Bespoke Energy-Efficient Homes in Cornwall & Devon

At Metters & Wellby, we are award-winning architects in Cornwall specialising in the design of bespoke, energy-efficient homes across Cornwall and Devon. We work with private clients and small developers to create beautiful, sustainable new build houses that respond to each unique site and lifestyle.

Whether you're building a one-off home in the countryside or a small development by the coast, we offer the full architectural service—from first concept through planning, technical design, and energy compliance.

Project Feasibility Appraisal

Early-stage advice to assess viability, constraints, and development potential

Concept and Design

Interior Design

From coastal plots to countryside settings and barn conversions, we specialise in crafting homes that make the most of their surroundings—using natural materials, timeless design, and a fabric-first approach to energy efficiency.

Energy Efficient Contemporary Coastal Living

Set on the dramatic North Cornwall coast, Avalen is a bold and beautifully detailed new home that draws inspiration from its rugged surroundings. Clad in black-stained timber with a metal roof, the design embraces a contemporary coastal aesthetic while framing panoramic sea views. Inside, clean lines and natural textures create a warm, minimalist retreat. Behind the striking appearance lies a highly insulated and airtight build, offering strong energy performance without compromising style or setting.
