CplusC Architects + Builders

Overview

CplusC Architects + Builders is an award-winning Sydney practice that combines architecture and construction to deliver bespoke, sustainable homes across New South Wales and broader Australia. Founded in 2005, the firm operates as an integrated architect-builder studio, managing projects from initial concept through to keys – avoiding the usual hand-offs between design and construction.

What they do

CplusC specialises in site-specific residential architecture and custom home building, with a strong emphasis on regenerative and energy-aware design. Their offering typically includes:

• Full architectural design and documentation

• In-house building and project management (turnkey delivery)

• Sustainability and passive-house style strategies (energy, water, material reuse)

• Bespoke interior and landscape coordination

Their project portfolio spans high-end renovations, new houses and demonstrator sustainability projects.

Core values and credentials

CplusC positions sustainability and social responsibility at the centre of its practice. They are a certified B Corporation – a formal recognition of social and environmental performance having achieved B Corp status in 2021. This accreditation underlines the firm’s commitment to measurable sustainability outcomes as part of everyday practice.

The firm publishes detailed project case studies (including award-winning and research-led builds) and reports a multidisciplinary team of architects, builders and project managers working from their Surry Hills studio. Their contact and company identifiers (ABN and builder/architect licences) are publicly listed on their site.

Notable work & innovations

CplusC has developed highly visible research and demonstration projects that push sustainable residential design. For example, the Holocene House project is widely cited for its ambitious aim to be energy and water self-sufficient and is described as Australia’s first Active House type project. The studio’s work features regularly on architecture platforms and in specialist publications.

Who are their ideal customers?

CplusC’s typical or “ideal” clients are:

• Homeowners seeking a high-quality, bespoke residential project (new build or major renovation) who value design excellence and lasting craftsmanship.

• Clients with an appetite for sustainability: those who want regenerative, energy-efficient homes, water resilience and materials transparency.

• Owners looking for a single team to manage design and construction (clients who prefer turnkey, managed delivery rather than coordinating separate architect and builder teams).

• Clients prepared to invest in long-life, low-running-cost homes where upfront design and material decisions prioritise lifecycle performance over lowest initial price.

These clients are usually premium-market private homeowners (families, professionals, downsizers, or clients building a legacy home) who prize collaboration, accountability and environmental outcomes.

Why choose CplusC?

• Integrated delivery – design and build under one roof reduces friction and risk during construction.

• Sustainability leadership – B Corp status and demonstrator projects show a practical commitment to environmental and social measures.

• Craft and detail – the team combines architectural design with builder craft knowledge to deliver considered materials, joinery and site responses.
