Double R 2.0, also known as "Mouse House", is a renovation project that aimed to transform a previously neglected property into a comfortable and energy-efficient home while preserving the original structure's character. The house had been subjected to a few rogue remodeling projects over the years, and the organic alfalfa growing outside had attracted a growing population of mice. However, news of an incoming baby prompted a complete overhaul of the house. The renovation involved stripping the house down to its studs, expanding the square footage, and adding a garage to improve functionality. Additionally, the team reclaimed and repurposed components of the original home to maintain its authenticity. Furthermore, energy performance was boosted to enhance the overall comfort and sustainability of the house.
