The simple form of the house is sited and designed so that every important living space has south sun exposure, providing solar gains during peak sun hours.
The largely open plan allows for light sharing and cross ventilation of the space for heating and cooling. A large exterior balcony takes advantage of Western views to the mountains and a long continuous exterior stair and garden space connects the garage and house, also forming a view corridor to the west. The main floor is designed for the homeowners and the lower walk out for their guests.
The heating and ventilation system consists of a high efficiency energy recovery ventilator (ERV) and electric resistance heaters with a hybrid heat pump water heater. The mechanical system compliments the super-insulated, airtight envelope of the home and offers summer free-cooling. The house will use approximately 85 percent less energy for heating and cooling compared to typical construction and will approach net zero energy use with the addition of a solar PV array. Approximately 1/3 of the space heating energy is provided by the south facing windows, 1/3 from internal heat gains such as appliances and 1/3 from the heating system. The home design meets the Passive House Institute low energy requirements although certification is not sought.
The home is designed for 0% overheating but has rough ins for exterior operable shutters on the south window as a contingency for future climate warming and change. A 2” concrete topping on the main floor provides a thermal mass to collect solar gains in the day and releases the heat as the air cools off at night. Low embodied carbon blown cellulose is used for insulation in the attic and deep double stud walls. The roof is a standing seam concealed fastener metal roof so that water collected in cisterns around the home is not contaminated by toxins that may be in asphalt or wood. Fiber cement siding is used for fire resistance and durability. Passive house rated frames and triple pane glass windows are used for cost and durability. The surrounding site will be designed and planted around permaculture principals.

This banquette was designed and constructed from 2, 13’-0” long, recycled church pews. The solid oak pews were cut and reconstructed to perfectly fit the space in an L formation.
The bench allows for more people to sit in a small area and gives the space some flexibility of use . People love to spend time here and it provides the perfect seating arrangement for social occasions.
The restored stained glass window is from a 1911 home in Southwestern Ontario.
A 2000 sq ft Renovation to an existing Cabin near Calgary. The view shown is a Courtyard with Western views to the mountain range beyond. This Renovation proposal is to accommodate a retired couple and their extended family.
Renovations focused on the Narthex, Parish Hall and new entry for the Early Childhood Education Center of Christ Church Anglican Parish in Calgary AB.
The new Narthex space was designed specifically to accommodate a flexible program for meetings and social activities as well as provide new Prayer Rooms for the Parishioners. Movable glazed wooden screens were designed to separate the existing Nave and Narthex and also to accomodate flexibility for seating larger or smaller services. A new Entry Vestibule and refurbished Parish Hall provide an entry to the Early Childhood Education Center.
LVD executed this work in support of and in collaboration with Exhedra Architecture and Urban Planning.

The goal of the lady chapel Renovation was to open up the space for greater flexibility of movement, update the layout to current liturgical practice, and modernize wiring. The new design has restored or modified the old finishes, religious fixtures as well as the wiring and floorplan. The original millwork and seating has been carefully updated and integrated to give the space a continuous flow and more room for the small services and prayer the chapel is meant for. The new tile around the altar accentuates the striking blue hue of the Reredos drapery, the wall panels, as well as the Nativity and Holman Hunt stained glass windows that distinguish the chapel as distinct sacred space within the church itself. The more spacious and simplified plan remains true to the original function of the space, while expanding and supporting it’s use for today’s liturgies.
"Passive House" refers to a performance based building standard that may provide up to 90% savings in space heating and space cooling energy. Passive design includes heat gains by passive sources such as sunlight, appliances and occupants and the drastic reduction of required heat allows for a 75% smaller design size of overall primary energy systems. This conservation of energy is achieved by integrated design of energy efficient building components/techniques such as: a super insulated airtight building envelope; minimal thermal bridging and exceptionally high performance windows.
This new home and secondary suite were designed to meet “Passive House” standards. The small footprint allows space for an "Urban food forest" in the front of the home and a large vegetable garden in the rear south facing yard. The simple form of the home, combined with the color scheme of a red metal roof and grey +white siding is inspired by the vernacular of homes in Reykjavic Iceland. The space is essentially one large south facing room with a loft and clerestory windows above.

This renovation realized an approximately 4980 sq ft of renovation to a downtown office tower in Calgary. The goal of the upgrade was to add affordable 8' x 10' offices for small business enterprises wishing to be located downtown. The addition of Herman Miller furniture and the introduction of a vibrant color scheme gave the renovation a contemporary look, complementing this distinguished modernist building. LVD executed this project in collaboration with Mark Chambers Architect Ltd.

The Glenbow Museum Gift Shop was a unique and creative opportunity to link the existing Glenbow Museum Lobby to the 8th Ave. Mall. The New street Entry to the Shop created an urban presence for the Museum, as well as a distinct space of its own. The shop is a narrow sinuous space terminating in a oval gallery display area that opens to the street and prominently features the Indigenous masks that are sold there.

Good design decisions at the earliest stages of a project will offer the best possible built project. Appropriate responses to site, path of the sun, program needs, massing strategies, planning considerations and the building sections are critical.
Conceptual and schematic design development of projects are often best explored in a format that will give enough information to the client allowing an understanding of the important ideas while still allowing room for further design development and refinement of their own vision. This often can be achieved by conceptual drawings that are resolved enough to evoke a solution yetfluidenough to be reworked and refined. Good decisions in the early stages of the project conception will prevent later more costly delays and changes.
LV also worked as a painter on commercial murals on a part time basis after graduating from architecture. The following are examples of mural projects. The first mural of the Great Barrier Reef is shown in a utility room. The second mural is a 7' high by 4' wide wall painting of the Soho district in New York City is shown in a bedroom.
These labels are made from lino cut block prints of various flowers from Southern Alberta and BC. The colors are changed for the various seasons and they are the perfect compliment for the handmade Huckleberry Wine. Wild Huckleberries are a high altitude berry found in areas where trees have been clear cut in the mountains. They are not easy to find and not easy to pick since the areas for growing are so remote.
The site of this new 2700 sq ft. Residence is oriented east west allowing the back yard and Second Floor of the home a view of the top of the Calgary Skyline. The challenges of the project lay with introducing light throughout the home in such a narrow lot and to give the home a contemporary look while blending in with the existing fabric of the street.
