Method is divided into 3 simple steps

1. Purpose the keys concept as described in 4 phrases. They were “to be in woods”, “to live well and safe”, “to be flexible and convenient” and “to be energy concern”.

2. Develop the architectural design based on the concepts.

3. Adjust the design followed their comments until their satisfaction and reasonableness for all conditions concerned. 

4. Propose architectural style that is neutral and suit for everyone. 

Before, process design, the 4 phrases were interpreted to architectural design techniques or criteria. They were described below 

– “To be in woods” this phrase summarized core idea of biophilia(Kellert, 2015). Therefore, architectlocatedmajor building inaproperplaceandsurround bytrees, plants and waterto make the building most connects to the natural environments. 

– “To live well and safe” this idea combined universal design (“Universal Design,” 2021)and some of wellbeing approach(“Design for Well-Being,” 2021). So the design were focused on universal design, psychological and physical safety, health concerned approach such as no niches, no or very less steps, add space for art pieces, no hazard materials and no blind spots etc. (Sreshthaputra et al., 2021). 

– To be flexible and convenient is to design with open plan (“7 Reasons Why to Use an Open Floor Plan in Your Home Design,” 2021) which is easy to adjust or replan later to suit the future needs, easy to maintenance and to add house elevators for convenient and suit for users’ ages. 

– To be energy concerns is to design with good natural light and ventilation using less machines, to use a proper heat prevention means, to design proper room height, and to prepare area for install solar power system. 

To design properly, their activities or some important issues were considered in design proposal. Grandma had no specific need but due to her age, architect prepared her area on 1st floor with universal design criteria, large space for future attendant or adjustment, private bathroom, living area and pantry for her convenience and future need. Her son and his wife wanted separate bedrooms, so architect designed 2 bedrooms with studio type functions such as bed area, working area and private bathroom with large closet. On the other hand, his son wanted to have his own living space, so architect provided his room bigger than others. Her daughter and nephew had no specific requirements, except in the interior style, therefore, architect also proposed studio type style with full functions to them. Additionally, architect designed all rooms using movable furniture rather than built-in so, the rooms could be adjusted to suit their future needs effortlessly.

Besides, their private compartments, architect prepared the large open plan living, dinning and pantry area in the middle of 2nd floor as embodiment and party area. All furniture in this area were movable to suit any events occurring.

Due to the mix of their age, architect suggested the house in the simplicity style by very clean aluminum composite box like which they all agreed. The building is located near the big pond facing the south-east and surrounded by garden. So, architect designed the big glass window covered with long canopy to prevent direct sunlight but enjoy very precious view which emphasized the design concept also.
