This week’s sketch is by Lesley Hally at LA Hally Architect

This week’s #buildingdoodle sketch is by Lesley Hally, principal architect at LA Hally Architect. She says: “This design was put together for our office Christmas card - it was based on an initial sketch for a client, who was looking to add a contemporary two-storey extension to their 1940s bungalow. The final project ended up looking a little different, but we still love this image and its festive arrangement!”
