A little clarity. A better build.
Building Assistant brings your everyday construction and site-planning calculations into one thoughtfully designed workspace. From the first sketch to the final pour, keep the numbers close and the work moving.
A TOOLKIT FOR REAL WORK
Explore 118 calculators across construction and urban design. Estimate concrete, reinforcement, masonry, finishes, earthwork, formwork, roofing, tanks, and waterproofing. Work through floor area ratios, site coverage, parking, and more.
SEE THE RESULT AS YOU WORK
Enter your measurements, choose metric or imperial units, and see quantities update. Clear unit labels, waste allowances, and visible formulas help you follow the calculation.
GIVE EVERY PROJECT A HOME
Keep your calculations with a project, add client and site details, and save the notes that matter. Search your history, star useful results, and reuse previous inputs without changing the original record.
GOOD WORK, WELL PRESENTED
With Pro, turn calculations into clean PDF reports with your company name, project, inputs, results, and site notes. Preview the report before sharing it.
READY ON SITE
Calculations, projects, and history work offline. No account is required. Your work stays on your device, with backup export and import when you need to keep a separate copy or move devices.
MAKE IT YOURS
Choose from five architectural color palettes, with light, dark, and system appearance.
