How can I make my house warmer in winter by remodeling?

Rather than making only one room warm, it is important to eliminate cold spots in the building.
This will prevent heat shock, dampness, and condensation due to temperature differences, and allow you to live comfortably at around 20 degrees Celsius.

Specific renovations that can be done
(If necessary, we will combine the following methods)

1.Thermal insulation retrofitting of window surfaces.

2.Heat insulation retrofitting of exterior wall surfaces, roof surfaces, and foundation surfaces

3.Space inside the building frame (space under the floor, cavity in the inner wall, foot space between the first and second floor, and shed space) is connected so that air flows through it.  ⇒  It brings about the effect of air cycling.

4.A heat-collecting ventilation layer is installed on the roof surface ⇒ Solar heat is captured from the roof surface.

5.Install a heat-collecting ventilation layer on the exterior wall ⇒ Solar heat is captured from the wall surface.

6.Install floor heating.

7.Turn a floor plan full of private rooms into an expansive space.

8.The under-floor space heater “Kakurenbo” provides low-temperature radiant heating for the entire house.

Remodeling the second floor into a large kitchen and living room space with natural materials.
