It is of straw bale construction and designed across two single-storey buildings in keeping with its diminutive neighbours. Best of all are the rather nice Rationel AURA windows – in some unexpected sizes and formats 🪟🏡

This gem of a brick-and-flint home in Saffron Walden, Essex began life as a two-up, two-down. Thanks to a small but ingenious extension project, it now has ensuite bathrooms upstairs and an enlarged and rejigged downstairs layout. Proud as punch to say, though, that it’s the Rationel FORMAPLUS windows with standout glazing bars that the visitors can’t stop talking about 🪟🏡
