Standing next to Little Nest (Sarang Kecil), a prototype rural haze shelter to be built in village housing. Designed by Wally Tham to be built with locally sourced rattan and bamboo.

Located in Palangka Raya, NestHQ (Sarang) : The first Haze shelter in Indonesia with 2 stages of active air filtration, capable of reducing PM2.5 particles by 95–99%.

A converted shop space of 2000 sq feet, it’s up and running with capacity for 40 adults or 60 children.

Two years in the making and after extensive R&D, we have Indonesia’s first haze shelter. Based on my experience in extreme PM2.5 conditions, we have built airflow restricted entry ways, 1st stage filtration to draw 70–90% filtered oxygenated air in & have 6 Airazor purifiers to handle the the remaining fine particles.

Little Nest(Sarang Kecil): Our advanced haze shelter prototype for rural village (wooden-board type) housing.

By weight, Little Nest’s structure is made from 99% sustainable materials: readily available rattan or bamboo. It was designed to be simple for any village resident to build. We made the shell from IKEA shower curtains, sealing out pollution.

Within a week of our sketch, we have the first prototype for Little Nest, our design addresses the challenges of sealing village houses that were built for ventilation in mind. These houses have numerous gaps to promote airflow, great for heat management but potentially deadly during peatland fires as airflow brings with it gases and pollutants.

Pollution levels during my 6 day visit ranged from 35,000 PM 2.5/cubic feet to 1.7 million PM 2.5/cubic feet on any given day.
