What Hemspan does
Hemspan is a UK-based bio-based construction technology company headquartered in Cambridge (registered as a private limited company in England & Wales), founded in 2020, that designs, manufactures, and delivers the BIOHAUS® panellised closed-panel building system for low-carbon homes and public buildings. The BIOHAUS platform is manufactured offsite using UK-grown industrial hemp combined with structural timber, and is positioned as the only BOPAS-accredited panellised bio-based building system in the UK. The technical basis combines a proprietary BIOHAUS closed-panel system with HEMSPAN BIO BOARD (a breathable hemp straw and mineral-binder interior board), HEMSPAN BIO BLOCK (hemp shiv, dolomitic lime and probiotic insulation blocks), and distribution of IndiTherm, the first BBA-certified industrial hemp insulation.
Hemspan operates a hybrid revenue model across hardware sales, professional services, and licensing. Project-based BIOHAUS design, manufacture, and construction management services are sold directly to enterprise customers — including developers, housing associations, local authorities, and landowners — through flagship partnerships with EARTHSTONE HOMES (28 homes at High Bar Lane, West Sussex), the Duchy of Cornwall (West Swainsford Farm proof-of-concept), and ADAM Architecture (masterplanner for the ~2,000-home Rochford Park flagship development in Essex). A separate e-commerce storefront (hemspan.com/shop) sells BIO BOARD (£25.00/sqm), BIO BLOCK, and IndiTherm insulation batts (£6.84–£13.68/sqm) globally to self-builders and trade buyers, with custom BIOHAUS panels carrying 8–16 week lead times. Go-to-market blends direct enterprise field sales with channel partnerships (engineering, manufacturing, and distribution partners including FIBAMAX, IndiNature, and Margent Form), supplemented by content marketing, industry events (Groundswell), CPD presentations, and earned media.
The company's strategic positioning targets the embodied-carbon problem in construction (cited at ~40% of global carbon emissions) and the UK's poorly-insulated housing stock. Performance credentials include ~0.100 W/m²K U-values (Passive House level), approximately 1 tonne CO₂ stored per square metre versus conventional construction, BOPAS accreditation for the BIOHAUS system, BBA certification for IndiTherm, and Highly Commended recognition at the UK Green Business Awards 2026. Forward capacity is anchored by a planned dedicated BIOHAUS factory with a stated production capacity of 2,000 homes per year and 350+ projected jobs. Current reported headcount is 1–10 employees, no external funding rounds are disclosed, and the company operates as a private limited company with no parent entity.

Company assessmentEmerging players
- HempFlax: European hemp cultivation and processing company supplying raw hemp fibre, shiv and mats for construction, insulation and other industries. Comparable on the upstream hemp-for-construction supply chain that Hemspan taps via FIBAMAX.
- Hempitecture: US-based hemp building materials company producing hempcrete, hemp batts and hemp-based panels. Comparable product portfolio (hemp insulation, hemp board, hemp blocks) to Hemspan, focused on North American rather than UK market.
Broad incumbents
- Wernick Buildings (offsite modular): Established UK offsite/modular building manufacturer producing timber-framed and steel-framed modular housing for developers and housing associations. Comparable on BOPAS-accredited offsite panellised/modular delivery for UK housing developers, though operating in conventional materials at much larger scale.
