What Solarpunk Futures does

Solarpunk Futures is a Goa-based sustainable construction company founded in 2022 that designs and builds cement-free custom homes using locally sourced and waste-derived materials. Its core technology stack centers on Compressed Stabilised Earth Blocks (CSEB) made from excavated lateritic soil combined with sawdust waste, laid in an adapted Flemish bond pattern that enables load-bearing walls without cement or steel, supplemented by lime-based mortars, limecrete flooring with wood shaving fillers, granite waste-based decorative plaster, integrated solar roofing with stone-coated tiles, closed-loop greywater recycling (STP), and natural pool systems. The company is also exploring Ultra High Performance Concrete (UHPC) elements (160 MPa compressive strength) for ecologically sensitive structural applications.

The company's portfolio currently comprises three projects: Aadi Villa, its first demonstration home under construction in Nachinola, North Goa (1,200 sq mt site, 958 sq mt built-up); the Loutolim multi-home community project in South Goa with Roy and Upasana's home as the pilot unit; and a prototype project at Sangolda for Serie Architects' new office that is being used to test a ₹2,500/sq.ft sustainable construction cost benchmark. All materials are sourced within a 500km radius of project sites to reduce transport emissions and support local supply chains.

Solarpunk Futures generates revenue primarily through project-based fees for custom sustainable home design, engineering, construction management, and on-site execution, with secondary potential income from material R&D collaborations and consulting services on cement-free construction methods. The company operates a direct-to-consumer, community-led, and event-driven go-to-market approach — engaging prospects through website content, on-site visits, and word-of-mouth within the Goa community — and executes projects through in-house architects and site supervisors coordinated with strategic partners including Serie Architects (design), StrucArt (structural engineering), Greenjams (Agrocrete bricks), Strawcture (agricultural waste boards), God's Granites (waste stream supply), and SDPL Pvt. Ltd (UHPC). The core customer segment is mid-market individual homeowners and families in Goa seeking environmentally conscious residential construction, with early adjacent work for an architecture firm (Serie Architects).

Partnerships

Five partnerships are on record, tiered minor and core.

• StrawctureminorStrategic or Co-development Partner · 1 July 2025Strawcture works with agricultural waste-based boards and lime-based finishes in partnership with Ricehouse (an Italian company). Solarpunk Futures met with Strawcture to evaluate samples for interior wall paneling and light roofing applications. Initial material trials were initiated in July 2025, with further testing scheduled. The partnership supports SPF's goal of using low-carbon, waste-based construction materials.
• GreenjamscoreStrategic or Co-development Partner · 1 July 2024Greenjams, founded by Tarun Jami, creates eco-friendly construction products using crop leftovers and industrial waste. Solarpunk Futures collaborates with Greenjams to adapt their Agrocrete® bricks (made using BINDR binder, agricultural waste, and industrial fillers) for projects in Goa, using local waste materials including furniture factory waste and excavated soil. Over the past year, the companies have been developing and testing bricks for various construction purposes including load-bearing walls and partitions. Greenjams' Agrocrete® is carbon negative, offering better thermal regulation than traditional concrete.
• God's GranitesminorStrategic or Co-development PartnerGod's Granites was particularly eager to work with Solarpunk Futures on repurposing their granite waste. The company generates approximately 1600 tonnes of slab offcuts every month when cutting smooth blocks out of raw stone blocks. SPF's multidisciplinary team (material scientist, architect, interior designer) conducted a comprehensive evaluation of the material to explore applications including terrazzo flooring, landscaping elements, cladding, and decorative composites. Initial experiments transformed granite offcuts into decorative plaster.
• Serie ArchitectscoreImplementation/ SI/ Consulting PartnerSerie Architects serves as the primary architectural design partner for Solarpunk Futures projects. They are responsible for design coordination, structural drawings, TCP submissions, Blueprint drawings, and BOQ development. Serie is also the client for the Sangolda office prototype project testing the ₹2,500/sq.ft sustainable construction benchmark. The firms work closely on adapting designs to SPF's cement-free construction methodology.
• StrucArt (Bhairav Patel)coreImplementation/ SI/ Consulting PartnerBhairav Patel of StrucArt serves as the structural engineer for Solarpunk Futures projects. He collaborated on finalizing the structural design for Roy and Upasana's home at Loutolim, working with Serie Architects and SPF.

Represents the broad incumbent competitive threat, as Tata has scale advantages and could easily enter the premium sustainable home segment where SPF operates.
• Habitat for Humanity India: Global nonprofit delivering affordable, increasingly sustainable housing in India through volunteer builds and partnerships. Competes for the same affordable sustainable homeowner segment as SPF, but with vastly greater institutional capacity, donor funding, and geographic reach.

Direct peers

• Auroville Earth Institute: Pioneering Indian organization specializing in earth architecture, CSEB technology, and compressed earth block production. Shares SPF's cement-free, earth-block-based construction methodology and tropical-climate expertise, serving as both inspiration and direct method competitor in India's sustainable building space.
• Strawcture: India-based startup producing agricultural waste-based boards and lime-based finishes in partnership with Italy's Ricehouse. Strategic partner of SPF for interior wall paneling and light roofing applications, with directly comparable waste-stream-to-construction-material value proposition.
• Greenjams: Indian eco-friendly construction products company founded by Tarun Jami, producing Agrocrete bricks from agricultural and industrial waste using BINDR binder. Active co-development partner with SPF, with overlapping low-carbon masonry product portfolios serving the same Indian sustainable construction market.

Others

• CarbonCure Technologies: Canadian carbon-utilization technology that reduces embodied CO2 in concrete. Operates in adjacent sustainable construction infrastructure space; complementary to SPF's cement-free mission by improving rather than eliminating concrete, representing a competing technological pathway to low-carbon building.
