Unexpected Finds That Redefined An Approach to Adaptive Reuse
Adaptive reuse projects often reveal more than anyone expects once demolition begins. In this round-up, architects share the unexpected discoveries uncovered during renovation and explain how those moments reshaped their design decisions. These stories highlight how listening to an existing structure can lead to more thoughtful, responsive outcomes.
Preserve Hidden Trusses Rethink The Roof
Dealing with a structural renovation for adaptive reuse is like peeling back layers of a complicated, forgotten roof design. The project involved converting an old 1930s commercial dairy building into a modern office and community space. The structural goal was to preserve the industrial aesthetic while ensuring the building could carry a new, modern load.
The fascinating discovery came when we removed the original barrel vault roofing and discovered that the concrete decking had been poured directly over an intact layer of early 20th-century wood planking, all held together by a network of massive, hand-cut timber trusses. This timber was not visible from below and was of a higher, denser quality than anything commonly used today. The discovery created a structural failure in our original plan, which was to replace the entire roof support system with modern steel beams. The original structure, though old, was robust enough to handle the new membrane and rooftop equipment load with minor reinforcement.
This discovery significantly influenced our approach by forcing a hands-on compromise. Instead of prioritizing speed and simplicity by replacing the timber with new steel, we prioritized the structural integrity and historical authenticity of the building. We decided to painstakingly reinforce the original timber trusses where needed and then treat them for preservation, leaving the exposed wood as a key design feature in the new office space. This saved the client significant money on materials and labor, and it turned a hidden structural necessity into a focal point. The single lesson we learned is that the best adaptive reuse project is one committed to a simple, hands-on solution that clearly respects and integrates the original, proven structure.
Leverage Concealed Returns For Smart Duct Routes
While Honeycomb Air doesn't specialize in full building adaptive reuse, we often deal with HVAC installations in older, historic San Antonio homes that are essentially major adaptive reuse projects for the homeowner. We were once brought into a 1920s craftsman that was being converted into a modern office space, which meant totally gutting the structure and installing modern climate control without visible ductwork.
The fascinating discovery we made was the original, hand-built network of dead-air returns hidden inside the wall cavities. Before modern duct systems, these were intentional gaps used to passively draw air back to the furnace. It was a crude, brilliant piece of century-old engineering. Our team was about to seal these up, but instead, we decided to study the path they used and realized they provided the perfect structural footprint for running the modern, narrow-profile ducting required for a mini-split system.
This discovery profoundly influenced our approach by proving that older methods often hold the key to modern solutions. It taught us to respect and utilize the existing infrastructure instead of just tearing everything out and imposing a new system. By adapting our modern HVAC design to those original, hidden pathways, we saved the client significant cost on demolition and structural modification. It reinforced that the best service is always about clever integration, not just brute-force replacement.
Expose Superior Concrete Beams Shape Design
During a renovation of a 16-year-old villa in Palm Jumeirah Dubai, we uncovered something surprising after removing the low false ceilings: raw, industrial-grade concrete beams that were hidden for aesthetic reasons.
In Dubai, where modern builds are often optimized for speed and cost, discovering this 'over-engineered' structural integrity was a shock. The concrete quality was far superior to what we typically see in newer standard developments.
This influenced my approach immediately: Instead of covering everything up with gypsum as planned, we pivoted. We convinced the client to sandblast the concrete and leave it exposed, turning a structural necessity into the home's main design feature.
It taught me that in adaptive reuse, the best 'new' design element is often already there, hiding behind cheap plaster. Now, I always perform 'exploratory demolition' before finalizing designs sometimes the building makes the design decisions for us.
