The buildings at Willowa, Leśna and Obrońców Westerplatte streets marked the first stage of a large-scale competition for the urban development of the southern part of the city announced in 1910. The picturesque and comfortable villas built in that area alluded to English solutions promoted by H. Muthesius, who was a member of the competition jury. Most of them are quite spectacular, with various architectural shapes, often diversified by the use of numerous bay windows, roof windows, loggias, galleries and balconies. The houses feature mainly multi-sloped or pediment roofs with large, often broken-line surfaces. Façcades are devoid of historical ornaments but decorated with numerous muntin windows and shutters in a variety of forms. Gables are often faced with timber framing or a planked masonry wall.
