High Performance Meets High Design

SixTwentyOne, Kali Buchanan Design, and Kala have joined forces to craft a home that showcases the essence of natural light, timeless design, and a seamless blend of indoor-outdoor living. This home was designed around a slit of daylight through the center of the home, allowing natural light to pour deep into the interior. Design elements like this coupled with high-performance details are truly redefining luxury.

It's all in the details.

Every Kala home is designed and built to meet a higher standard. This new build in Westwood was no different - crafted to provide exceptional comfort, health, durability, and sustainability for decades longer than a traditionally built home.


The difference goes far beyond aesthetics; it’s intentionally included in every layer and detail, from the continuous exterior insulation in the airtight building envelope, to Phius-certified windows and doors with thermally-broken frames from Alpen, to an ERV system that provides whisper-quiet mechanical ventilation. 

  • Airtight (target below 1 ACH50*), vapor-open envelope assembly

    Keeps your home comfortable year-round by preventing air leaks while allowing any trapped moisture to dry safely outside, ensuring long-term durability.

  • Thermally-broken, triple-pane, NFRC-certified U-Value of 0.14 windows

    Among the best in the world, these windows provide exceptional insulation while allowing for abundant natural light—keeping you warm in winter and cool in summer.

  • Custom-built high-performance entry door with multi-point locks, U-Value of 0.09 on door glazing

    Multi-point locks and airtight seals make these doors not only secure but also energy efficient and incredibly durable.

  • R-30 thermally-broken wall assembly

    Exceptional insulation capacity for managing thermal transfer of energy.


  • R-16 continuous slab and R-26 foundation insulation

    Minimizes thermal energy transfer and helps the slab maintain a steady temperature relative to indoor temperature.


  • Mechanically-controlled, continuously filtered fresh air system

    Delivers exceptionally clean air certified by the EPA’s Indoor Air Quality+ standards, ensuring a healthier living environment.

  • Hybrid hot water heater

    An ultra-efficient hot water solution that’s as sustainable as it is effective.

  • 10 HSPF heating and 17 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.


  • Minimized thermal bridge design

    Reduces energy loss, prevents condensation in walls, and ensures consistent indoor temperatures.

  • EV charge ready

    Conveniently charge your electric vehicle in your own garage.
