Construction Cost Indication

We have no generic plans for building houses. Instead, we usually offer the estimated price of the specific construction cost for each customer. We first listen to the request from the customer, and then, design the house and decide on the building plan. After that, we offer the estimated price to the customer. This procedure is always the same for us, even if the request comes through the designer.

Construction cost
affecting factors

  1. POINT1

    House size

    The smaller the construction area, the higher the unit price. On the contrary, the larger the construction area, the lower the unit price. One of the reasons is that equipments such as a kitchen and a bath will cost the same, regardless of the size of the house. Another reason is that even if the floor area becomes narrower, the wall area does not decrease much.

  2. POINT2

    Grade of materials
    and equipment to be used

    If the materials used are expensive, construction costs will naturally increase. In particular, the grade of wood is not largely influenced to the amount, except for building a “sukiya” architecture. In the first place we do not suggest a low grade wood. Approximately 15% to 20% of construction cost is an indication of wood cost.

  3. POINT3

    Building site
    qualification

    Depending on the situation of the building site and the circumstances of the surrounding transportation condition, additional work may be required, and the material loading to the site may become expensive. Especially, if the building site is on a weak ground, the ground improvement and pile driving construction should be needed. In addition, it is very influential in construction costs whether there is water supply or gas retraction or not.

  4. POINT4

    Furniture

    In case the customer purchases ready-made furniture, the furniture price will, of course, not be added to our construction cost. When we are asked to make built-in furniture, the making cost will be included in the construction cost. The built-in storages in the kitchen and a shoes box are usually asked us to make. We occasionally receive a request for making a dining table or a PC desk.

  5. POINT5

    Wooden fixture

    We recommend the customer to build wooden fixture for all inside the house, and for the entrance and sweep windows of the living room. The construction cost will depend upon whether you use wooden fixture or aluminum sash. In addition, the number of fixtures to build, such as building inner shoji inside a window, also greatly affects construction costs.

  6. POINT6

    Earth wall

    Earth walls are constructed in most houses built by us. In addition, you may also choose the “Itakura” construction method. The “Itakura” construction method has the merit of being able to reduce the construction cost more than the earth wall style.

If you keep in mind the above as a guide, it will be a criterion for estimating the construction cost. In case the construction estimate is higher than your budget, please do not hesitate to consult us. We recommend not reducing the construction budget, but reducing the construction area.
