Owner-side tools for building, renovating, and running a home — from a licensed architect.

A renovation budget built the way an architect phases a project — by trade, in build order, with room tags. Contingency held on top, planned-vs-actual variance, contractor-quote comparison, and a payments log that knows what you still owe. Five tabs, pure formulas, no macros.

The three records every house should have: a maintenance schedule with a live due engine (45 curated tasks — roof, envelope, mechanicals), an insurance-ready home inventory with replacement value by category, and a service log that proves the house has been cared for. Four working tabs, pure formulas, no macros.

Cost control for building a house: sixteen phases from sitework to landscaping, budget → committed → actual → forecast on every line, a construction-loan draw log, and the out-of-pocket number owner-builders feel but rarely see. Five tabs, pure formulas, no macros.
