State Courts Towers by Serie+Multiply with CPG Consultants win Design of the Year Award at The President*s Design Award (P*DA) 2023

At the President*s Design Award (P*DA) ceremony held at The Istana on the evening of 12th July 2023, the State Courts Towers was named the Design of the Year 2023. Designed and completed by Serie+Multiply Consultants Pte Ltd and CPG Consultants Pte Ltd, the design team members behind the project were presented the award by Singapore’s President Halimah Yacob.

The President*s Design Award (P*DA) is Singapore’s highest honour for designers and designs across all disciplines. Awards are conferred under two categories, Designer of the Year and Design of the Year. As a winner of the Design of the Year (Architecture), the State Courts Towers was commended for being a building that resonates with the public and one that referenced the typical architecture of the surrounding site. The jury commented that the direct and effective design reinvents the classical image of courtroom complexes for contemporary times while embracing and addressing the space complexities that create a new kind of court complex.

The P*DA Awards recognises the State Courts Towers as an exemplary project that demonstrates excellence in four areas:

- Enabling economic transformation

- Raising the quality of life

- Advancing Singapore’s brand, culture and community

- Making ground-breaking design achievements  

Enabling Economic Transformation – Improving Internal Processes

The State Courts Towers contributes economic benefit due to its siting and massing. The project started in the late 1990s when it was determined that with increasing caseloads, the former State Courts building (commonly known as the Octagon) would need more space to fulfil its functions efficiently. The surface carpark adjacent to the Octagon was considered for development, however given the space requirements and the physical constraints of the site, a new approach to courthouse architecture was needed. From this, CPG conceptualised building the first high-rise courthouse in Singapore that would not only provide ample space for expansion but allow the existing Octagon building to be occupied by the Family Justice Courts, effectively forming an integrated judiciary hub. By occupying a former surface carpark at Havelock Square, the scheme avoids the impacts and costs associated with procuringnew land. And by proximity to the Family Justice Courts, both judicial bodies can share amenities and resources and thus operate more efficiently.

Architecturally, the tower form is inherently economical by the measure of its higher density (floor area to plot area). It is also an environmentally sustainable building, with abundant natural lighting and innovative green building features incorporated in its design, such as solar panels and rainwater recovery systems, qualifying it as an energy-efficient workplace.

Raising Quality of Life – Enhancing User Experience

The project improves the day-to-day experience of users in several ways. The open façade of the Court Tower allows for lushly planted terraces to surround the various courtrooms. The terraces accommodate informal gatherings and give occupants places to seek respite from the often demanding and stressful experience of legal proceedings. By introducing landscaping on the tower, the project also pushes the idea of urban skyrise greenery, even within a judiciary building.

Separating the Court and Office towers also has several direct benefits to users. By pulling apart the massing and creating shallower floorplates, the building enjoys excellent access to natural light. Also, careful planning of its 53 Courtrooms, 54 Hearing Chambers, and clear segregated user routes (Judges, Persons-in-Custody, and the Public) has improved wayfinding and simplified operations.

Advancing Singapore’s Brand, Culture and Community – Promoting Singapore’s Architectural Identity

The design of the State Courts Towers references the “typical architectures” of the site, merging the design language of traditional shophouses and contemporary high-rises into something that is both new and familiar. It is through this translation that the project contributes to a modern Singaporean brand that equally acknowledges its history. One can recognise the same materiality and granularity inspired by the colours and textures of the existing terracotta roofs of surrounding shophouses expressed onto the courtrooms. When pictured adjacent to the old Ministry of Labour Building (current Family Justice Courts), a connection is drawn between the masonry pilasters of the 1928 building and the articulated columns of the Court Tower.

Making Ground-breaking Design Achievements

The State Courts Towers breaks new ground by exploring courthouse design in a high-rise typology. Eschewing the idea of a tower as a simple extruded form with repeated floor plates and equal floor-to-floor heights, sealed by air-tight glazed curtain walls, the State Courts Towers is a high-rise complex composed of multiple platforms with variable heights. Its open facade frames a series of landscaped public spaces in the sky.

Its unusual vertical form also offers new ideas for development in high-density cities. The project reinforces Singapore as an incubator for innovative high-rise architecture and rethinks both the courthouse and high-rise typologies in a manner representative of contemporary architecture in Singapore. It is open, green, and while informed by historical precedents, offers a new vision of civic architecture.

(1) Vertical Stacking and Circulation

(I) Stacking of Programmes

The simplicity of the design of the two towers provides a clear organisational diagram. All the primary court functions are placed in the court tower – courtrooms, witnesses’ rooms, holding rooms, court officers’ rooms, exhibit rooms and public waiting areas – with the supporting programme including the judge’s chambers in the office tower.

(II) Various Court Tray Types

There are different combinations numbers of courtroom boxes on each ‘court tray’. The court tray consists of two main heights – double volume and single volume. The landscape design of the sky terraces differs because of these two factors. There is no external glazed facade.

(2) An Articulation of Terracotta Tiles

The courtrooms have been designed in a contemporary language while conveying a sense of stateliness and dignity. Outwardly, the open frame design is an apt reflection of the transparency and fairness of the judicial system. In responding to historic Chinatown, the courtrooms are clad in pigmented pre-cast panels measuring 5 to 12 metres in height, with tones inspired by the colours and textures of the terracotta roofs of Chinatown’s shophouses.

(3) Modern Courtroom Design Planning

The State Courts Towers sets a criterion for modern courtrooms with its functional layout, contemporary interior design concept and smart technology.

  • A functional and typical courtroom layout needs to cater for the public, judges, court officers, counsel, persons-in-custody docks, media and transcribers.
  • Zoning of the 3 main users and mindful of the 3 separated basic circulations – Judges, Persons-in-Custody and the Public also happens on a micro scale in the courtroom layout.
