Planning & Proposal Expertise
While fully custom-designed homes offer the joy of creating from scratch, they also require considerable time and often bring many challenges due to the high degree of freedom.
For this reason, KAⅡ provides homes planned based on professional knowledge and extensive experience.
3 Core Concepts
Clean & Simple Plan
The Core of High Design Quality
The “Clean & Simple Plan,” composed of smooth rectangular forms, straight lines, and vertical elements without unnecessary irregularities, represents the foundation of residential design.
The three-dimensional spaces created from the “Clean & Simple Plan” generate refined, highly designed living environments—qualities that cannot be achieved through irregular or fragmented planning approaches.

Kajiraku Plan
Reducing Household Workload Through Spatial Design
The “Kajiraku Plan” is designed to reduce the burden of household tasks through thoughtful spatial planning.
By connecting the utility room seamlessly with the kitchen and laundry area, household movement is streamlined, minimizing unnecessary steps and reducing the daily workload of housework.

Kodawari Plan
Add +α value with a space that reflects your personal style.
We have prepared the “Days of the Week” series, developed in collaboration with architects.
Seven plans—Sunday through Saturday—have been carefully designed.
Each plan is a home that brings your ideal lifestyle and personal preferences to life.


A home designed to enrich daytime living, where mothers can enjoy time spent on childcare and with friends.


A home that enhances nighttime living, allowing you to relax and enjoy your personal time after work.


A home where you can focus on ingredients and tableware, cook with passion in a carefully designed kitchen, and entertain guests with pride.


A home where you can fully enjoy bath time—day or night—by soaking in warm water or stepping outside to relax at your own pace.


A home with a dedicated workshop and large tool storage, where you can enjoy DIY projects such as home improvement and furniture making.


A home for gathering friends, hosting home parties, and enjoying time with your favorite cars.


A gardening home with earthen floors, where you can grow plants both indoors and outdoors and live surrounded by greenery.
