What’s next is almost here.
On July 16th at 1PM ET, beehiiv is going live with a look at the future of publishing, audience growth, and digital business.
What started as a newsletter platform has evolved into something much bigger: a place where creators and brands can grow, monetize, and own their audiences without stitching together half the internet to make it work.
The next chapter starts live at the Summer Release Event.
Join us to see what’s coming next.
Hi there,
Most of the work in architecture now is retrofit. Extensions, conversions, refurbishments, deep retrofits - existing buildings, not blank sites. And yet almost every technology stack on the market is still designed as if you're starting from nothing.
That gap is this week's throughline. I put together a 2026 stack built specifically for existing buildings - scan, layouts, spec, compliance, material reuse - and the interesting part isn't any single tool. It's that the tooling has finally caught up to where the work actually is.
Three things this week. The existing-building stack. The AI compliance landscape, which has gone from a handful of tools to fifteen-plus in two years. And a diagnostic that names the real constraint - which, for most practices, isn't the software at all.
Let's get into it. 👇
What Sparked the Most Discussion This Week
1. Most building work now is retrofit, not new build. So why is every tech stack built for a blank site?

2. AI compliance checking is becoming a category architects need to know - here's the full landscape. (most discussed)

3. Most practices think they're behind on AI. They're not. Everyone is.

Theme of the Week
The bottleneck moved
Three posts, one underlying shift: the technology is no longer the hard part.
Look at the retrofit stack. Two years ago, building a credible tech stack for existing buildings meant gaps everywhere - the scans was clumsy or 2D, the layouts were manual, the compliance check didn't exist. Now there's a tool for each stage, most of them affordable, most working inside or alongside Revit. The work moved to retrofit and the tooling followed.
The compliance landscape says the same thing louder. A category that had a handful of players two years ago now has fifteen-plus, segmented by where they sit in your workflow - inside the BIM model, across drawing sets, through full specification intelligence, into code research. That's not hype. That's a category maturing fast enough that the question is no longer "does a tool exist" but "which stage of my process has no visibility."
Which is exactly what the diagnostic post argues. Most practices think they're behind on AI. They're not - everyone is. The tools exist, they're proven, and they're affordable. What's broken isn't access. It's how the decisions get made: reactively, on partial advice, with no one owning the change.
So the constraint has moved. It used to be the software. Now it's the decision-making around the software. The practices that pull ahead won't have the best tools - they'll just choose better, and match what they buy to where their work actually is.

One Role Worth Noticing This Week
“Bentley is creating an open platform for the built and natural environment to empower software developers to build digital twin experiences. We believe in advancing the platform for the collective success of the ecosystem and equipping the software developer community with open source and open standards. Our work has broad reach ranging from the world’s largest construction companies to the US government to FOX Sports on NFL SUNDAY. Cesium has more than 10,000,000 lifetime open-source downloads, and the Cesium ion cloud reaches more than 20,000 monthly active developers.
We’re looking for a Principal Product Manager in Bentley’s Platform team dedicated to being a liaison and advocate for Bentley’s next-generation iTwin-native cloud-connected AI-powered products building deeply collaborative and iterative relationships built on authenticity, trust, and mutual success. This role will be the glue between Platform’s low-level broad-use APIs and the next-generation infrastructure design and concurrent editing applications.”

What this issue means for practice leaders;
If most of your fee income comes from work on existing buildings - and for most practices it now does - then a stack built for blank sites is quietly costing you time on every project. The fix isn't ripping out Revit. It's auditing the work around it: where does scanning still eat days, where is compliance checked by eye, where does spec get retyped from scratch.
Two practical moves this week:
- Pick one stage of a live retrofit project that has no tooling and trial a single tool against it. One stage, one tool, one project. That's how change actually compounds.
- Before you buy anything, get honest about how the decision will be made and who owns it after purchase. The tools rarely fail. The unmanaged rollout does.
The practices pulling ahead aren't the ones with the longest tool list. They're the ones matching what they buy to where the work actually is.

It was so hot last week I had to shower Richard to cool him down.
