Here, it is assumed that an input is made to collectively change the flooring material of the Western-style room to the flooring material B. That is, the floor material B is input to the floor material (Western room), and all other items are blanked.

Subsequently, when the change button displayed at the lower right of the batch change information input screen is pressed via the input device 40, the batch change process of the design content is executed. As a result, the building materials constituting the building corresponding to each design information are collectively changed to the specified materials. Here, as shown in FIG. 11, the flooring material of each Western-style room, living room, dining room, and kitchen is changed from the flooring material A to the flooring material B. Other design information is also changed to floor material B when a floor material other than floor material B is used.

It should be noted that the design information after the batch change can be collectively changed to another building material or returned to the design information before the change. Further, when the batch change is performed again, the changed design information may be overwritten with the design information before the change (the batch change was made immediately before) and registered, or may be registered separately. .. In addition, design information with the same material before and after the change is not changed. In this case, it may be excluded from the re-search target without being registered in the changed design information management table 440, or it may be registered in the changed design information management table 440 and left as a re-search target.

Next, the process proceeds to step S218, and the construction cost of the building corresponding to the design information after the batch change is recalculated based on the price information of the material after the batch change registered in the price information table 460. After that, the process proceeds to step S220. For example, in the example of FIG. 11, the construction cost has increased from 35 million yen to 30 million yen because the floor material A has been changed to the floor material B. That is, this design information will remain as a candidate when the owner's budget is 30 million yen.

In step S220, the building specification information, the building cost information, and the design information after the batch change are registered in the changed design information management table 440 in association with the building specification information, the building cost information, and the design information before the change. After that, the process proceeds to step S212. Here, the building specification information includes building materials such as flooring materials, wall materials, and fittings used for construction as other specifications, and these materials are changed to the changed materials.

On the other hand, when the design change is not proposed or the process proceeds to step S222 without making the design change, the narrowing-down result display screen shown in FIG. 7B is displayed on the display device 44 as in the first embodiment. The decision of the design information to be used is requested, and the decision button displayed on the right side of the detail button of the display name of the desired design information is pressed via the input device 40. As a result, the design information to be used for generating the design document is determined from the design information candidates displayed as the narrowing down result.

Then, when the process proceeds to step S224, a design document is generated based on the design information determined in step S222. After that, a series of processes is completed.
[Effect of the second embodiment]
Next, the effect of the second embodiment will be described.

Is specified so that it can be changed to the specified design contents at once. In addition, based on the price information in the price information table 460, the building cost of the building corresponding to the design information after the batch change is recalculated, and the building specification information, the building cost information and the design information after the batch change are changed. It is now registered in the changed design information management table 440 in association with the previous building specification information, building cost information and design information. Further, the design information below the budget entered on the budget information input screen is searched from the changed design information management table 440 in which the information after the batch change is registered.

With such a configuration, for example, if a lot of design information of the design that meets the owner's request is searched for, but the budget is exceeded in all cases, the building corresponding to these design information It is possible to lower the grade of materials used for construction at once and perform a re-search. This makes it easier to obtain design information that generally satisfies the client's request within the budget.
