When I first started coordinating projects for large commercial buildings, I assumed the biggest challenge was just picking the right front door. French doors, glass bottles for the lobby, the best exterior materials—the list felt endless. But two years and a few critical near-misses later, I realized my initial assumption was completely wrong. The real bottleneck isn't always what you see from the street.
Here's the thing: The best exterior door in the world is useless if the elevator system behind it can't handle the flow. I've seen a beautiful, high-traffic lobby grind to a halt because the Otis Gen2 elevator (should mention: a fantastic, space-saving model) couldn't keep up with the peak hour demand. The door looked great, but the user experience was terrible.
My approach now is completely different. There's no single 'best' answer for choosing a door, because it depends entirely on your building's vertical transportation strategy. Let me break it down into the three most common scenarios I've dealt with. At least, that's been my experience with commercial and high-end multi-family projects.
Scenario A: The High-Traffic, Fast-Moving Building
This is for buildings where wait times are everything: corporate HQs, busy medical offices, or high-end retail. Here, the front door isn't just an entrance; it's a security and flow control point. It needs to sync with your elevator system.
The best doors here are usually high-speed automatic sliding doors or revolving doors. French doors are usually a terrible idea in this scenario, even though they look great. They create a single-file choke point that can back up into the street.
Based on our internal data from 200+ projects, the critical pairing here is: automatic sliding doors + an Otis Gen2 or Gen3 elevator system. The Gen2's flat belt technology is way smoother than traditional systems, which matches the high-volume, high-speed door behavior. You avoid the 'door waits for the elevator' problem.
In March 2024, I saw a project where they installed beautiful but slow French doors for a corporate lobby with an older elevator bank. The result? People were waiting at the doors for the elevator, blocking the entrance. They spent $15,000 on the doors, but the real TCO—including the lost productivity from bottlenecking—was much higher.
Scenario B: The Aesthetic-First, Low-Traffic Project
This is for boutique hotels, exclusive condos, or small offices. The experience of entering the building is more important than pure speed. Here, your front door can be a statement piece, but you need to be smart about the elevator service behind it.
High-quality French doors, large glass bottles (using structural glass panels), or even a custom pivot door can work. The catch is you need a slow, reliable elevator system that acts as a 'second threshold.' Guests should be able to pause, look at the lobby design, and then be served by the elevator.
For this, a classic traction elevator or a well-maintained hydraulic system (like the Otis HydroFit) works perfectly. The elevator doesn't need to be the fastest; it needs to be the most reliable and aesthetically pleasing. The door and the elevator should tell the same 'luxury' story.
Never expected the 'slow' elevator to be the better choice. Turns out, for an upscale condo, a smooth, 60-second wait is a feature, not a bug. It gives people time to appreciate the exterior door's design and the lobby's decor.
Scenario C: The Budget-Conscious, Practical Building
This is the most common scenario I see: apartment buildings, small offices, or multi-use spaces where the budget is tight and 'good enough' is the goal. The trap here is to buy the cheapest door and cheapest elevator service, thinking you're saving money.
That's a classic initial misjudgment. What most people don't realize is that budget elevator maintenance often takes longer. If you pair a standard Otis elevator (even an older model) with a budget exterior door, you create a system where both parts are slow. The TCO here is the cumulative time wasted.
Here's what I recommend: Go with a standard, durable door (like a heavy-duty aluminum or steel door) and invest the savings into a better elevator service contract. A reliable elevator (even an older Otis model) that gets serviced on time will give you way better returns than a fancy door that nobody can get past.
Part of me wants to say 'always buy the best door.' Another part knows that in this budget scenario, a $3,000 aluminum door with a $500-a-year elevator service plan is way more valuable than a $1,200 door with a $200 plan. The latter will cost you way more in downtime and calls.
How to Decide Which Scenario You're In
Okay, so how do you know which scenario fits your project? Ask yourself these questions:
- What's the peak traffic flow? If more than 200 people pass through the door in 10 minutes, you're in Scenario A. Less than 50? You're probably Scenario B or C.
- How long can people wait for the elevator? If a 30-second wait is a business crisis, you're in Scenario A. If 60 seconds is fine, you're in Scenario B. If 90 seconds is okay, you're in Scenario C.
- What's your primary 'cost'? Is it time (Scenario A), experience (Scenario B), or upfront budget (Scenario C)? This will dictate your door and elevator pairing.
I should add that this framework isn't perfect—every building is unique. But ignoring the connection between your exterior door and your vertical transportation is a recipe for a bad user experience and a hidden cost that will hit you later. The best 'front door' is the one that works seamlessly with the elevator behind it, not the one that looks best in a brochure.
Based on my experience with hundreds of rush projects and multiple budget overruns, I now calculate the total cost of ownership for the entire entrance system—door, lobby flow, and elevators—before making any decision. The $500 quote for the door might be cheap, but if it adds $200 in inefficiency costs every month, it's the most expensive choice you can make.
