FlexEhouse

FlexEhouse
Bespoke Electrical Buildings
Formerly QSK E-House / Modular E-House
Purpose-built

Bespoke Electrical Buildings for:

  • MV / HV switchgear
  • Power and distribution transformers
  • Control, protection and SCADA systems
  • Auxiliary and LV distribution equipment
  • Complex multi-equipment layouts

DeliversA fully engineered building shaped around the equipment package.

FlexEhouse is a bespoke, factory-built electrical building. Every unit is engineered around its equipment package — switchgear, transformers, control systems — so the building protects the assets without dictating layout. Delivered complete to site, ready for connection.

Exclusions

Out of scope — owned by other trades.

  • Power cabling termination — NEVER our scope
  • Switchgear, transformers, control panels, or any electrical equipment housed inside
  • Electrical design, wiring, or termination of housed equipment
  • Civil works — foundations, groundworks, drainage beyond the footprint
  • Grid connection or regulatory approvals

WE NEVER TERMINATE POWER CABLING — THAT STAYS WITH THE ELECTRICAL CONTRACTOR / INTEGRATOR.
