The “Chadstone Link”, a stylish and weather-protected walkway, links the Chadstone Shopping-Center to the new office tower “Tower 1” and to the new MGallery of the Sofitel-Hotel Group.

On a length of 110 metres, the spaciously designed and multi-purpose area in one of the largest shopping centres of the southern hemisphere provides manifold possibilities for exhibitions and many other events. The 31 differently dimensioned and individually formed timber arches made of glued laminated timber elements by Rubner Holzbau harmonically connect to the arched glass roof of the adjoining building complex and reach, at their highest point, a height of 15 metres. A highly translucent PTFE-cloth positioned on top of the glued laminated timber structure provides for lots of natural light.

Nested in a green park in the Cumberland City Council, West Sydney, the new Eric Tweedale Stadium, named after a “living legend” of the Australian Rugby, is a new construction of a Grandstand for 750 spectators with change rooms, multipurpose room, office, amenities, community function room, canteen, kitchen and a covered viewing deck.

The construction is part of the development of the rugby field that is home to Two Blues Rugby Union Club and will be visited by thousands of sport fans during rugby season. The timber structure that was detailed designed by Rubner Holzbau form part of the top floor of the grandstand and is cantilevering for over 8 mt on top of the seating. With a footprint of about 1.000 sqm, the structure was segmented for transport in container with concealed, factory-assembled connections for a pleasant aesthetic outcome and a guarantee of a quick erection.

In the Australian suburb of Marrickville, the listed building of the former hospital was preserved and restored to now form part of the newly built library. This newly created library has been defined as multi-purpose community facility whose innovative design combines the most state-of-the-art technologies and sustainability.

To be able to execute this project, 54 round columns had to be built with different lengths reaching from 3 to 9.3 metres. Trimmed and round milled on a CNC-controlled machine installed in the Rubner factory, some 90% of these timber columns support the roof structure of the building - an oversized floating canopy roof inspired on the old hospital roof. Five additional timber columns simultaneously bear the load of one part of the roof and of the façade including the railings. These columns provide an open space feeling since the library’s main atrium, which allows to take a glance at the major areas in the newly installed three-storey building, hardly has any suspended ceilings.

Theca has designed and engineered a swimming pool modular roofing structure. These modular builds, which are engineered on the bases of a regular rectangle with a dozen combinations of widths and lengths to suit any type of outdoor pool area based on the properties of engineered timber construction.

Their executive design can be easily extended or reduced in size thus immediately adjusting to changing requirements. The 100% prefabrication of this basic structure reduces construction periods compared to conventional construction methods.

An iconic new gateway for the region, the Batemans Bay Regional Aquatic & Arts Leisure Centre, is set to become a drawcard for sports, tourism and regional arts programs.

The new center, featuring an ecologically sustainable development principles design, is composed of two distinct pavilions. One houses three pools, a gymnasium and waterslide tower, while the other boasts a 350 retractable seating black box theatre, rehearsal room and art studios. The streamlined central building connecting the two pavilions complete the building with main reception, foyer and administration areas. We provided over 140m3 of spruce glulam treated with a coating suitable for pool environments. The maximum span of the longest elements is 33mt, split into three smaller parts for transport reasons. The original design was calling for a bow-string type of hybrid beams, with a solid flat top glulam part and a tension cable below. We were able to execute the design intent by adapting each dimension for load verification, manufacturability and ease-of-installation. The outdoor pergola is equipped with bespoke 3D bended glulam elements (beams that are freeform bent in two directions) that represents the waves of the nearby ocean, and also the Architect signature on the job.

Destined to become one of the most significant social and tourist destinations in the city, the new Sydney Fish Market represents a flagship project of the New South Wales government, that will support tourism and the fishing industry, creating a world-class landmark.

Located in Blackwattle Bay in Pyrmont, two kilometres west of the business district of the capital of New South Wales, the Sydney Fish Market is the third largest fish market in the world. The 65,000 square metre renovation project was commissioned from Danish design firm 3XN, working with local architectural firms BVN, GXN Innovation and landscape architect Aspect Studios. It will take about 1,600 m3 of spruce glulam, over 150 tons of steel and all the know-how of Rubner Holzbau to manufacture the large roof that floats above the new Sydney Fish Market, connecting all the elements of the structure in a unique elegant movement that gives the building an iconic presence. The building's roof is an integral part of the new Sydney Fish Market's iconic design, but also a standard bearer for its sustainability strategy. It is in fact designed to collect rainwater for reuse, for the potential production of solar energy. Its unique shape uses the winds to extract warm air and protect workers from the southerly winds. The canopy, made of wood and aluminium, is designed to be as permeable as possible, minimizing the need for air conditioning while diverting direct sunlight. The triangular openings allow plenty of natural daylight into the building, while their orientation shields the building from the sun during the hottest hours.

