Launch of 'erabitte', a Smartphone-Based Fixed-Price Custom Home Service Designed by Women Architects

News Overview Sumarch Co., Ltd., which operates a custom home business in Aichi Prefecture, launched 'erabitte' in May 2026, a new custom home product featuring a transparent fixed-price model and custom-made furniture. Based on the concept of 'delivering time and peace of mind to busy mothers,' the service merges the sensibilities of female staff with a smart, smartphone-complete home-building process.

Development Background In response to feedback from dual-income families struggling with limited time for meetings, budget overruns, and the burden of complex specification decisions, a team of female architects and interior coordinators at the company developed this product. By introducing a cloud service that allows users to make selections anytime via smartphone, the company has significantly reduced the burden of building a home.

Four Key Features of 'erabitte' 1. 'Mother-perspective' design by a professional female team: Proposes stress-free floor plans tailored to household flow and childcare. 2. Four curated design styles: Users can choose from four trend-focused styles: Japandi, Natural, Feminine, and American. 3. Fun smartphone selections with 'egaku': Allows for 24/7 specification checking and instant price estimates, making home building easier and more intuitive. 4. Secure fixed-price system: Prices are determined by the floor area (tsubo), allowing customers to pursue their ideals without worrying about budget overruns.
