Basement Renovations Whistler. Turn the lower level into valuable living space.
QUAY Construction renovates basements and lower levels throughout Whistler into guest rooms, recreation spaces, bathrooms, home offices, storage and flexible living areas through one coordinated renovation process.
Get more function from the home you already have.
Lower levels can solve some of the most common challenges in a Whistler home: guest accommodation, gear storage, recreation space, quiet work areas and additional bathrooms.
QUAY approaches basement renovations as complete interior projects, connecting layout, insulation, electrical, plumbing, flooring, lighting, storage and finishing before construction begins.
Explore Renovations Whistler ↗Better Layouts
Lower levels organized around circulation, furniture, storage and the way each space will actually be used.
Comfortable Spaces
Lighting, insulation, heating and interior finishes considered alongside the new layout.
Useful Storage
Storage planned around seasonal gear, household items, recreation equipment and everyday organization.
Connected Construction
Framing, plumbing, electrical, drywall, flooring and finishing managed through one project schedule.

Start with what the lower level needs to do.
Basement renovations work best when rooms are planned around specific functions rather than simply dividing the floor into smaller spaces. Storage, circulation, daylight, mechanical systems and furniture all influence the layout.
Build the lower level from the inside out.
Basement renovations can involve many of the same construction scopes as the rest of the home, along with additional attention to existing conditions, insulation, mechanical systems and moisture management.
Demolition
Existing finishes removed where necessary to expose the conditions behind the lower level.
Framing
Interior walls and room divisions constructed around the approved basement layout.
Electrical
Lighting, receptacles, switches and electrical requirements coordinated with the new spaces.
Plumbing
New bathroom, laundry or other plumbing requirements coordinated where applicable.
Insulation
Existing assemblies reviewed and insulation improvements incorporated where appropriate to the project.
Drywall
Walls and ceilings finished to create a complete interior rather than an unfinished lower level.
Flooring
Flooring selected around durability, comfort, existing conditions and the intended use of each space.
Finishing
Doors, trim, millwork, painting, hardware and final detailing completed before handover.
Make the lower level work harder for the household.
Whistler homes often need to accommodate family, guests, outdoor equipment and changing seasonal routines. A thoughtfully renovated basement can absorb many of those demands without changing the footprint of the home.


Give the equipment somewhere intentional to go.
Ski equipment, snowboards, boots, helmets, seasonal clothing and household storage can consume valuable living space. Lower-level millwork and storage can help organize those items without turning the basement into a storage room.

Add convenience where guests actually stay.
A lower-level bathroom can improve guest accommodation and everyday use, with plumbing, waterproofing, tile, fixtures, ventilation and lighting coordinated through the larger basement project.

Create separation without disconnecting the home.
Lower levels can give guests or family members a quieter part of the home while still feeling consistent with the materials and design language upstairs.

Basement renovation planning should account for existing ceiling heights, mechanical equipment, structure, plumbing, electrical systems, exterior walls and any signs of moisture before finishes are selected.
Ceiling Height
Existing structure, ducts and services influence ceiling planning and finished clearances.
Mechanical Systems
Heating, ventilation and equipment locations can affect room layouts and access requirements.
Moisture
Existing moisture conditions should be understood before enclosing assemblies or installing finishes.
Structure
Beams, columns and load-bearing conditions can influence the final basement layout.
New uses can change the requirements of the space.
Permit and professional requirements depend on the scope of work. New bathrooms, structural changes, regulated electrical or plumbing work and certain changes in room use can require additional review.
The existing property and proposed renovation should be assessed before construction begins so applicable requirements can be incorporated into the project plan.
Structural Changes
New openings or alterations to structural components may require engineering and permits.
New Bathrooms
Plumbing, ventilation and electrical requirements need to be coordinated around the new space.
Bedrooms
Proposed sleeping spaces need to be planned around applicable building and life-safety requirements.
Trade Work
Regulated plumbing and electrical work may require applicable trade permits and inspections.
Basement pricing starts with the existing conditions.
Final investment depends on basement size, existing finishes, framing, plumbing, electrical, bathrooms, insulation, flooring, millwork, mechanical changes and the intended use of the renovated space.

Defined Layout
Rooms and circulation are planned around structure, services and intended use.
