Penrose Two Headline Facts :

179 reconstructed stone panels, covering 2,841 square meters.

Contractor : Hegarty

Architect : Wilson Architecture

The Finer Details :

Situated on the banks of the River Lee in Cork, Penrose One & Two is a commercial development constructed by Hegarty Construction and designed by Wilson Architecture.  The buildings enhance the emerging skyline at Cork’s docklands and delivers 250,000 square foot of sustainable, Grade A office space.  Situated in close proximity to the historical Penrose House, the buildings designs are based on classical proportions with the intention of embracing and enhancing their historical neighbour.

Techrete was awarded the tender to design, manufacture and install the architectural precast concrete cladding façades for both buildings at Penrose Dock.  

Penrose One is organised in three distinct vertical modules with Techrete’s double height vertical mullions elongating the building’s appearance. Structural precast concrete columns rise from ground level to the third floor, cast in three parts and stitched together, creating a grand entrance to the building and further elongating its appearance.   The precast concrete façade of Penrose Two also consists of mullions and spandrels and the consistency of both façades provides a framing approach to the original Penrose House. 

The chosen mix for the project was Techrete’s C190 with an acid etched finish, with provides a warm soft appearance to the façades. 

Cast-in lettering was used on panels for Penrose One and Two providing elegant signage for the two entrances.

Duncan House

Duncan House, Stratford, London E15 2JB

Duncan House Headline Facts:

1,487 reconstructed stone panels, covering 18,500 square meters.

Contractor : Watkins and Jones

Architect : Hodder and Partners

The Finer Details :

Duncan House in Stratford, London is a mixed-use development which offers residential apartments, student bedrooms, academic space and has a roof garden and sky lounge.  Designed by Hodder and Partners and with Watkin Jones as the main contractor, this development completed in September/October 2019.

The 9-storey podium block of the development defines the street edge and responds to the lower rise buildings surrounding the site.  The podium’s right-angle arrangement within its site allows a significant piece of public realm to be formed at the junction of High Street with Lett Road. The composition of the tower with its fins creates a striking silhouette against the sky.

Techrete were engaged to design, manufacture and install the 1,487 panels, covering the 18,500 square meters of cladding which makes up the façade of Duncan House.  The reconstructed stone mix chosen for the project was C280 with a light pigment and an acid etched finish. 

The structural precast columns to the first floor were manufactured by Techrete and create right angle public colonnade.

Approximately 2,500 windows were fitted at our factory to the panels and the combination of these panels, together with the concrete infill as well as louvres which were also fitted in our factory, make up the façade of the structure.

Creating the moulds for the 1,487 panels with high repetition was always going to be a challenge.  Steel moulds were developed to facilitate this, and bespoke steel cassettes were vital in speeding up the process of casting the window panels in particular.

Three Techrete teams installed the panels using three tower cranes and due to the high-rise nature of the building, the Bomecon counter-balance rig was utilised to assist with the installation while the core structure was still being completed over-head. 

Duncan House is mainly a student residence, and it is a prestigious project to add to Techrete’s student residence portfolio, particularly in the city of London.  Following on from the successful completion of the project, Techrete entered talks with the main contractor, Watkin Jones for the tendering of several other projects.

Duncan House won ‘Best Tall Building – Facade Engineering Project of the year’ at the Tall Building Awards in December 2020 and has achieved a ‘BREEAM Excellent’ rating.

The Finer Details :

The redevelopment of Southbank Place in central London comprises 8 new buildings surrounding the quarter’s centrepiece, the Shell Centre Tower.  The overall redevelopment once completed, will be home to a mixture of offices, residences and retail space and will integrate with open public areas and pedestrian routes.  Techrete were engaged by Canary Wharf Group PLC to design, manufacture and install the precast concrete panels for three of the buildings within the quarter and these were Building 1, Building 4A and Building 4B. 

Self-compacting concrete using Techrete’s C190 mix for a warm off-white colour, was finished with acid etching to lightly expose the aggregate, giving the panels a soft slightly textured appearance.  Granite plinths were also utilised in a Kurum Grey finish and these were supplied to Techrete by Savema. 

On buildings 4A and 4B Techrete’s C190 reconstructed stone mix was also used with an acid etched finish.  Two storey height panels were manufactured with a vertical indentation in the panels up to levels 10, elongating the structures and creating an elegant ribbed effect. 

