Historical Carriage House
Proposed Front Elevation
Contrasting the proposed elevation against the existing structure you can see the major architectural features of the Carriage House remain dominant. The eyebrow roof line while broken is done so purposefully to accent each entry to the residence as an individual feature, yet incorporating a continuous architectural concept throughout the elevation. The increase in depth features both form and function. By increasing the depth the roof serves as a protective overhang from weather when entering and exiting the building yet allows the introduction of columns and corbels to accent the structure and add period charm. The removal of the shingle sidewall, a deviation from the original architecture, enables the restoration of the traditional clapboard siding to match the main estate house.
Proposed Side Elevation
The side elevation features the inclusion of additional period architecture. The combination of a double door set with divided lites over a single wood panel and the introduction of oval windows, a predominant architectural feature of the era, provide articulation to an otherwise bland elevation.
While maintaining the appearance of traditional Victorian architecture both inside and out providing functionality and comfort throughout was paramount. By incorporating design concepts which feature modern day amenities placed discretely Geurse Conceptual Designs, Inc. achieves the desired effect of both comfort and design. Examples include direct gas fireplace to provide both comfort and period architecture, window seat features throughout the second floor which provide hidden duct chases to allow for the full use of volume ceilings on the first floor while providing air temperature control throughout the structure, exposing the second floor cupola to the interior allowing natural light and ventilation to permeate the second floor and many other features to numerous to list here.
Demolition of all the interior finishes, drywall, cabinetry, plumbing, electrical, mechanical and the existing slab floor and foundation are necessary to facilitate the renovation of the structure. Once removed the structure is prepared to be raised off the existing foundation to a height of four feet to allow for the installation of a new seismically engineered foundation.
Once the necessary demolition and preparation has been completed ledger boards are fastened mechanically to the structure’s perimeter walls. From that point heavy steel I beams which span the entire length of the structure are placed below the ledgers. Six hydraulic jacks capable of lifting forty tons apiece simultaneously raise the support beams lifting the structure off the existing foundation. Once the desired height is achieved the support cribs are placed below the I beams and the jacks are removed.
Once the structure is secure the installation of the new foundation & slab can take place. A two stage process, the perimeter must be placed first, allowing the structure to be lowered into place. Once securely anchored to the foundation the support cribs are removed and the center slab can be prepared. The plumbing and mechanical is installed then the structural rebar is placed. Insuring a strong and stable foundation.
The challenges of working with a structure over one hundred and twenty years old are myriad. The walls, floors, and roof structure all need to be straightened, plumbed, and leveled to allow for modern finishes while at the same time facilitating upgrades for modern amenities such as computer networks, low voltage lighting, high efficiency heating and appliances. While all the amenities of modern living are desired incorporating these items while meeting current building codes further increases the challenge.
Once the building has been lowered onto the foundation the walls are straightened and the floors raised to alleviate problems associated with settling and age. Installation of seismic hardware and a new structural plywood diaphragm ensure safety in the event of earthquake as well as prevent any future regression. New energy compliant windows that reflect the period architecture are installed to accent the exterior. Prior to the installation of siding a breathable moisture barrier is placed to ensure a weather tight shell. Finally the installation of clapboard siding prepared with six coats of primer and fastened with stainless steel nails begins the final phase of the exterior.
