I'm going to have 1 row of seating. Shooting for around 13' wide screen, although not set in stone. Home is still being built.

The reason I ask is I don't want to let 3D movies at the cinema pass by if it's not possible to replicate a similar setup in the home. i.e. are we in a 35mm vs VHS scenario where the only way to see the movie in good (3D) quality is to see at a commercial cinema?

It'll work but you'll need a 3D projector that cranks out the lumens and can easily light up a screen that size, especially as the bulb dims. You'll probably need a higher gain screen as well.

Listen up, studios! Just say "NO" to DNR and EE!!

Your suspicions are partly correct. Home theater will not replicate the cinema. The good news is that home theater 3D can easily be better than the cinema - just not as large. If you aim for a 10 ft wide screen, you can get a fantastic 3D picture. Look at the Epson 5010.

Most every home theater projector is designed for a screen 10 ft wide or less. You lose too much brightness and with that, you lose impact when you go for a larger screen. A 10 ft wide screen viewed from 10 to 15 feet away is super great. Put in a few subwoofers and a high power surround sound system, and you will have home theater experiences you will never trade away.

This goes triple for 3D, as the glasses rob some brightness. At 10 ft wide, 3D works impressively.

My 2 cents on your question. I am in no way an expert.

On the subject of screen size.
I dont know if your doing 16:9 or Anamorphic. The ratio may affect your lumens as well if your trying to stretch a consumer level projector to the max (someone more into Anamorphic than me can correct me on that). Not only is Lumens an issue with a 13' screen size. You may have screen door effect as well. At 13' you may want a higher caliber of projector than a normal consumer. If your tool box consist of a check book and nothing else then maybe you will be ok.

On simulating commercial grade 3D
There is a review on projector central regarding a polarized lens mounted on the front of the projector which eliminates viewers needing active shutter glasses. You still need passive glasses though. This setup gets you closer to the "at the movies" effect for 3D. However this may change up your game plan. They suggest a siver screen for reduced hot spots. At the time of the review the adapter required DLP projectors only. Upon looking at the manufacturers site this may have recently changed to include LCD as well.

I dont know how new the technology is for a consumer, but it seems the local theater is using the same setup. I was at an IMAX 3D showing of Prometheus. I noticed they were using a silver screen. After the previews were over, I noticed a shadow over the screen and thats when the 3D visuals started. Then I remember that commercial grade polarizers move in front of the commercial projector (kinda like a CD rom tray moving infront of a projector lens if you will). Then there was an IMAX promotion/commercial that is was a DLP picture. BINGO!!!

Here is the link to the review.
