    Residential Architects in Cornwall

    We work across Cornwall on private residential projects of varying scale and complexity, including Truro, Falmouth, Newquay, Wadebridge and across North and West Cornwall. Every project begins with a deep understanding of your brief, your site and your budget, followed by clear, structured guidance through each stage of the process. You can explore our completed homes across Cornwall to see how we approach design across different settings and contexts.

    • New build homes – bespoke contemporary and traditional designs, tailored to your site
    • Self build architecture – support from feasibility to completion, with a practical, staged approach
    • Extensions and renovations – improving space, light and performance without losing character
    • Coastal and rural properties – designs that respond to exposure, views, access and local materials

    Sustainable & Low Carbon Architecture

    As sustainable architects in Cornwall, we design with performance at the forefront – reducing energy demand, improving comfort and creating homes that are future-proofed against rising energy costs and changing building standards.

    Our approach considers the full fabric of the building: insulation, airtightness, thermal bridging, glazing strategy, ventilation and material selection – ensuring your home performs as intended, not just on paper.

    • Low energy design using passive principles and efficient building fabric
    • Material choices that balance aesthetics, durability and environmental impact
    • Overheating risk management (particularly important for south-facing coastal sites)
    • Healthy indoor environments through ventilation and moisture-aware detailing

    Passive House Design in Cornwall

    If you’re aiming for the highest level of building performance, ARCO2 also provides Passive House design support. Passive House is a proven standard for delivering exceptionally comfortable buildings with very low heating demand, achieved through rigorous design and detailing.

    We can advise on whether Passive House is right for your project, and support you through the key decisions that make the difference – from orientation and form factor to glazing ratios and ventilation strategy.

    Planning Permission & Building Regulations

We support clients through planning permission and Building Regulations with clear drawings, thoughtful design justification and a calm, organised approach.

    • Feasibility and planning strategy to reduce risk early
    • Pre-application support where appropriate
    • Planning submissions with robust drawings and design rationale
    • Technical design and Building Regs information for construction
