AR Design Studio have designed a single storey extension to a semi-detached house in North London, UK. The team at AR are particularly interested in relationships between inside and outside space, between the man-made and nature. Hidden from view, behind the ordinary looking façade of a modestly sized semi-detached house in North London, sits an elegant piece of modern contemporary architecture. The recently retired owners sought to adapt the existing small and cramped property into their perfect home. Despite their North London site, they were eager to work again with the south coast based architects, having experienced an enjoyable and smooth design process on an earlier holiday home. AR Design relished the opportunity to reunite with an old client. The brief was to design a single storey extension at the rear of the existing 3 bedroom property, linking in with the original, whilst making minimal physical changes. The open-plan extension was to comprise of a new kitchen, new dining/living space, utility room, cinema room, WC and office area; with the aim to bring views of the garden and more light into the property.
