Green Building That Lowers Bills, Not Comfort
Double Diamond builds very energy-efficient homes, and our homeowners find their energy bills are the envy of their neighbors. Better insulation, efficient HVAC, and upgraded windows go into every home, without giving up any luxury or style.
Green Building Features

LED Lighting

Frequently Asked Questions
We bring the same energy-efficient techniques to every home we build throughout the greater San Antonio, Boerne, New Braunfels and Texas Hill Country areas, including many of the communities we build in today.
We don’t offer “in-house” financing, but we have arrangements with several local lenders who can handle both your construction loan and your permanent financing needs.
As a true custom home builder, we’re happy to accommodate requests for eco-friendly materials, finishes or amenities. Our only requirement is that it’s structurally sound.
We’re a turnkey builder, which means we detail the specifications of all the work in the contract. We typically present the bid as a lump-sum contract in which we take on the risk for theft, price increases, and the like — this becomes your “drive-out” price. We generally include allowances for items such as tile, light fixtures and plumbing so you have a realistic budget to select from after the contract is signed.
An Insulated Concrete Form (ICF) is a hollow block of polystyrene stacked much like Lego blocks, then filled with rebar and concrete. ICF homes can be built in any architectural style and finished out like a wood-framed home, but it’s what you don’t see that makes the difference: they can withstand winds up to 200 mph, carry fire ratings up to 4 hours, reach R-values of R-22 to R-30, and provide energy savings of 50–80%. Double Diamond is an experienced ICF builder.
We offer the most complete warranty package available: a 10-year structural warranty from a third-party provider, two years of coverage on mechanicals, and a one-year warranty on all workmanship after completion.
