Hey —
I'm Edgaras, co-founder of OakSheet.
Last year I built my own house. Not as a contractor — as a first-time builder who hired subcontractors and managed every detail myself. Lumber, hardware, labor, permits — all tracked in spreadsheets that got messier with every revision.
Now I'm building a shed, a grill zone, and a sauna. And I keep seeing the same pattern: the same materials and the same assemblies show up across every project. A deck frame here, a roofing section there, the same hardware list over and over.
Yet every time, I was estimating from scratch. Copy-pasting between spreadsheets. Forgetting waste factors. Second-guessing my own numbers.
So I built OakSheet — first for myself. A place to store my resources once, build reusable assemblies, and drop them into any project. Quantities, waste, markup — calculated automatically.
It's still early. We're building this in the open, and every feature comes from real projects and real problems. If you've ever stared at a spreadsheet wondering if you forgot something — I built this for you.
We'd be honored to have you try it.
From resources to finished estimate — three steps.
Materials, labor, equipment, subs, fees — each with its rate, unit, waste factor, and markup. Add it once, use it forever.
Combine resources into components you use across projects — a deck frame, a base cabinet, a roofing section. Build it once, drop it anywhere.
Create a project, add your assemblies, adjust quantities. Waste, markup, and totals calculate automatically.

Resource library
Add your materials, labor rates, equipment, subs, and fees to a central library. Set waste factors and markup per resource. When prices change, update once and every estimate reflects it.

Assemblies
Group resources into reusable assemblies — a deck frame, a cabinet box, a bathroom rough-in. Assemblies are your building blocks.
Assembly editor view
