Let's build homes where everyone is the protagonist. Kenchiku Ichiba dreams of realizing a "market where everything in architecture is connected."

Our company endorses April Dream, which aims to make April 1st a day for announcing dreams. This press release is a dream of "Kenchiku Ichiba Co., Ltd."

Kenchiku Ichiba Co., Ltd. (Headquarters: Toshima-ku, Tokyo; Representative Director: Tomohiro Amano; hereinafter "Kenchiku Ichiba"), which operates "Kenchiku Ichiba," a custom-built home DX platform that directly connects homeowners, architects, and craftsmen through direct ordering, will realize a marketplace where all people involved in architecture can connect and create a new paradigm for the custom-built home industry.

"Someday, I want to build a home that truly reflects us."

Despite this wish, the number of families in Japan who have given up on this dream is increasing.

Soaring material costs, rising labor expenses, and multiple layers of intermediate margins—custom-built homes are becoming "something only for a privileged few." Kenchiku Ichiba Co., Ltd. exists to change this reality.

Our dream is to make home building "free, fair, and satisfying for everyone." And to create the ultimate architectural marketplace where all things, events, and know-how related to architecture actively circulate.

The living environment is undergoing significant changes—this is the current reality in Japan.

People are losing the ability to be particular about their lifestyles.

Starting with rising land prices, material costs, labor costs, and the industry's multi-layered subcontracting structure, estimates for homeowners wishing to build a house continue to swell opaquely. Furthermore, choices for building materials and equipment are limited to catalogs, and specific preferences for living are dismissed as "cost issues."

As a result, people are forced into situations where they cannot realize their ideal homes and lifestyles, leading to regret. According to a survey on "Regrets of Custom Home Buyers" conducted by our company in September 2025, many buyers cited important equipment and performance for their homes that they had to give up due to budget constraints, despite truly wanting them.

Meanwhile, architects and craftsmen, under the pressure of excessive intermediate costs, cannot receive fair compensation and are even losing the capacity to pass on their skills. This is a crisis directly linked to the decline of the entire industry. Especially among craftsmen, over 80% do not wish to recommend their profession (craftsman) to others.

"A society where everyone can own their home"—that natural dream is quietly crumbling now.

Our Dream and What We Can Do Now—Democratizing Home Building

Kenchiku Ichiba Co., Ltd. operates an online platform that directly connects homeowners, architects, and craftsmen. The concept of "direct ordering" has existed in the construction industry for a long time but has not been widely adopted. Complex process management, the barrier of specialized knowledge, and the assurance of trust—these challenges made direct ordering "for experts only." We are changing that. By combining deep architectural knowledge with digital technology, we are building an environment where anyone can build a home with peace of mind and freedom.

"Sanpo Yoshi" Home Building Realized by Kenchiku Ichiba

• Homeowners: Transparent price breakdowns and true freedom to build with their own specifications

• Architects: Fair compensation and the restoration of the joy of designing together with homeowners

• Craftsmen: Fair compensation without intermediate exploitation and an environment where skills are properly evaluated

"Building a home, together we grow it."—This is the vision we are practicing today.

April Dream—Towards a Market Where Everything in Architecture is Connected

Our dream is not limited to a custom-built home platform.

Kenchiku Ichiba's goal for the "Ultimate Marketplace":

• 【Transaction of Goods】Direct transaction platform for housing equipment and interior furnishings—a market where consumers and manufacturers/sellers connect directly without intermediaries

• 【Transaction of Tools】Transaction market for design tools and equipment used by architects and craftsmen—a place where professionals can obtain truly necessary items at fair prices

• 【Transaction of Know-how】Transaction market for "skills and know-how (software)" necessary for the succession of craftsmen's techniques—a system where the techniques of master craftsmen are passed on to the next generation of craftsmen

When this ecosystem, where both hardware and software are organically connected, is completed, a world will emerge where everyone involved in architecture can "face home building with satisfaction."

This is not merely business expansion. It is about creating a social infrastructure to protect Japan's architectural culture and the skills of architects and craftsmen, which are on the verge of being lost, and to pass them on to the next generation.

The name "Kenchiku Ichiba" (Architectural Market) is our dream itself.

A market (marketplace) for everything related to architecture—we are seriously committed to creating the future that this name literally signifies.
