable envelope follow automatically.

📄

PDFs on the board

Drop a sheet, survey, or report into the project. Pages render on the canvas and in the viewer tab, so you work from the real document, not screenshots.

📐

Real-world feet, always

A sketch on a Stratum parcel is in feet. A line on a scaled photo is in feet. The canvas doesn't lie about dimensions; drafting discipline is enforced.

∞

Everything on one board

Parcel, PDFs, site photos, massing sketches, measurements. One infinite canvas instead of three tabs and a measuring app.

Layers of insight. One canvas.
