The Art and Science of Measured Space
Behind every successful portfolio is more than data — it’s the discipline of precision. Stevenson brings together decades of expertise, unrivaled accuracy, and next-generation portfolio-wide analytics to reveal opportunity where others only see floor plans.
This is how space becomes strategy.
Building Measurement vs. Space Accounting
Space Accounting transforms raw square footage into actionable portfolio intelligence.
Your company has acquired thousands of square feet of Class A office space and potential occupants are lining up. Or maybe you’re assessing an acquisition opportunity—a high rise apartment building or premium retail park. Whatever your real estate investment, the question is, “How can I be sure if I’m getting the most out of every square foot?”
As-builts are vital, and there are many ways of obtaining them, from architects (who look at the data from a design perspective) to specialist as-built providers (who supply measurements and plans). Typical building measurement companies will deliver other services you might require: precise measurements, reliable documentation, and advice on applying measurement standards. But building measurement is not enough. It takes a Space Accountant to unlock the value hidden in your assets.
Stevenson Systems provides the fundamental services, executed to the most exacting standards, but that is just the beginning of maximizing the value of your assets. Beyond building measurement, Stevenson Systems delivers a customized strategy to maximize the value of an asset and mitigate risk. Stevenson Systems continually unlocks and protects value in your assets through dynamic access to building and occupant related data throughout a property’s lifecycle.
