Eight associates collaborated with Amin Taha’s architecture studio Groupwork and the structural engineer Webb Yates in the design of a conceptual 30-storey stone office block that would be cheaper and more sustainable than concrete or steel equivalents.
The research found that large commercial buildings could be built more cheaply and with less of an environmental impact using stone rather than concrete or steel. By specifying quarried stone to be used within the building, the embodied carbon would be solely caused through the extraction, transportation, and installation of the stone. Additional processes such as polishing, etc, would also result in a higher embodied carbon. A building constructed primarily from quarried stone would result in a carbon reduction when compared to a concrete frame (approx. 60% reduction) or steel frame (approx. 80% reduction).
Furthermore, the analysis showed the specification of cross-laminated timber (CLT) could result in a much more favourable embodied carbon, due to the nature of timber sequestering carbon throughout its lifetime as a tree. The specification of CLT floors in place of stone floors would offset the embodied carbon of the entire stone structure (stone exoskeleton, core walls, and floors).
The stone skyscraper research project forms part of an exhibition called New Stone Age at the Building Centre in London.

"Eight Associates has worked for Cadogan for many years to help us reach our objective to develop more sustainable buildings on the Estate. We have found their assistance in helping us to achieve this objective invaluable and Eight Associates form an integral part of the develop team in reaching this goal."
Nicholas Dutton Head of Building Surveying, The Cadogan Estate
"Eight Associates is a lovely company to deal with and I recommend with enthusiasm anyone who would consider them. They are diligent and professional, usually actioning before their deadlines – great team players."
Steve Reynolds Director, Thornton Reynolds Engineering Consultancy
"We have utilised the services of Eight Associates several times now and found them to be professional, approachable and friendly. They understand the requirements and demands of BREEAM assessments and have helped us early on at design stage to ensure that our construction projects achieve the required rating. A key part of compiling the evidence is a prompt and efficient review which they deliver consistently. I look forward to working with Eight Associates again in the future."
