With deep local knowledge and a passion for thoughtful design, we help Allyn homeowners bring their
ADU dreams to life—seamlessly and beautifully. Welcome to LM Stevens Designs, your architectural
home base in Allyn, Washington! You’ve likely heard about the buzz surrounding accessory dwelling
units (ADUs)—and for good reason. Whether you’re dreaming of a modern ADU design, luxury kitchen
interiors, or a sleek custom home, we’re here to guide you from concept to completion.
Why ADUs Are All the Rage in Allyn & Beyond
Washington state has changed its ADU laws in recent years, permitting units of 1,000 square feet or
more, eliminating owner-occupancy restrictions, and permitting up to two ADUs per lot. That includes
garage ADU designs, basement conversions, or stand-alone backyard cottages—nicknamed DADUs
(detached ADUs). Cities like Seattle have seen ADU permits rise over 30% year-over-year (Axios).
Homeowners are now embracing energy-efficient layouts, online architectural sessions, and 3D
walkthroughs to bring their ADU plans to life. These sessions often help visualize modern bathroom
ideas, kitchen remodel goals, and minimalist living space concepts.

Embracing Washington’s Hottest ADU Trends
Recent trends in Washington feature open layout ADU design, seamless indoor-outdoor living, and eco-
friendly materials and energy-efficient home design. These trends often incorporate open kitchen
concepts, living room interior inspiration, and space-saving bathroom design. Multifunctional areas with
Murphy beds, foldable furniture, and integrated home offices are crucial for small-scale luxury. Climate
systems, energy controls, and voice-activated lighting are a few instances of the ubiquitous integration
of smart technology. When you add a lovely patio or deck off the kitchen, your modern ADU seems
spacious, cozy, and linked to nature.
