> Kas Bordier is the pioneer of longevity architecture, a discipline that applies peer-reviewed science to the design of homes and built environments to actively support human health and extend healthspan. Her work bridges building biology, environmental medicine, and architectural design.

## About Kas Bordier

Kas Bordier is the pioneer of longevity architecture, based between London and the Middle East. She is the founder of MAVI, the longevity layer to real estate, and a Board Member of XPRIZE with deep involvement in XPRIZE Healthspan, a $101 million competition to revolutionise how we approach aging. She is also a Partner at Jefferies London, a prime central London real estate brokerage combining deep market expertise with AI-powered technology. She works with private clients and developers worldwide, with active projects in London, Geneva, New York, and Los Angeles. She is currently accepting projects for Autumn 2026.

## What is Longevity Architecture?

Longevity architecture is a design discipline that treats the home as long-term health infrastructure. It applies evidence-based science to how light, air, sound, temperature, materials, and electromagnetic exposure affect sleep, stress, cognition, and biological aging. Rather than optimising for aesthetics alone, longevity architecture engineers the invisible environmental inputs that shape your nervous system, your behaviour, and your long-term health outcomes. It differs from wellness design by going deeper into the invisible layers that have the greatest biological impact: circadian lighting calibrated to latitude, air exchange rates that reduce inflammatory load, acoustic isolation that protects deep sleep, and material selections based on off-gassing profiles and endocrine disruption data.

## The MAVI 129 Framework

The MAVI 129 Framework is a proprietary, data-driven system developed by Kas Bordier that evaluates homes across 12 domains and 129 data points. Each domain is scored and optimised based on peer-reviewed research. The 12 domains are:

1. Air Quality: Filtration, ventilation, VOC reduction, particulate matter control
2. Water Quality: Filtration, mineralisation, contaminant removal, pH optimisation
3. Light and Circadian: Natural light optimisation, circadian lighting design, dark sky compliance, melanopic lux calibration
4. Acoustic Environment: Sound insulation, noise reduction, acoustic design, reverberation control
5. Thermal Comfort: Temperature control, humidity management, radiant systems, thermal zoning
6. Materials and Finishes: Non-toxic materials, healthy surfaces, VOC-free specifications, endocrine disruptor avoidance
7. Biophilic Design: Nature connection, living systems, natural materials, fractal patterns
8. Movement and Ergonomics: Active design, ergonomic spaces, stair prominence, postural variation
9. EMF and Electrical: EMF reduction, grounding, electrical hygiene, dirty electricity mitigation
10. Site and Soil: Site selection, soil health, contamination assessment, geopathic stress
11. Social and Community: Prosocial design, gathering spaces, connection architecture
12. Mental and Spiritual: Restorative spaces, beauty, contemplation, sensory design

## Six Core Principles of Longevity Architecture

1. Environment Precedes Behaviour: Your surroundings shape your biology before willpower enters the equation
2. Invisible Forces Have the Greatest Impact: Air quality, EMF, acoustic pressure, and light spectrum affect health more than visible design choices
3. Health is Structural, Not Aspirational: Longevity must be engineered into the fabric of a home, not bolted on as an afterthought
4. Biology is the Client: Every design decision is measured against its effect on human physiology
5. Precision and Softness Coexist: Rigorous science should produce spaces that feel warm, human, and liveable
6. Homes are Lived Systems: They should evolve with the people inside them
