Location house (Utbuorren 2A Winsum)

Surroundings1. The project2. Surroundings3. The house Drawings4. Survey Adjustments/





The house Owner house: Mr. Roest Location: Winsum Year build: Feb. 1976 Semi detached house 4 bedrooms Private drive way and garage Front and backyard Heated by means of pallet stove






Drawings1. The project2. Surroundings3. The house Drawings

4. Survey Adjustments/





Survey(defects)

Rear window frames Window sills are rotten and loose






Survey(defects)

Joints on the west side have fallen out.






Survey(defects)

Fascias (roof boards) Are rotten






Adjustments/ImprovementsWhat Why

Scullery demolition To make space for the conservatory.

New window frames Most of the window frames are rotten.

New Fascias (roof boards) Fascias on the south side are rotten.

New Joints The joints on the west side are falling out.

New sun room To create more living space.

New carport Mr. Roest can keep his car dry.

New window sills Some of the window sills are loose.

Painting dormer So the wood doesn’t rot.

7. Conclusion 8. Questions

Conclusion RC-values of the floor, roof and the exterior wall don’t all

meet the recent requirements, so we improved it: The roof went from 2,225 to 5,942 The ground floor went from 0,159 to 3,904 The exterior wall went from 0,5 to 4,519.
