Commercial Office Conversion

Conversion of a former main office building into productive additional space intended to create a new revenue stream for the property.

The challenge

The building had stopped earning its footprint. The task was to convert it into space that generates revenue, without disrupting the wider operation of the site during the works.

The approach

The conversion was planned around the commercial objective first — what the space needed to earn — with the construction scope, programme and specification shaped to serve that outcome.

Key considerations

  • Keeping the wider site operational during the works
  • Matching specification to the intended commercial use
  • Controlling cost against the projected return on the space

Shown for a conversion of around 150 m²; the existing building's condition is the biggest single variable, which is why conversion estimates carry a wider risk allowance.
