Terra Firma is committed to supporting people who want to build exemplary legacy homes and buildings using SIREWALL.

Many of the homes shown here have had significant owner input, either during the design phase, the building phase, or in helping stretch the SIREWALL technology.

One of the great pleasures from working in this field is the range of people we get to work with, and the homes that are the end result of synchronistic values are something to be proud of.
