The internal layout however was modified where necessary, with present needs of diverse trade mix taken into consideration. A new M&E system with built-in flexibility was carefully planned and installed to serve the needs of providing for a variety of potential tenants. The system also included extensive water features and a custom-built lift.

The entire basement of the original building was remodelled to provide back-of-the-house service to both the original building and the new annex. It included a switch room, a dumbwaiter, kitchen provision, and store.

The new annex was built with the most advanced glass insulation technologies that have supporting structures behind the glass, and tension cable holding some parts together. Glass and metal were selected for this new structure to balance the historical “weight” of the masonry building with the lightness and delicateness that these “new age” materials are associated with.

The surrounding environment of the Waterboat House has also been transformed and enhanced. The aged space of the Merlion Pier and its surrounding is laid with a timber-covered deck, creating a pleasant and popular outdoor space for leisure and entertainment. The preservation of heritage trees, such as the large Jejawi or Malayan Banyan tree that overlooks the Singapore river and the tall stately Assam or Tamarind tree beside the Anderson Bridge, retains a hold to the past and adds serenity to the now very popular space for interactions and activities.

The maximum Retention, sensitive Restoration and careful Repair - the three 'R's - in the restoration of the Waterboat House, the creative adaptive reinterpretation of the interior spaces for modern usage and commercial viability, together with the transformation of its surrounding environment into a beautiful and usable outdoor space have brought a new vibrancy and vitality to this part of the river.
