Sonos Era 100 vs. Five for a steel-framed portable office?

Hi everyone,

I am currently fitting out a new detached home office which is a 10x20 steel-framed portable unit (you can see the structural specs and interior layout here: https://portaking.pk/).

I want to create a seamless "Work from Home" audio environment, but I have a few concerns about the acoustics in a metal-clad building:

Acoustics: Because the walls are steel-framed with sandwich panel insulation, I’m worried about reflections. Would a pair of Era 100s be enough for a space this size, or should I go with a single Sonos Five to get better depth in a "tighter" acoustic environment?

Connectivity: Since the cabin is essentially a metal box, I assume the WiFi signal from my main house will be weak. If I run a dedicated ethernet cable to the unit, can I use a Sonos Boost or just hardwire one speaker to create a stable SonosNet inside the cabin?

Mounting: Has anyone had success wall-mounting Sonos speakers on modular sandwich panels, or should I stick to floor stands to avoid vibrations against the steel frame?

I’d love to hear from anyone who has set up a Sonos system in a modular or "tiny home" style office!

Thanks!

10x20 is a bit large for a 100 Pair or a single Five. Maybe a 300 Pair or Paired Fives.

The Fives have built-in Ethernet and might be more convenient. Newer Sonos speakers do not create or use Sonosnet. 

Have you considered either using a wired mesh or an Access Point so everything in the space will have good Wi-Fi? 

As the Boost is long obsolete and far more limited than either of the previous options it is a bad choice.

Mounting is really a "is there a solid place to screw them" issue than construction type issue. If the panels are inadequate a plywood or strand board backing would do the job. I don't notice any vibration issues with my Sonos and they are in a variety of locations on different surfaces.

Reflections aren't going to be solved by speaker selection, even placement will have minimum impact. Get the speakers you want, adjust them to the room and see if you need to add room treatments. You might need room treatments even not considering the speakers if the room is unpleasant to be in.

    To fill the space with sound, I believe that two speakers playing together will give a better spread than one playing loudly. The latter risks being too loud when nearby if it’s to be loud enough when furthest from it. 
    Era 300’s do give a good spread of noise. I have them as a stereo pair, but am often surprised at how well I can hear sound from the other speaker even when standing close to one.