Upper House is a breath-taking new residential tower in South Brisbane, designed by Koichi Takada Architects and inspired by the forms of the Daintree Rainforest. It’s set to become a new benchmark in luxury apartments in the city, featuring Australia’s first double-storey rooftop club.

The fluid sculptural ‘ribbons’ of the building set it apart in the streetscape and wind their way up the facade in reference to the roots of the Moreton Bay fig tree native to Queensland. At roof level, the ribbons twist and intertwine to become a shaded pergola for the generously proportioned recreational spaces. Theca Timber was involved from the very early beginning, participating in the tender hand-in-hand with Minicon and consulting on the most cost-efficient way to build what, before then, was a concept design. The continuous interaction and collaboration with KTA resulted in a Siberian Larch glulam pergola made of slim, load-bearing main ribs, featuring double- and triple-bent elements fabricated with a 3D special technology from our European Partners, and over 1,6 km of timber purlins for shading. Further to the scope above, Theca Timber was awarded the design and supply of two 9mt tall unique structures, called The Nests. Positioned at the 32nd floor of the tower, The Nests are timber rounded platforms forming a suspended parlour on top of the pool area, surrounded by an intricated freeform mesh of Ash Tree timber providing shelter and privacy.

Northcote Aquatic and Recreation Centre is a swimming centre that serves the Darebin City Council community. When the previous facility reached the end of its life after more than half a century service to the community, the Council decided to build a brand new, eco-sustainable centre targeting for net zero emissions.

Warren and Mahoney, the Architect, and TTW, the Structural Engineer, designed a glulam roofing structure featuring 31mt long beams, bracing and secondary elements, and the entire ceiling structure formed by a cassette system. Together with our partner Rubner, we were contracted by Kane Construction, the General Contractor, to consult for the most efficient timber structure based on the architectural model, and to bring the tender design to fruition by including as much as possible prefabrication factor into the supply. Most of the timber connections and 100% of the ceiling cassette were factory assembled in Italy, resulting in a quick installation with millimetre precision.

Located in the heart of Darling Harbour on Sydney’s CBD fringe, once upgraded, Tumbalong Green Stage will accommodate a rich space for mixed community events and entertainment uses.

The upgrade includes raising the performance stage, new lighting system and AV equipment, but the star of the project is undoubtedly the construction of a new steel and glulam timber structure, with membrane roof on the top. The concept design is done by Hassell, while the preliminary engineering and the full 3D modelling is to be completed by Sydney-based structural engineer TTW. Theca Timber task, through its specialist consultant team of timber professionals, is to bring the design to manufacturability, transportability and ease of erection. The complexity of the structured is pictured by numbers, with over 200 timber members of different dimensions, shape and connections, and north of 800 bespoke steel connections. Last to be considered is that the supply of the entire structure for which Theca Timber has been contracted to happen in record time, just 4 months after 100% design definition. In fact, project completion is due in time for the 2023 Fifa Women’s World Cup, which is going to gather hundreds of football fans and passionate in front of the mega-screens installed under the shell.

The Greater Metropolitan Cemeteries Trust nominated Melbourne-based studio Searle x Waldron Architecture to design their new multi-purpose, operations depot located in Sages Rd. Aimed to be a new gathering place for employees, including offices, meeting rooms, lunch room, collaboration Spaces, an Auditorium, as well as vehicle parking, workshops and storage area, the building was designed as a series of parallel glulam trusses, having different heights and shapes, using CLT to create the first floor slabs and a series of stairs connecting ground to first floor. Walking corridors through the building are designed under the V shaped trusses diagonals, and they had to be closely coordinated together with the services running through the timber structure.

Theca Timber was requested for a full service of consulting through the design, targeting for the respect of the Architectural Design, and the optimisation of the trusses for production and assembly. Our Team engaged different manufacturers to coordinate suppliers from several sources, creating an LOD400 model ready to be declined into machine files for the hi-tech CNC robots governing the production of complex glulam connections.
