Navigating the New Era of High-Rise Residential Construction

When Willmott Dixon took on the challenge of delivering 297 apartments across two schemes in Bristol's city centre, we knew we were entering uncharted territory for us in Bristol. The Millwrights Place and Coopers Court project would become our tallest residential building to date in the region, and a proving ground for the new Building Safety Act requirements that were emerging at the time and reshaping how we build high-rise homes.

The result? A defect-free completion that building control inspectors called "exemplar good practice," earning our project director Dave John a gold medal at the Construction Manager of the Year awards.

The Building Safety Act Challenge

While this project did not technically fall under the new Building Safety Act and secondary regulations it was very much on the horizon, we therefore decided to adopt the principles we knew were going to be requirements for the future. Where traditional builds might generate thousands of documents, this project required 35,000 pieces of documentation—including 8,000 photographs and comprehensive quality checks that formed a detailed building file for future reference.

"The vast majority of our 25-person team had never worked on high-rise residential before," explains Dave John, who led the project. "We had to completely rethink our approach to materials, documentation, and team structure."

Key changes included:

• Zero combustible materials in the building envelope - even simple items like plywood patresses for radiator fixings were banned
• Rigorous documentation from day one, requiring specialized resources and skill sets
• Enhanced quality processes with multiple sign-off stages and detailed photographic records

Halfway through construction, building control invited the new regional Building Safety Regulators team to visit the site. Their verdict? The project demonstrated best practice in the industry's new regulatory environment.

Solving Complex Urban Logistics

Building in Bristol's city centre presented logistical challenges that demanded innovative solutions. The site housed three tower cranes, 29 mast climbers, and three goods hoists—all while maintaining 24/7 access to an active fire station next door.

Our solution: We established an off-site storage yard in Yate, North Bristol, near the M4/M5 interchange. This allowed us to secure materials like brick slips, insulation, and cladding components away from the constrained site, calling them in precisely when needed.

"It's an added cost having materials delivered twice," John notes, "but it was money well spent. We could maintain our construction program without compromising the neighbouring fire station's operations."

Innovation Through Prefabrication

Learning from previous projects, we revolutionized our approach to balcony installation. Rather than the traditional method of individual steel erection and fitting—which required multiple trades to access finished apartments—we employed prefabricated balcony systems.

The transformation was remarkable: Nine to ten balconies could be installed daily, with balconies manufactured off-site and stored until needed. Beyond one operative guiding them into position, no one needed to enter completed apartments, dramatically reducing remedial work and maintaining quality standards.

Managing Complexity at Scale

For a project of this scale, nearly 300 apartments across 14 stories, traditional management approaches wouldn't suffice. We developed what became known as our "coloured boxes schedule," dividing work into specialized zones with dedicated two-person management teams.

Each "box" represented a specific phase:

• Blue box: First fix partitions and M&E installation
• White box: Sign-offs, backboard, plaster, and mist coat
• Red box: Kitchen and bathroom fitting
• Yellow box: Final snagging and commissioning

This system allowed managers to focus on their specialized area while maintaining clear handover points, ensuring quality and efficiency throughout the vertical construction process.

Quality Through Preparation

Before constructing a single apartment, we established a quality room showcasing every tap, sink, and shower head for customer approval. This led to sample apartments for each scheme—a critical step that ensured all 297 units met exact specifications.

"You wouldn't want to make a mistake 300 times," John emphasises. "The sample apartments were vital for residential work of this scale."

Delivering Results Under Pressure

Despite facing challenges including adjacent development delays, district heating connection postponements, and the complexity of dual end-users (Granger PLC for rental apartments and housing association Abri for affordable homes), the project achieved remarkable outcomes:

• Defect-free completion certificate for both schemes
• Seven-month extension managed professionally with full client collaboration
• Industry recognition as exemplar practice for future Building Safety Act and secondary Building Regulation compliance
• Gold medal for Dave John at Construction Manager of the Year awards

Looking Forward

The Millwrights Place project has become a blueprint for high-rise residential delivery in the post-Building Safety Act era. Our experience demonstrates that while new regulations require enhanced resources and different approaches, they ultimately deliver better buildings and safer homes.

Key takeaways for future projects:

• Early engagement with Building Safety Act and Building regulatory requirements is essential
• Off-site manufacturing and prefabrication offer significant advantages in constrained urban sites
• Specialised management systems are crucial for complex, multi-story residential developments
• Investment in proper documentation and quality processes pays dividends in final delivery

For developers and housing providers navigating today's regulatory landscape, the project proves that achieving defect-free delivery is possible—but it requires partners who understand both the technical requirements and practical realities of modern construction.

The success of Millwrights Place represents more than just another completed project—it's evidence of how construction expertise must evolve to meet 21st-century housing needs while maintaining the highest safety and quality standards.
