3D PERSPECTIVE · TWO GLASS-WALLED MEZZANINES
SBI · DESIGN · BUILD · CONSTRUCT
Commercial Office Fitout · Sydney
A proposal for Precision IT
Prepared for Gerard Buscombe · Unit 2, 41 Accolade Ave, Morisset NSW
Walks Gerard through the proposal, names the two mezzanines, and points to the Confirm Site Measure button.
Two distinct mezzanines, one coordinated build. Upstairs becomes a focused office volume — clear-glazed perimeter, full-light feel, acoustic separation from the operations floor. Downstairs becomes a credibility piece for Precision IT: a glass-walled boardroom that reads as serious from the moment a client walks in.
Delivered as a single program by an SBI Project Manager — partitioning, glazing, ceiling, electrical, HVAC, flooring and painting all sequenced under one schedule. You see one face, sign one variation register, and take one handover.
Glass partitions are the #1 acoustic failure point in mezzanine offices. Most builders spec 10mm float glass with brush-strip seals — looks identical to a premium spec, but every conversation in the boardroom carries to the workstations downstairs. SBI specs acoustic-rated laminated glazing with full-perimeter intumescent seals (head, jamb, threshold) — delivering Rw35-38 in glass and Rw45 in the solid framed walls behind it. The difference between a boardroom that feels confidential and one that doesn't is roughly $40 a linear metre, made invisible at handover.
