We designed this single-storey side extension for a beautiful detached Cotswold stone cottage with far-reaching views of the Cotswold countryside. Our design has created a new sunroom with effective use of glazing and roof lights to flood the interior space with natural light, whilst also allowing for stunning views of the surrounding gardens. Aluminium frame bi-fold doors in anthracite grey give a contemporary twist to the traditional elements of the oak framework, timber larch cladding which will weather naturally silver and Cotswold stonework to match the original building.
