Five Renovations Divide Without Walls: A Third Way Between Cellular and Open Plan

architecture-design · 2026-08-26

A recent survey examining five apartment renovations in Europe and Asia indicates a novel approach that blends cellular and open layouts through the use of objects for division. In Madrid, Extrarradio Estudio revamped TET House, resulting in a seamless 68-square-meter area bordered by a green zigzag design. Georgios Apostolopoulos Architects in Athens redesigned an 80-square-meter apartment by eliminating walls and incorporating movable joinery for separation. Prague's No-Wall Apartment by RDTH architekti showcases a central block complemented by translucent partitions and curtains. ASAP-ZT Pitro Sammer's Chromatic Chambers in Vienna transformed six rooms into a circular configuration. In Singapore, No Sense Studio's Nos. 9 utilizes raw materials to showcase the owner's collection. These innovative dividers tend to be more expensive than standard partitions and pose maintenance difficulties.
