01 / Overview

Trusted with firsts.

L+W was proud to be part of the Design & Build team behind the interior fit-out of Malaysia's first-ever Apple flagship store, at The Exchange TRX in Kuala Lumpur.

The store drops from a glass pavilion on TRX City Park through three levels, around a central forum under a stepped, back-lit ceiling. Behind those calm surfaces sits a dense frame of new steel that L+W designed to hang from, and bear onto, the mall's existing concrete structure.

It followed straight on from our work on the first Tesla 3S Centre in Cyberjaya. Two firsts, back to back, delivered by a team where senior engineers stay hands-on from concept to completion.

02 / The challenge

A sculptural interior, built inside a finished mall

Every structural element had to disappear. The ceiling ribs, forum wall and feature stair are read as continuous, seamless surfaces, so the steel behind them had to be stiff enough that panels stayed true to a few millimetres under load, temperature and footfall.

All of it had to land on an existing building. New loads were taken back to the mall's columns and transfer beams without strengthening works that would disturb the floors above and below, while the rest of The Exchange TRX stayed open.

    Long-span transfer truss over the forum wall

    A storey-deep steel truss spans the full width of the forum, carrying the stone-clad wall and the gallery edge above a column-free opening. It was set out to the stone joint pattern so the truss nodes sit behind panel joints.

    Suspended framework for the stepped ceiling

    Galvanised hanger frames and diagonal bracing hang the ceiling ribs from the slab above, with adjustable connections so every tier could be trued to the architect's curves before the panels went on.

    Feature stair

    The stair's folded-plate stringers were designed for a lively but comfortable feel underfoot, then propped and checked in place before the sculpted white finish was applied.