3D modelling was vital for all three buildings from a Techrete perspective as the extensive steel work of the frames had to be co-ordinated throughout the building.  Two bridges on levels 4 and 8 linking buildings one and two, handrail interfaces throughout the building and the interfacing canope described below, all added to the complexity of the design work.  Some clashes with the mechanical and engineering work were detected at an early stage and rectified by our design team before any delays were incurred. 

GRC soffits were used to clad the over-head areas of the public colonnades on buildings 4A and 4B.

The open structures on the roofs of buildings 4A and 4B were tricky as there were 4 sided columns and beams to negotiate and additionally the steel frames were being built over-head as we were cladding the mid-levels which required a high level of co-ordination and the use of our Bomecon counter balance rig.

Southbank Place 1 appears to step backwards in three blocks from the ground floor to story 5, from level 6 to level 9 and finally, from level 10 to level 14.

The building features 2 and 3 storey height panels, which were 11 metres long.  A major feature of the panels was their extra deep returns on the legs which creates a solar shade and visually achieves the architects design intent.

Self-compacting concrete using Techrete’s C190 mix for a warm off-white colour, was finished with acid etching to lightly expose the aggregate, giving the panels a soft slightly textured appearance.  Granite plinths were also utilised in a Kurum Grey finish and these were supplied to Techrete by Savema. 

A canopy was created down one elevation of building 1 to create a semi-enclosed space linking buildings 1 and 2.  The canope interfaces with the steel work and it was this interface, whilst small in size, was crucial in the overall development of the canope and was incredibly intricate for our draughtsmen to model.

Local Blackfriars

Local Blackfriars, Salford, Manchester

484 reconstructed stone and terracotta faced panels, covering 5,574 square meters.

Contractor : Domis Construction

Architect : Jon Matthews Architects

The Finer Details:

Local Blackfriars is a beautiful gated residential project, comprising 380 apartments, penthouses and townhouses across two striking towers, in Blackfriars, Greater Manchester. The Blackfriar, a Grade II listed former public house, has been repurposed to act as a gateway entrance for the development. This striking look of the towers was achieved using a combination of finishes. Throughout the buildings, the panels consist of a granite based reconstituted stone, with a polished finish and variations of green tiles cast into the panels.

An acid etched finish forms the base and crown or the top of the buildings, which provides the buildings with an elongated appearance. Techrete were responsible for the architectural precast elements of the project and for the structural columns which sit from the base of the buildings to the second floor. These were also produced in a polished, reconstituted stone. A key feature of this project from a Techrete perspective, was the fixing of the balconies directly to the panels on-site, facilitating much simpler construction and installation.

Contractor : Mace

Architect : Populous

The Finer Details:

Tottenham Hotspur’s new 62,000-capacity stadium in north London has made wide use of precast concrete – including creation of the football club’s famous crest and motto.

Tottenham Hotspur Football Club’s new stadium set a new benchmark for sporting arenas in the UK, and the construction work was also of the highest quality.

The 62,000-seater venue in north London, the largest club stadium in the capital, is designed to be multi-purpose and features the world’s first dividing, retractable football pitch, which reveals a synthetic turf pitch underneath for NFL London Games, concerts, and other events.

Designed by specialist stadium architects Populous, with construction management handled by Mace, work on the project got under way in 2015.

Precast concrete has been used widely, including the terrace sections in the seating bowl, vomitories, stairways, concourse, and external areas, as well as spectacular visual signatures of the football club’s identity.

Tottenham’s famous crest, a cockerel standing on a football, and the Latin motto ‘Audere Est Facere’ – ‘To Dare is To Do’ – were created as giant architectural precast panels by Techrete and are visible inside the concourse areas under the seating bowl.

Bespoke moulds were designed for the precast letters. The 27 Tottenham lettering panels measured 2,000mm in length and 2,200mm in width, and each weighed a tonne.

The Finer Details :

Victoria Gate is located in the heart of Leeds City Centre and was designed to incorporate a flagship John Lewis Store and internal shopping arcades. The architectural precast concrete cladding on this inspirational project, demonstrates how far the limits of precast concrete engineering can be pushed. Combining different acid etched and polished finishes within the various sections, a design with intricate geometry and a complex installation process, coupled with the utilisation of BIM 3D design tools, all demonstrates what can be achieved with precast facades.

The diagrid pattern was deconstructed by Techrete engineers to panelise a façade that would fit with precast manufacturing needs and yet not compromise the architectural intent. Overall, the architectural precast concrete cladding on the John Lewis store has created a unique and memorable identity and showcases just what can be achieved with such a versatile product and Techrete expertise.
