	Planning
		The R&D division collects the latest information on dwellings and lifestyles, cooperating with specialists both inside and outside of the company. The division's network includes, among others, universities, planners from the outside, and homemakers.
.
	Development and Designing
		The R&D division uses the information it collects to research just what can be considered a "truly comfortable house". The results of the research are then applied to housing specifications.

	HAPPS: Heim Automated Part Pick-up System
		About 300,000 components are required to manufacture a freely planned house. Systems using AI conduct integrated information control from the ordering of parts through production, inventory, and shipping. HAPPS is the automated part pick-up system, which steadily provides components to the production lines. It leads to high productivity, high quality, and considerable precision.
.
	Delivery of Components
		Components are allocated for each house and supplied to the production line.
.
	Ceiling and Floor Panels
		Automated nailing machines fix plasterboards to ceiling joists.
.
	Assembly
		Frames are assembled into a box-shaped structure by fully automatic spot-welding machines and rustproofing is done at the welded points. The precision of assembled units is ±2mm.
.
	Attaching Exterior Wall Panels
		Exterior wall panels are attached to a box-shaped structure with special riveting machine and gaps between panels are filled with gaskets.
.
	Attaching Partition Walls and Fittings
		Partition walls and fittings are attached according to each customer's plan.
.
	Installation of Facilities
		Most facilities, such as kitchens, baths, and stairs are installed at the factory. We can reduce waste and dust at the site by installing these in advance.
.
	Inspection
		At the end of each process step, a specialist conducts strict quality control inspections of over 250 items such as gaps between walls and squeaking of floors or stairs.
.
	Protection
		Units that pass quality control checks are packed in unit-covers, protective sheets, and waterproof caps.
.
	Shipment
		Units are loaded onto special trucks by large forklifts and shipped out in accordance with the customer's delivery date.
.
	Installation of Units
		Cranes are used to install units onto solid reinforced-concrete bases.
.
	Roofing
		Roofs are also manufactured at the factory and delivered to the site to be installed simultaneously with the units. Completed in a day, interiors are prevented from being exposed to rain or wind.
.
	Interior Finish-Work
		Interior components are also shipped from the factory and interior finish-work is totally carried out under a roof, thereby preventing exposure to rain.
.
	Measurement of Performance (Formaldehyde)
		We sample the air of the completed house to measure the density of formaldehyde (Kitagawa-method Detector). You can see by the low values just how thoroughly we have eliminated formaldehyde.
.
	Hand-over
		The average period of work at a site is 40 days from installation to hand-over - one-third the time of conventional construction methods.
