CplusC Architectural Workshop

What CplusC Architectural Workshop does

CplusC Architectural Workshop, trading as CplusC Architects + Builders, is a Sydney-based integrated design-build firm founded in 2004 by architect-builder Clinton Cole. The company operates an unusual architect-builder model that delivers both architectural design and licensed construction services under a single team, removing the traditional tender and hand-off steps between separate design and construction firms. The firm serves mid-market residential homeowners across New South Wales with a portfolio that includes new builds, alterations and additions, heritage conservation, bushfire-zone (BAL FZ) residences, and inner-city extensions. Its service offerings span architecture, construction, heritage architecture and alterations, sustainable architecture, regenerative design, landscape architecture, feasibility studies, bushfire compliance, and interior architecture.

The firm's technological and design differentiation lies in regenerative and sustainable architecture. Project specifications incorporate passive heating and cooling (thermal mass slabs, cross-ventilation via operable windows and louvres), solar power with battery storage, heat pumps, rainwater and blackwater systems, recycled and timber materials, and in select projects (Welcome to the Jungle House, Holocene House) integrated aquaponics producing edible fish and vegetables, beehives, edible gardens, and off-grid capability. Holocene House is the first Australian residence certified by the International Active House Alliance and operates as a carbon-positive dwelling. CplusC holds specific expertise in high Bushfire Attack Level (BAL FZ) compliance through elevated structures, fire-resistant materials, and concealed bushfire shutters.

The commercial model is direct-to-consumer and project-based. Pricing is quote-based per commission with two integrated revenue streams: architectural services (concept through construction documentation) and construction services as a licensed builder. Customer acquisition relies on portfolio visibility, referrals, and earned media in publications including Sydney Morning Herald, Dwell Magazine, Architecture & Design, VISI, Gestalten, The Design Files, Habitus, and Green Magazine. The firm became the first Australian architect-builder to achieve Certified B Corporation status in 2022 and has accumulated over 100 industry awards from 2005 to 2025. Headcount sits at approximately 15 team members combining architects, builders, project managers, site foremen, office staff, and apprentices, including trade apprentices developed internally in partnership with UNSW through a recurring scholarship program.
