Working on a small bay flex prototype design and thinking about whether to design to allow mezzanines to be added as an upgrade option for tenants. Who has done this? Good idea, bad idea? What clear height did you start with….22’?

I'm currently working through a feasibility study on approx 3.5 acres (narrow, rectangular lot). It seems like it could support 36-40 KSF in 3-4 10,000-12,000 SF buildings. I've been evaluating the market and tenant base which could span from contractor to "higher end tenants". I've talked SBF with other developers and parking ratio seems to be one of the priority variables to address in ground up....direct impact on potential tenants and lease rates. I'm looking for input on these ratios based on market tested experience. Currently, I'm underwriting 2.5-2.75 spaces per 1000 SF. Inviting input and challenges. Thanks in advance to everyone!!

@Will Skillman made an interesting remark about testing market demand with pre-lease ads, and I’m curious if anyone is trying this on marketplace with 3D models or floor plan images. Obviously don’t want to break any rules, but if you could test tenant interest in a region quickly, it would be a huge boon prior to putting earnest money down.

Good morning, everyone. My name is John Mureiko and I own a construction company specializing in light industrial projects. (Don't worry, not here to sell!) I first learned about small bay/flex through YouTube, and found out our company was not only a "flex" user, but that we could eventually develop our own (or partner as JVs). Through groups like this and particularly LinkedIn, I am learning from others constantly about how to perfect the product, how to address challenges, and how I can help support other folks journeying here by reviewing costs, design and process from a builders standpoint. I post regularly on LinkedIn with building tips and advice for how to avoid mistakes in projects like this, so you may find that helpful and I'd love to connect. Thanks for the invite, Will!

Been a week or so since I was last on basecamp so catching up a bit. I've been working to develop both ground up and value add small bay flex in south central PA. Cost is a major focus for me, specifically construction cost. I recognize the construction cost associated with value add can vary widely depending on what you're starting with. I'm looking for input on construction cost associated with ground up dev. I'm working with several contractors to provide more detail on some prototype designs so that I can identify levers to potentially pull to help with deal economics. I'm interested in what others are seeing in cost PSF for vertical ground up construction in your neck of the woods (and scope). It's been challenging to get <$100 PSF but I'm continuing to work on it (PEMB, small office, restroom in each unit, mini split in the office, heat in the high-bay) Appreciate any input and suggestions!
