Since HJLCMS broke ground on June 1st on the Hansen House, there has been a lot of progress on site. We wanted to make sure that none of the trees were unnecessarily disturbed by the construction process so signs were placed at drip lines of the trees to protect the root systems. The new driveway was engineered to share a portion of the existing driveway to reduce the footprint of new construction. Gravel was used because it is a permeable surface that allows rainwater to be absorbed and therefore naturally filtered. Once the driveway was complete, the crew excavated the area for the house and dug out the footers. The Hansen House is designed as an energy-efficient building. One of the keys to an energy-efficient building is the use of high levels of insulation. The concrete footers and block foundation both contribute to the super insulated slab and insulated slab ledge. Because heat is lost through foundation walls and concrete slabs, it is important to insulate them. There is 2” rigid foam insulation along the perimeter walls of the block foundation. The foundation is part of the house’s thermal envelope. A clear penetrating sealer has been applied on all perimeter walls from the footers to the tops of walls to damp proof the foundation. The insulated foundation contributes to the conservation of energy and heating and cooling costs and also eliminates potential moisture and mold problems.

Introducing the Hansen House – HJLCMS’s newest project. On June 1st HJLCMS broke ground on our newest project in Chester County, PA, the Hansen House. This is one of the several projects HJLCMS has going on during this busy spring and summer. In line with the mission statement of HJLCMS, this project will be built around sustainable systems incorporating the highly energy-efficient green technology standards we at HJLCMS hold ourselves to. In the early stages of planning and siting the Hansen House, HJLCMS and the Owners performed a careful evaluation of the solar access, water resources, vegetation, soils and other important natural areas of the site. The information they gathered helped to guide not only the actual location of the house but also some key design elements of the house. For example, the house is designed to utilize passive solar heating, day lighting and natural cooling. Because of this careful planning, there has been minimal site disturbance and all the topsoil will remain on site to be used later in the construction process.
