BUILT FROM THE GROUND UP
A decade of precision metalwork, engineered for Singapore's most demanding residential and commercial projects.
Hepta Designs was founded in 2014 by a team of structural engineers and fabricators who believed Singapore deserved better than off-the-shelf metalwork. We set up our workshop in Tuas and started with a single CNC plasma cutter and a commitment to zero-compromise quality.
Ten years on, we've completed over 48 projects across HDB flats, condominiums, landed properties, and commercial spaces. Every piece that leaves our workshop is measured, welded, and finished by hand — no outsourcing, no shortcuts.
