US architecture sector experiences longest revenue decline in history
Architecture Billings Index shows 3.5 years of continuous decline amid energy price pressures
1Historic decline
The AIA/Deltek Architecture Billings Index (ABI), tracking US commercial construction revenues since the 1990s, dropped to 46.6 in July. The index has shown uninterrupted decline for 3.5 years, marking the longest negative streak in its history. This surpasses the previous 30-month decline record set after the 2008 financial crisis. All specializations reported decreased billings, with commercial/industrial firms experiencing 4 straight years of contraction.
2Regional breakdown
Northeastern US scored worst at 44.8 (scores below 50 indicate decline). Other regions showed minor recoveries from early-year lows but remained negative. While multifamily residential and institutional firms saw temporary growth earlier in 2024, this momentum faded. Commercial/industrial specialists haven't reported growth since July 2020, reflecting weak demand for office and retail spaces.
3Contract value shrinkage
New project inquiries continued growing in July, though at a slower pace than June. More concerningly, the value of newly signed design contracts decreased after nearly reaching growth the previous month. This suggests developers are becoming more cautious despite initial interest. Construction costs meanwhile rose 7.4% year-over-year since July 2025, compounding financial pressures.
4Oil price impacts
AIA Chief Economist Richard Branch cited high oil prices as a key inflation driver, warning of potential further interest rate hikes in late 2024. These macroeconomic pressures make project financing more expensive for developers, leading to postponed or canceled developments. The construction sector also faces supply chain disruptions and rising labor costs, creating a perfect storm for architecture firms.
5Structural industry challenges
The architecture profession has long struggled with structural issues like fee compression. While current ABI levels (46.6) remain above COVID-19 lows (29.6), the duration of decline is unprecedented. The 2008 crisis caused a 30-month downturn - now surpassed by the current 42-month slump. Residential specialists briefly rebounded in early 2024 but couldn't sustain growth, indicating broader market weakness beyond pandemic effects.
6Specialization performance
Multifamily residential firms saw temporary growth in early 2024 before softening, mirroring institutional project specialists' trajectory. Commercial/industrial architecture firms haven't reported billing growth since July 2020, reflecting persistent weakness in office and retail sectors. This specialization has now endured 48 consecutive months of decline - the worst performing segment in the architecture industry.
7Macroeconomic uncertainty
The AIA report emphasizes how macroeconomic uncertainties continue weighing on construction activity. Beyond oil prices, supply chain disruptions and rising labor costs create additional headwinds. Developers face higher financing costs, leading to project delays or cancellations that directly impact architecture firms' revenues. These compounding factors make the current downturn more prolonged than typical cyclical contractions.
8Future outlook
Analysts warn the decline may continue if inflation and interest rates keep rising, particularly with anticipated late-2024 rate hikes. However, some predict potential 2025 recovery if energy prices stabilize and supply chain issues resolve. The architecture industry's fate remains tied to broader economic conditions, with commercial real estate especially vulnerable to financing costs. Institutional projects may offer relative stability amid the downturn.
