OUR POSITION

— The Process

From series
to keys in hand.

Four moves, three to five months. No surprises. No site coordination headaches. The system runs the build — you choose, configure, secure, move in.

01

Choose

Select a Tokyo Series variant — Shiro, Muji, Aman, Mid Century, or Concrete. Or commission a custom brief.

02

Configure

Walk through finishes and options at the IDD showroom or on a video consult. Lock the design in two visits.

03

Secure

Sign the build contract — 20% to begin manufacture. KPR Konstruksi accepted on partnered banks.

04

Move in

Three to five months from contract to keys. We hand over with the MORI quality mark and a 5-year structural warranty.

— The Quality Mark

MORI
— the system

MORI (森) — a gathering of trees forming a forest. An ecosystem in balance. Like Daiwa House or Sekisui in Japan, every home Accossa builds carries the MORI mark: a Japan-grade supply chain, an engineered LGSF frame, and a single accountable builder — no matter which architect designed the house.
