Project Description

The clients of Red and White Pines requested a home integrated into the surrounding forest. The clients intend to manage the mature Red and White forest as a retirement plan, and the house is intended to be the central point of this activity, designed using Passive House standards to reduce the house’s energy requirements.

Situated within a clearing of mature red and white pine trees. The house is located to use solar exposure efficiently and allow the coniferous trees to provide winter protection.

It is an ARCA-VERDE desire that all technology within a house has little to no presence. It can be difficult with sustainable ideals, but allowing architecture to be the first response is achievable. Rather than relying on technology or equipment to heat, cool, and ventilate the building shape, interior configuration and window placement are all required. The house shape promotes natural ventilation with low windows that allow air to enter the house and rise to the higher windows on the opposite side of prevailing winds. The east-west long axis with large south-facing windows allows the winter sun to heat the interior, almost eliminating the need for supplemental mechanical heat. This allows adequate natural light in all rooms. Carefully places windows connecting the interior to the exterior, allowing the surrounding tall pines to be part of the house interior.
