Proposal for Miriam Macdonald
39 Thames Quay, London
Dear Miriam,
Your renovation at 39 Thames Quay is a rare opportunity to address the conditions that have affected your health at the source, before the walls close.
We apply the full MAVI 129 framework to your project: 129 health indicators across 10 core pillars. Every pillar is assessed. We then translate the findings into buildable specifications with implementation guidance that your contractor and design team can work from directly.
We have structured two levels of involvement so that you can choose the depth that feels right for you. Both apply the full framework. The difference is how many pillars receive a deep dive and how closely we stay involved as the design evolves.
The decisions made during the next three months will be locked into the building fabric for 15 to 20 years. Retrofitting ventilation, rewiring for low-EMF, or changing materials after the walls close costs five to ten times more than getting it right now. This is the window.
Essential
25,000 GBP + VAT
Deep dive on the three pillars that matter most given your current situation: air, water, and light. Baseline scan across the remaining seven. Your team receives a structured specification with clear targets and implementation guidance.
When implemented faithfully by an experienced contractor, this level of specification is often sufficient to deliver a materially healthier outcome.
Aligned to your 3-month renovation programme. Payments: 60% to secure your place, 40% on completion.
Evolve
55,000 GBP + VAT
Deep dive on six pillars: air, water, light, acoustics, materials, and sleep. Bespoke criteria tailored to your scheme. Design comments on your plans at two stages. Monthly check-ins throughout.
In Evolve, MAVI remains actively involved as the design evolves, ensuring that health-critical specifications are not diluted during coordination, value engineering, or procurement discussions.
Aligned to your 3-month renovation programme. Payments: 60% to secure your place, 40% on completion.
For clients who want nothing left to chance, Signature provides full-depth analysis across all ten pillars, a dedicated MAVI resource throughout, and a verified home at completion. 85,000 GBP + VAT. Ask us for the details.
