With 6 Directors, 70+ experienced engineering specialists in offices in Glasgow, Manchester, Harrogate and London, DSSR continues to be one of the most innovative, privately-owned consultancies in the UK.

A forward-thinking firm, sustainability is a central feature within every design project; DSSR is committed to reducing carbon emissions and energy consumption through each commission to which it contributes.

DSSR benefits from dedicated teams which specialise in specific market sectors, including retail, leisure, education, commercial, residential, healthcare and industrial; we can draw on these specialist teams to deliver robust, innovative and sustainable M&E design solutions to our clients.

Collaborative working is at the core of DSSR’s ethos and we strive to form integrated project teams, working closely with clients and other professionals to ensure the brief is met and projects are successfully delivered.

In response to the wider range of procurement strategies in the construction industry, DSSR has for many years been appointed directly by main contractors and building services contractors to undertake the design. As a result, we have a diverse portfolio of projects which reflects our impressive range of capability and expertise.
