Bids in and the Eterna Building System

Bids in and the Eterna Building System

So the bids are coming in! I asked 3 builders/general contractors to bid out the project based on architectural drawings we finalized a few weeks ago. As you probably know, I’m a bit obsessed with green building materials and really wanted to go with something other than stick construction. I was very interested in Cresco Concrete products but couldn’t find a builder and structural engineer to work with them for a reasonable amount. I did find a similar product though.. the Eterna blocks. A local engineering firm has worked with them before and has a concrete person who builds exclusively with the blocks. I’ve gotten the bid in for 2×6 R19 construction from all three builders. I’ve gotten 1 bid in for the block system and hoping for another early this week. From talking to the engineer and concrete person, the pricing is somewhat competitive so I’m interested to see what it really comes out to. None of the builders seem too interested to work with them (mostly because they are unfamiliar) but I like them for a couple of reasons.. Insulation (for heating/cooling reasons and sound), they don’t really burn, resistance to termites, and ease of applying stucco. The big downsides are cost, lack of options for people who work with it, and lack of general information available.

Hopefully there will be more news coming soon!
