‘The Future of Student Living’, a panel discussion hosted by Walsh on 19 March, took a look at 2 recent PBSA tasks whose viability has been positively affected by engineering style. Images Timothy Soar, JRL, Urbanest The two projects are both for
Urbanest. The first is an 853-bed
plan in Battersea and the 2nd, when completed, will offer 1,672 beds is in Canary Wharf. Both are built to Passivhaus standards, with the Canary Wharf job being the biggest Passivhaus building in Europe. The Canary Wharf job utilized MMC construction methods, lowering construct time and efficiently offering investors an additional academic year of income. Passivhaus is a set of building design principles that reduce energy usage and for that reason
the operational expenses of the building, while likewise offering a comfy year-round environment for residents. For Urbanest, acting as both developer and operator of the structures, the long-term gains make this approach appealing to financiers.”Our financier is really, long term focused in their outlook”summarised Vicky Skinner, CFO of Urbanest.
“They think in investment periods of years and longer … From the point of view of future proofing, delivering Battersea and now Canary Wharf to a Passivhaus requirement seemed like truly fantastic derisking from their point of view, which all helped build the case in regards to practicality. “”Our students are definitely at the heart of everything we do, and our factor for being. Passivhaus was an actually wonderful target to desire and now deliver in these buildings which are so comfortable in regards to their ambient conditions.”< img width=" 1800"height="2400 "src="https://atlive-wp.s3.eu-west-2.amazonaws.com/wp-content/uploads/250718-AHMM-UB-5428.jpg"alt=""/ >< img width ="1800 "height ="

For sustainability architect and Passivhaus expert Thomas Henriksen, developing in energy efficiency right from the start of a task is an integral part of the journey towards achieving structures that are net absolutely no in operation. Doing this needs cooperation from all parties: “Among the things that makes Passivhaus successful is that we worked as a team, right from the customer assistance, the financier support and support from the cost consultant.”
Urbanest regards development as central to its advancement goals, so it was maybe a logical next step to include modern approaches of building and construction into the program for the Canary Wharf building.
For engineers Walsh, already handling a challenging site above a major sewage system and high voltage power lines, the introduction of a hybrid precast system added to the intricacy. Initially developed as a reinforced concrete frame the decision was made to change to a hybrid system to even more decrease the building program.
Modern techniques of building and construction (MMC) are being used to construct the Urbanest area at Canary Wharf, presently on site.
“The structure used precast concrete floor elements which are assembled on site and finished with a concrete topping to develop a monolithic slab. Structurally, the end outcome is almost similar to a standard enhanced concrete piece. The difference lies in how the structure is assembled,” summarised Walsh Director Andy Stanford. “It’s a package of parts, with everything made offsite and then assembled on site. It’s a principle like flat-packed furniture.”
This offsite fabrication idea was utilized for a lot of the structural components. The unitised exterior is produced offsite to stringent Passivhaus compliant efficiency requirements before shipment to website and spaces consist of pre-manufactured bathroom pods that are stacked on site.
“Interestingly, these Modern Techniques of Building didn’t actually impact the architecture” observed Bram van der Wal, Director of Apt designers. “These sorts of things are program items.”
What Modern Methods of Building and construction did affect, nevertheless, was expense and time on website. Rob Barbour of Cast Consultants was responsible for expense management of the Battersea task and approximates that Passivhaus standards will add about 3-5% to structure costs, compared to other high carrying out building approaches.
This uplift in expenses can mostly be mitigated by lowering construct time, as was demonstrated in the Canary Wharf project. “While offsite and hybrid precast services can carry a cost premium, the programme benefits– including decreased preliminaries, improved certainty and earlier completion– can offset this, especially where earlier profession drives extra revenue.”
For Bram van der Wal, Director of architects Apt, there were some instant practical advantages of the ingenious technique taken with the structure styles, particularly at the preliminary stages of gaining preparation consent. Organizers can be unwilling to authorize PBSA jobs, but focusing on the sustainable design of the structures supported regional low carbon aspirations.
“It had to be discussed to the organizers in the first instance … but once they bought into that idea and how it all tied together with the scheme as one holistic, sustainable technique, they were happy to support … It was a consentaneous choice to give authorization, which was a terrific accomplishment.”
Implementing truly ground-breaking innovative structure strategies needs the early buy-in of all the style team, backing from investors and a trusted delivery partner. The style team on the panel were keen to praise specialist Midgard, part of the JRL Group and main contractor of Urbanest Canary Wharf. The close working relationship of all the shipment partners is credited with the smooth-running of both building and construction projects.
With the Canary Wharf project running months ahead of schedule, it is now due for conclusion in summer 2026, allowing for students to inhabit the developing a complete scholastic year before initially scheduled. A considerable additional monetary benefit to come from welcoming modern-day building techniques.

The March discussion was the first in a prepared series of constructing talks hosted at the London workplaces of Walsh Engineering, showcasing their participation in innovative and affordable building approaches. An audience of approaching 100 developers, experts, designers and engineers, showed the broad industry interest in ingenious building methods and likewise the central position inhabited by the Walsh group in supporting the ambitions of these forward-thinking tasks.
