Sustainability · Built for the long stay

The most sustainablebuilding is the onethat lasts.

We design for the long stay. Passive comfort first, embodied carbon second, and materials chosen for the next fifty years. The goal is simple — a building that earns its place on the land for longer than the people who built it.

Our approach

Six choices we make before the first wall goes up.

Sustainability is mostly a list of decisions taken early — about orientation, openings, water, energy, and material origin. We resolve as much of it as possible at design stage, when changing our mind is still cheap.

  • 01

    Passive design first

    Orientation, cross-ventilation, deep verandas, shaded openings. We resolve comfort with the building before we resolve it with a machine. Less load. Lower bills. A house that breathes whether the power is on or not.

  • 02

    Materials chosen for fifty years

    We prefer materials with a long second life — stone, lime, hardwood, fired clay — sourced as close to site as the project allows. Specifications are written for ageing, not for the showroom photograph.

  • 03

    Water as a closed loop

    Rainwater harvesting on every project from day one. Greywater recovery for landscape and flush. Permeable hardscape so the ground keeps drinking. We design as if the borewell is a guest, not a tap.

  • 04

    Energy that earns its place

    Solar-ready roofs, EV charging provision, low-W fixtures. Where rooftop generation is viable we build it in at design stage rather than retrofit it later. The grid is a backup, not a default.

  • 05

    Embodied carbon, openly counted

    We track the carbon spent making the building, not just running it. Concrete blends, steel sourcing, transport distance — these are line items in our specs, weighed against the design we want.

  • 06

    Sites that stay alive

    Trees worth keeping are mapped before drawings begin. Native planting goes in early so landscape grows up with the building. The wildlife that was there is meant to still be there at handover.

Where we are headed

Targets, frankly stated.

We are one year old. We do not yet hold the certifications below. Listing them here is a commitment, not a credential — the frameworks already shape how we draw and specify, well before the paperwork catches up.

  • 01IGBCon the pathOn the path to IGBC pre-certification for our flagship residential projects. The framework guides specs even before the plaque arrives.
  • 02LEEDtargetingTargeting LEED-aligned design for upcoming commercial work. Daylight, water, materials and indoor air quality are written into the brief from day one.
  • 03Embodied carbonin motionEvery project we begin from 2025 measures its embodied carbon. The number doesn't excuse the design — it informs it.
  • 04Site biodiversityin motionTree surveys before site clearance on every project. Replanting at a multiple of what is removed, with native species that belong here.

When the certifications arrive we will say so plainly. Until then, the work is the proof.

A commitment

Every project we begin from 2025 measures its embodied carbon.

We will publish what we learn — including the buildings where we missed our own targets. The honest number is the only one worth reporting.
