The budget for construction is a very important condition. We try to pay the client's request within the desired cost, regardless of whether the budget is large or small, by scrutinizing the client's demands and creating smart architectures without being bound by existing concepts.

Based on the proposal, we will conclude a design supervision contract when we are satisfied with the architectural outline.
At this stage, 1/3 of the design fee will be charged as the start-up fee.

While making a meeting based on the proposal, we will create a basic design drawing, CG, model, etc., examine the plan, select materials, examine the equipment and structure, and determine the outline of the architecture.
Step5 Implementation design
Make a detailed drawing by making a detailed meeting.
Step6 Contractor's estimate and administration application
Assess the estimate (adjustment work to make it an appropriate amount). Create a reduction plan as needed and adjust with your budget. After confirming the construction amount, apply for confirmation.
At this stage, we will charge 1/3 of the design fee as an intermediate deposit.
Step7 Construction site supervision
Once construction begins, we will conduct on-site supervision to confirm that construction is being carried out according to the design document. In addition, we will inspect with structural specialists according to the stage.
