Work Flow

We value the first hearing in order to reflect the feelings of the owner in the design.
We would like to hear your requests such as questions / anxieties about building a building, and difficult problems that you have given up.
Prepare a rough sketch while organizing and analyzing the request and the information received
Based on this rough sketch, we will continue to study further and summarize the proposal.


We will answer your questions as much as possible.

Family structure, lifestyle, hobbies, required number of rooms, size, storage, heating system

Please tell us about your desired move-in time and financial plan.

If you request a store, in addition to the business plan such as business type, location, budget, target, etc.

Please tell us what kind of store you want to make.

Please prepare a site map / public map. If you do not have it, please contact us]

Field survey

We will investigate the area, equipment status, laws and regulations, surrounding environment, etc.

Please feel free to contact us even if the site / tenant has not been decided.

If you are looking for a site / tenant property, we can give you advice for the site / tenant.

If it is a store, it is also possible to investigate the range that can be visually judged, such as whether the property is suitable for the business type or not, such as the status of equipment.

(If an investigation by a specialist is required, the actual cost will be settled.)

Rough sketch presentation / examination / financial planning

We will present a rough sketch and an estimated cost sheet based on the hearing information and the field survey.

Based on that, we will exchange opinions in more detail and make the image more concrete.

2-4 weeks


Based on the results of the examination so far, we will create materials for the presentation.

We propose the most suitable expression method for each case, such as floor plans, sketches, CG, and models.

Depending on the scale, it will take about 2-4 weeks to prepare because the examination and work will be repeated until you are satisfied.

[We will support you until the first presentation for free]


Design supervision contract

We will consider the presentation proposal for a while, and if you approve the proposal, we will conclude a design supervision contract.

[If you have a design supervision contract, please pay the first design supervision fee (2% of the estimated construction cost)]

2-3 months



basic design

Based on the presentation plan, we will consider planning in more detail.

Change of planning ・ If it is different from the image, we will correct the plan.


[Plan, elevation, cross section, finishing table, etc. will be summarized to finalize the plan]


2-3 months

final design

We will create various implementation drawings based on the basic design drawing.

The drawings will be explained one by one in an easy-to-understand manner.

For finished building materials such as flooring and wall materials, please actually see and touch the sample to check it.

In addition, we will consider the usability together while having you imagine the actual use.


[Create a drawing for the construction company to get a quote]


2-4 weeks


Construction estimate

Request a construction quote from the construction company.

Select the most suitable construction company for each case and submit the implementation design drawing.

Calculate an estimate of the construction cost.

Depending on the situation, it is possible to make an estimate by several construction companies.

The period until the estimate is completed varies depending on the size of the property, etc.

In the case of a store, it takes 1 to 2 weeks, and in the case of a house (new construction), it takes 3 to 4 weeks.


About a month


Estimate adjustment

Because it is difficult for customers to grasp the contents of the building estimate

By checking from a fair standpoint, I can carry out the construction at a reasonable price.

In addition, depending on the situation, it is possible to make an estimate by several construction companies and make a selection after comparison.

If you exceed your budget, review the finished building materials and specifications and adjust the design to fit your budget.


Construction contract

A construction contract will be signed between the customer and the construction company.

Generally, at this stage, the first payment to the construction company will occur.


[Please pay the second design supervision fee (4% of the construction cost) after the construction starts]

[Generally, payment to the construction company is also required]


Design supervision

Construction will finally start.

We will visit the site on a regular basis and supervise whether the construction is properly carried out based on the drawings.

If something goes wrong, we will discuss closely with the construction company and make adjustments so that the construction will proceed smoothly.

In the unlikely event that there is a defective construction, it is difficult to detect it after completion.

It can also be prevented by performing design supervision.



After the construction is completed, it will be handed over after inspection in the presence of the customer.

Inspect whether it is completed according to the drawing and whether there are any functional defects.

If there are any deficiencies, we will fix them everywhere.

In addition, we will receive handling instructions for equipment, etc. from the construction company.


[Please pay the third design supervision fee (4% of the construction cost) after the delivery is completed. * Final design supervision fee]

[Generally, payment to the construction company is also required]


Inspection after delivery

The construction company and our office will carry out regular inspections in one or two years.


[If a problem occurs immediately after delivery, we will work with the construction company at any time]
