Environmental responsibility
We reject sustainability as an empty marketing buzzword. In Nepal’s demanding geography, sustainable architecture is grounded in building thermodynamics, local material intelligence, and structural longevity.
Tangible practice framework
Proven passive strategies that reduce mechanical energy dependence and operational costs throughout a building's lifecycle.
Designing window apertures and exterior eaves specifically calibrated for seasonal solar angles. In mid-latitude valleys like Kathmandu, low winter sunlight is invited deep into interior rooms for natural thermal heating, while high summer midday rays are blocked by overhangs.
Utilizing central vertical courtyards, stair atriums, and clerestory louvers to induce the convective chimney effect. Hot, stagnant air rises and vents out the upper roof, pulling cooler outdoor breezes through ground-level habitable spaces.
Deploying locally manufactured clay bricks, exposed stone masonry, and cavity walls to act as thermal batteries. In areas with high diurnal temperature swings, heavy masonry walls absorb daytime heat and radiate warmth indoors during cool nights.
Integrating permeable paving, bioswales, and on-site rainwater harvesting attenuation tanks. Instead of overloading municipal drains during intense monsoon downpours, water is filtered and recharged into local subterranean aquifers.
Prioritizing timber from certified regional sources, indigenous stone quarries, and local steel mills to drastically minimize transportation emissions while celebrating the authentic textural character of Nepalese craftsmanship.
The most sustainable building is the one that survives for generations without needing demolition. By designing structural frames with ductile seismic detailing and flexible interior partitions, our buildings adapt as user needs change over decades.
Two climates, two responses
In cities like Bhairahawa, Nepalgunj, and Dhangadhi, extreme summer temperatures exceed 42°C accompanied by high humidity. Our architectural strategy prioritizes deep wrap-around verandas, ventilated roof cavities, solar-reflective coatings, and central courtyard water bodies that facilitate evaporative cooling breezes.
In Nepal’s mid-hills, architecture must balance cold winter nights with pleasant temperate summers. Here, our focus shifts to southward volumetric orientation, high-performance double-glazed fenestrations that capture winter solar gain, and cross-ventilation openings that eliminate the need for mechanical cooling during summer months.
