We’ve already listed Rocio Romero’s LV prefab homes among our 5 favorite eco homes and now they’ve gone and created more options for designing your own cost effective green domicile with the introduction of their LV2 line.

The LV2 is a two story add-on that allows you to stack LV Series, (LVS single story) units.  You can now stack any LVS unit on top of any other to create your own custom home.  LV add-ons are custom connections between LVS units, therefore you will need to engage Romero’a design staff to integrate the add-ons when you’re expanding your existing LVS home.  The LV2 is exactly the same square feet and pricing as regular LV kit units.  The design employs traditional construction materials and techniques, so, once delivered, any general contractor can build an LV Home.

Single unit LV home kits start around $37,000 for an 1,159 square foot unit — the units can be customized and combined in a wide variety of combination and styles — with roofing, windows and exterior decks/stairs, site work, building lot, etc. not included.  LV units can be delivered almost anywhere, and because of the nature of the on-site construction, qualify for a traditional mortgage.
