Why we ask

Your address is the input the MAVI 129™ framework uses to score your home environment. We pull eight live data sources (air-quality stations, water-utility records, satellite light-pollution data, ambient-noise modelling, and others), and return a four-pillar Snapshot of your home with an estimated MAVI Score, delivered to your inbox.

A measurable specification for the home, graded across ten domains and 129 cited factors. Enter your address to begin an assessment.

Where you live is a first order
determinant of healthspan.

We spend more than ninety percent of our lives indoors, yet the spaces we inhabit are rarely designed for the body that lives in them. MAVI translates peer-reviewed longevity science into a performance specification for the residence, ten interconnected domains, 129 cited factors, every claim sourced.

Does your home need a doctor?

The Financial Times profiles the emerging discipline of longevity architecture, with Kas Bordier, Kelly Hoppen CBE, Shouka Amirsolimani and Dr Tamsin Lewis. Methodology, pricing, and the live projects across London, Switzerland, and the Pacific Palisades.

Longevity architecture should become a standard for the industry, with people looking at the health rating of the space the same way as the energy rating. Kas Bordier, founder, MAVI

Inside MAVI Longevity

Most luxury homes look healthy.
They are not.

Sealed windows. LED that destroys melatonin. Materials that off-gas for years. Ventilation designed by accountants. MAVI residences are different. Not because they are more expensive. Because they are more intelligent.

  1. 129
    Measurable health factors Particulate matter, light spectrum, acoustic reverberation, off-gassing chemistry.
  2. 10
    Interconnected domains Air, water, light, sound, temperature, materials, microbiology, technology, mind, habits.
  3. 90%
    Of life lived indoors Yet most residences have never been measured for the body inside them.
  4. 60%
    Reduction in inflammatory load Longevity that moves the needle, not expensive noise.
  5. 10+
    Years of research Across longevity science, behavioural design, environmental biology, and building science.

Inside a MAVI Longevity home

Your home should take care of you too.

Most homes are built for how they look. MAVI Longevity residences are built for how they make you feel, sleep, recover, and think. Longevity architecture, lived.

Wake rested. Sleep deeper.

Better nights make better days. When air, light, and rhythm work together, the body finds its natural cadence. You fall asleep faster, wake calmer, and carry that steadiness into the morning.

Let your home recharge you.

Imagine if every shower, breath, and beam of light helped you refuel. Recovery is not what happens after the gym, it is what your home quietly supports every minute you are in it.

Feel grounded as soon as you arrive.

Calm is the new luxury. You sense it before you even notice it. The way a MAVI home absorbs noise, balances temperature, and gives the nervous system permission to relax.

Think clearer. Live lighter.

When the surroundings stop fighting biology, clarity follows. Balanced light and oxygen steady attention; good design becomes the silent productivity instrument.

The mark

Five domains. One organism.

Each dot of the MAVI mark stands for one of the five surfaces every residence is graded against. The body never reads them in isolation, and neither do we.

Ten domains.
One hundred and twenty-nine factors.

Every domain is operationalised. Every factor is measurable. Every recommendation is sourced from peer-reviewed research and translated into actionable architectural specifications.

A different premise

Design,
not discipline.

Most health advice makes you more stressed. Optimise this. Track that. Do not forget to breathe correctly. MAVI takes the opposite approach. We do not add to your to-do list. We build health into the walls.

Your home should

  • Clean the air while you sleep.
  • Regulate your circadian rhythm without an app.
  • Reduce inflammation without a supplement.
  • Calm the nervous system without trying.

AI-native, source-true

Ten elements. One hundred and twenty-nine factors.
One verified specification.

MAVI is built around a longevity-reasoning core. Eight peer-reviewed environmental feeds, four sensor platforms, and your architectural documents flow into a single audited Blueprint. Every claim is sourced. Every recommendation is cited. Every value is traceable back to the dataset and timestamp it came from.
