Field Diary
Field Diary documents grounded observations from ongoing work with materials, production systems, and livelihoods. It captures what works, what fails, and what changes through day-to-day field engagement, rather than theory or post-hoc interpretation.


Recycled Plastic Fencing: Applications, Benefits and Limitations
Recycled Plastic Fencing Fencing is one of those infrastructure elements that often receives little attention until it needs to be replaced. It is used around farms, parks, gardens, institutions, construction sites, industrial properties and public spaces. In many of these applications, the fence remains outdoors for years and is exposed to rain, sunlight, dust and changing weather conditions. This makes material selection important. Recycled plastic is increasingly being con

Recycled Plastic Bus Shelters: Design, Durability and Applications
Recycled Plastic Bus Shelter A bus shelter has a simple purpose: provide people with a functional space to wait for public transport. But the structure itself has to deal with a difficult environment. It remains outdoors throughout the year and is exposed to sunlight, rain, dust, pollution and continuous public use. For municipalities and other public agencies, the challenge is therefore not simply to construct a shelter. It is to create an infrastructure asset that is practi

Recycled Plastic Infrastructure: A Practical Alternative to Conventional Materials
Plastic waste is usually discussed as a disposal problem. Once plastic has been collected, the conversation often ends with recycling, processing or waste management. But recycling is only one part of the equation. The more important question is what can be made from the recovered material and whether those products can perform a useful function for several years. This is where recycled plastic infrastructure becomes relevant. Instead of treating discarded plastic only as was

Bamboo Structural Load Systems in Built Practice
A full-scale bamboo structure was constructed to test load-bearing behavior under real construction conditions. The system supported over 1.25 tonnes without failure, revealing that joint precision, wind-induced movement, and labour intensity become critical factors as height and structural complexity increase.

Textile Waste for Circular Furniture Design
Discarded sarees were combined with cane frames to explore circular furniture systems using bio-materials and textile waste. The project examined how waste textiles could act as structural elements rather than decoration, revealing both the potential and limits of small-scale, low-energy furniture production under real material variability.

Hurdles of Scaling Bamboo Housing in India
This document captures two decades of practice working with bamboo housing across India. Rather than presenting bamboo as a scalable alternative, it documents why scaling repeatedly fails in real conditions. The constraints were not limited to material strength or design imagination, but to sourcing, treatment, logistics, labour skills, regulatory ambiguity, pricing, and market perception. Bamboo housing did not fail; the systems around it were never designed to support it.
