a phase 2c t The Urban Redevelopment Authority, which spearheaded the future phase 2b surface pilot project, had wanted to revitalize the Tanjong Pagar area carpark duxton road The shophouses before restoration th of Chinatown - an area rich in 19 Century urban heritage that had deteriorated gradually over the years. No. 9 Neil Road The aim of the pilot restoration project was also to educate the public and industry on the importance of heritage conservation by revealing the buildings’ long hidden beauty, so that the planned gazette of our first conservation areas would receive public buy-in.

A rather unusual clause was inserted into the restoration contract, which was awarded in May 1987. One unit had to be restored first before the contractor can start work on the rest of the 31 buildings.

The unit to be restored was to be the sample unit that would set the standard for the other shophouses in Tanjong Pagar and the rest of Singapore. Work had to be monitored closely; the finishing material tested and confirmed, the working procedures efficient, all problems resolved effectively and the standard of workmanship upheld for this unit.

No 9 Neil Rd was chosen as this sample unit. The building was selected for its rich external facade decorations and the fact that the timber fascia beam in front, a very important structural element, was very badly deteriorated and needed to be replaced. The Authority saw this was a golden opportunity to work out the construction method to be used for some of the remaining shophouses that had similar problems.

The two-storey building with an attic floor was in poor condition. A large part of the roof had collapsed, all the windows except those on the second storey could not be salvaged, and most of the decorative mouldings were either damaged or missing. Aerial view of Tanjong Pagar in the 1980s No. 9 Neil Road Colour Scheme Documentation of the shophouses revealed that the paintwork was of a narrow colour range, chosen to enhance the natural colouration of the construction materials used. The colour schemes included pastel Restoration Works green, blue, white, creams and buffs, and deep red with occasional splashes of lilac.

Besides The existing double pitch roof of the shophouse was one of its most these, staircases were repositioned such that they lead to external distinctive features.

Airwell With the recovery of the air-well as an open area, the shophouse interior was no longer the dark and stuffy space of old, when the air-well was partly covered and used for other purposes. A surprise discovery was made here with the Chinese water-colour frescoes found below the air- well parapets. When the layers of paints were scraped away, centuries old paintings of flowers and birds were once again revealed. The finished product

Hacking the wall The internal wall plaster was hacked away and the walls treated with a special chemical to bind the bricks together. This hardened the wall and

Recrafting ornamental motifs provided a very good base for new wall plaster. Before this treatment, the surface of the wall was so powdery that it could be removed easily with a stroke of the hand.

Wall Ornamentation and Restoration The façade walls of the shophouses were beautifully decorated with ornamental plasterwork and intricately moulded motifs. Great care was taken to preserve these features and restore damaged and missing ones. The existing plaster work was of lime mortar. In the repairing of the As a showcase project, No.9 Neil Rd attracted visits from dignitaries walls, similar lime mortar was used to accommodate movement and such as Prince Albert of Belgium and the then Minister of National to allow the brick walls to ‘breathe’ - qualities which cement mortar Development, Mr S Dhanabalan.

Replacing the timber staircase and windows The existing timber doors and casement windows with fixed and adjustable timber louvres were retained as far as possible. Replacements were of a compatible type. Existing timber boards which had deteriorated were replaced with new boards of the same thickness and width as the original. The grain of the timber was exposed to reveal on the natural beauty of the wood. Most of the existing staircases had been replaced by the former occupants with sub-standard structures, while the remaining originals were in bad condition. In the restoration work, new staircases to the original condition were installed.
