About | Hashtech Consultancy

We work as a digital partner for architects, engineering consultants, general contractors and developers, turning design information into coordinated models and drawings that can be built.

Our work runs from LOD 100 concept models to LOD 500 as-built models and digital twins, across architecture, structure and MEP. Every model goes through two stages of quality checks before it is handed over.

We also help clients toward more energy-efficient buildings, with models that support lower running costs and less material waste.

A message from our founder

“Every project starts with one question: can the site team build from these drawings?”

I started Hashtech in 2021 to be the BIM partner I would want to hire myself: one that understands how buildings actually go together on site, not just how they look in a model.

We coordinate early, check our work before it leaves our office and stay with you until handover. You deal with me and a small team who know your project inside out.

Thank you for considering Hashtech. I would be glad to hear about your next project.
