Development house is a proposal for a nine-storey mass timber office block in Shoreditch. ? The floor slabs were proposed as a CLT and concrete hybrid, glulam columns and beams for the frame structure. ? The building consists of five vertical segments around a central core, stepping levels between each slice create an opportunity for daylight, ventilation and views whilst allowing for the most efficient structural timber design. An outdoor garden terrace at the top of each section is proposed to encourage well-being.
