Cotswold Cottage Extension – Sustainable & Bespoke Home Extension

This cottage extension and remodelling project in Oakridge Lynch, Gloucestershire, creates a spacious and energy-efficient house extension that blends with the traditional Cotswold character. As experienced residential architects in the Cotswolds, we transformed the rear garden footprint, reconfigured the roof, and improved thermal performance to deliver a home that provides comfort, aesthetic harmony, and sustainable living.

Project Brief

The client engaged us to remodel their existing cottage and to design a house extension that would provide additional living areas, more bedrooms, and better connection to the landscape. They needed a design sensitive to local stone vernacular, with improved access and an open, welcoming entrance.

Design Approach & Architectural Solution

The new extension extends the dwelling into the rear garden to form a combined kitchen-diner and living room framing sweeping views over the valley. The entrance was redesigned to offer a warm, functional first impression, with a generous utility and boot room. Internally, the first floor was reconfigured under a new roof structure to accommodate five bedrooms including ensuites. As architects in Gloucestershire and the Cotswolds, our aim was to respect the existing cottage while introducing contemporary living spaces.

Materials, Sustainability & Performance

To enhance energy efficiency, we upgraded insulation throughout, improved the heating system, and selected materials (stone, wood, glazing) in keeping with Cotswold vernacular. The thermal upgrades reduced heating demand, and the design maximises natural light and passive solar gain — delivering sustainable design outcomes without compromising heritage character.

Outcome & Client Experience

The result is a beautifully balanced extension that merges traditional charm with modern comfort: warm, efficient, light-filled interiors; five well-appointed bedrooms; comfortable communal and utility spaces; and improved views and access. This cottage extension in Gloucestershire demonstrates how a sensitive extension can offer both functionality and design excellence.
