The builder that starts with a diagnosis.

We find the changes that make your people healthier and more productive — then build them. One accountable team, from diagnosis to measured result.

BUILT TO PERFORM

Companies aren’t renovating offices to refresh finishes anymore. They’re solving real business problems — bringing people back, recruiting and keeping talent, lifting engagement and productivity.

Most firms only do half the job: consultants assess your space and hand back a report, and contractors build whatever someone else already drew. Five Stones does both — we diagnose what will create the most value, then build it.

Where we start

THE WORKPLACE PERFORMANCE DIAGNOSTIC

Before we recommend a single change, we read two things — your people and your building.

Employee experience

How your team actually experiences the space: collaboration, comfort, satisfaction, productivity, and wellbeing.

Building performance

An on-site, instrumented assessment of indoor air quality, lighting, acoustics, thermal comfort, and how the space is used.

Together they produce a prioritized, budget-aware plan — the changes that will move the needle, ranked by value. The diagnostic is a paid engagement, and the full fee is credited toward construction if you build with us.

What we build

FIVE SYSTEMS OF A HEALTHY WORKPLACE

AIR

Better filtration, ventilation, and live air-quality monitoring.

LIGHT

Circadian and tunable lighting, and better daylight access.

SOUND

Acoustic comfort, focus rooms, and sound masking.

NATURE

Biophilic elements, living walls, and natural materials.

MOVE

Sit-stand workstations, ergonomic furniture, active spaces.

We package these into three levels — Foundations, Performance, and Signature — so you choose an outcome, not a hundred line items. We specify and install through a vetted Performance Alliance of the makers doing this best.

Why Five Stones

WE DIAGNOSE, BUILD, AND PROVE IT

  • Diagnose before we build — every recommendation is backed by evidence.
  • Credentialed judgment — Fitwel, WELL, and LEED-informed standards behind the work.
  • One accountable team — strategy, coordination, and construction under one roof.
  • Measured outcomes — we come back and verify the result.
