Meticulously designed, modeled, and constructed, the Kala home at 4800 State Line is unlike any other in the area.
Taking the definition of luxury to a new level, you’ll feel the difference quality, high performance construction makes as soon as you enter the space. Built to Passive House standards, the home is virtually airtight, has a continuous air barrier and uses an ERV for mechanically controlled fresh filtered air.
We are excited to collaborate with
ULAH Interiors + Design for the interiors of the State Line Passive House.

It's All in The Details
Air-tight (0.064 CFM50/ft2), vapor-open envelope assembly
To ensure the durability of the house, it's important that it doesn't leak air in or out during the summer and winter months, and that any moisture is able to dry outside.
Thermally-broken, triple-pane, NFRC certified U-Value of 0.14 windows
Highest performing windows in the world: keeping the house cool in the summer and warm in the winter without sacrificing natural light.
Custom-built high-performance entry door with multi-point locks with U-Value of 0.14
Exceptionally durable doors that are airtight upon closure.
R-45 wall assembly
Exceptional insulation capacity for managing thermal transfer of energy.
R-71 roof insulation
The ultimate thermal control layer in both winter and summer, keeping the house a comfortable temperature year round.
R-18.4 continuous slab and foundation insulation
Exceptional insulation capacity for managing thermal transfer of energy and helping the slab maintain a steady temperature relative to indoor temperature.
Mechanically controlled continuously filtered fresh air system
Ensure air that is EPA IAQ+ Certified, meaning exceptionally clean air.
Heat pump hot water heater
Ultra efficient hot water source for entire home.
12.6 HSPF heating and 17.8 SEER cooling high efficiency heat pump
Coupled with the control layers, ensures energy costs are 80-90% lower than a similarly sized conventionally built home.
Duct leakage of 18 CFM @ 25Pa
Staggeringly low duct leakage ensures that the HVAC system works seamlessly, requiring very little energy.
Whole house dehumidifier integrated into duct work
Manages humidity for the entire distribution network ensuring moisture consistency throughout entire home.
Minimized thermal bridge design
Lowering energy required to heat and cool the house and eliminating potential for condensation in the wall system.
Installed EV charging
Ability to charge your electric vehicle in the garage.
Solar ready
Full electrical plumbing infrastructure in place for easy addition of solar panels.
