In continuation with the great room, I thought that it would be best to cover the loft area next. The loft consists of a sitting area and a balcony through which the chimney extends up through. The custom fireplace and chimney, made with stone found around the property, was built by Stonescapes Inc. of Hockessin, DE. The intersection of the chimney through the balcony creates a lovely, small sitting area that is a perfect spot to read a book. The loft also has a larger seating area located above the kitchen. The railings and balusters were hand forged by Harris Metalsmith Studio LLC and are simple twisted picket design, painted Satin Black with an Oak cap rail. The floors in the loft are Wormy Maple. Above the sitting are in the loft is a cupola. The cupola assists in passive ventilation.
After the tar paper was installed on the exterior of the Hansen House, the next step was to install the venting network for the siding. Venting behind siding is necessary to prevent the major problems that could arise from trapped moisture. The venting material is cor-a-vent sturdi-strip which runs vertically and cor-a-vent SV-3 which runs horizontally along the exterior of the walls. The sturdi-strips and SV-3 are crush resistant extruded polypropylene core with fluted airways that provide maximum airflow. The SV-3 has an enhanced insect screen to prevent insects from getting in behind the siding. The siding is the HZ5 product line of HardiPlank. The HZ5 products are a special substrate composition designed to perform in climates with freezing temperatures, seasonal temperature variations, snow and ice. Timber bark is the color of the siding with arctic white trim and soffits. The Hansen House has 3 variations to the exterior which give it a unique look. As you approach the house you encounter the stone wall which is a continuation of the original and existing architecture of the farm. When you walk around the to the front the stone fades away to classic siding. This continues along to the side porch. Once you get to the back and side of the garage, the siding makes the final transformation into vertical board and batten. The soffit and trim are HZ5 product line in arctic white. The cupola, where the whole-house fan will be installed to exhaust hot air from the house and for air circulation, has the same siding, soffit and trim as the rest of the house. The main roof of the Hansen House is shingled while the porches and overhangs have standing seam metal roofs.
White PVC pipes run under the slab where the domestic hot and cold running water tubes are housed and run. These plumbing tubes are part of the Hansen House’s wet wall, a structural wall designed to house plumbing pipes for fixtures like sinks, dishwashers, washing machines and toilets. The tubes are connected into the manifold and then distributed throughout the house to the designated fixture. Consolidating plumbing in a single wall increases efficiency as well as cutting down on building costs. The black PEX tubes are for the radiant floor heat which also run to the manifold where the water will be heated by an electric water heater. The PEX tubing was attached to the rebar which was laid out in a checkerboard pattern on top of the foundation’s 4″ of insulation. Then concrete was poured to form the slab. The kitchen island location and outline were marked by tape on the floor for reference points. After the plumbing tubes were all in place, the cellulose insulation could be sprayed. Netting was installed on ceilings and walls to hold the blown in cellulose in place. The netting was used so that the drywall would not have to be installed before the insulation was blown in, which could cause moisture problems. The windows and doors were covered with plastic to be protected during the spray insulation process. Polyurethane, the yellowish material, was sprayed to seal any plywood seams to ensure a tight building envelope. Because the insulation is blown in an excess of material tends to accumulate; therefore, while one person blows in the cellulose another person vacuums it up where it is sent back to the truck and recycled back through the process. The metal braces seen in the picture below are part of the t-bracing which prevents lateral movement. Rigid foam was added to the cavity so that settling of the insulation was minimized and controlled.
HJLCMS has been very busy finishing up the KSQ Barn/Carriage Shed. The last update ended with the exterior being prepared for the siding and the installation of the standing seam metal roof. However, before the siding could go on, the windows had to be installed and the electric had to be run. Once the windows were in and the electric had been run, the siding could be installed. The material for the exterior finish is rough sawn board and batten for the first story and a cedar shake for the second story, upper gables and cupola. While this was going on, one of the HLTF crew members was building the cupola in our shop. The cupola was then transported to the job site where it was finished with cedar shakes and standing seam metal roofing. This cupola is not solely ornamental, as it will function as passive climate control as well as house the ventilating fan. The cupola was then flown into place with the crane. Check back for the next update.
