Westmount stands as Montreal's crown jewel of luxury real estate, where Tudor mansions and Georgian estates demand outdoor spaces that match their architectural grandeur. As Canada's largest luxury landscaping and pool company with over 25 years of expertise, Northstone Group has become Westmount's trusted partner in creating sophisticated outdoor environments that respect the municipality's strict bylaws while delivering resort-style luxury. Featured in House and Home, Dwell Magazine, Montreal Gazette, and Haute Living, our team of 180+ professionals, including in-house landscape architects, specializes in transforming Westmount properties into private sanctuaries that seamlessly blend with the neighborhood's distinguished character.
Understanding Westmount's Unique Landscape Requirements
Westmount's architectural heritage and municipal bylaws create a unique landscape that demands expertise beyond typical pool and landscaping projects. The City of Westmount maintains some of Quebec's most stringent property regulations, particularly regarding front yard treatments, natural stone requirements, and pool installations. At Northstone Group, our in-house landscape architects possess intimate knowledge of Westmount's specific bylaws, ensuring every project not only meets but exceeds municipal standards while preserving the neighborhood's cherished aesthetic.
Westmount's Natural Stone Requirements
One of Westmount's defining characteristics is its extensive use of natural stone, particularly in front yard applications. The municipality's bylaws specifically require natural stone for retaining walls, walkways, and front entrance features to maintain the area's historic character. Northstone's extensive experience working with natural stone makes us uniquely qualified to handle Westmount's requirements. Our expertise includes:
Premium Stone Selection
Locally sourced limestone matching existing Westmount architecture
Imported granite for contemporary applications
Heritage-appropriate fieldstone for traditional properties
Custom-cut flagstone for elegant walkways and patios
Expert Installation Techniques Our craftsmen specialize in dry-laid stone construction, a technique particularly valued in Westmount for its authentic appearance and superior drainage. This traditional method, combined with modern engineering principles, ensures structures that withstand Quebec's freeze-thaw cycles while maintaining the timeless elegance Westmount demands.

Custom Concrete Pools: Engineering Excellence for Westmount Properties
Westmount's hillside location and mature landscape present unique challenges for pool construction that only experienced builders can navigate. Northstone exclusively builds concrete and gunite pools, the only construction method robust enough to handle Westmount's varying elevations and soil conditions while meeting the municipality's strict engineering requirements.
Why Concrete Pools Excel in Westmount
Topographical Adaptability Many Westmount properties feature significant grade changes, particularly those on the mountain's slope. Concrete pool construction allows us to engineer pools that work with challenging topography, creating stunning infinity edges that capture views of downtown Montreal or intimate courtyard pools nestled into hillside gardens.
Architectural Harmony Westmount's diverse architectural styles—from Victorian mansions to modernist estates—require pools that complement rather than compete with existing structures. Concrete's unlimited design flexibility enables our in-house landscape architects to create pools that appear as natural extensions of your home's architecture.
Heritage Property Considerations For Westmount's numerous heritage properties, concrete pools offer the precision necessary to work within restricted spaces without disturbing mature trees or historic landscape features. Our 3D design technology allows property owners to visualize exactly how the pool will integrate with existing elements before any ground is broken.
Westmount Pool Design Trends
Classic Elegance Many Westmount homeowners prefer timeless rectangular pools with formal geometric lines that echo their property's traditional architecture. These designs often feature:
Natural stone coping using materials that match the home's facade
Integrated spa areas with traditional tile work
Formal water features including fountains and scuppers
LED lighting systems for evening entertainment
Contemporary Statements For Westmount's modern residences, particularly in Upper Westmount, we create architectural pools featuring:
Perimeter overflow designs creating mirror-like surfaces
Glass tile finishes in sophisticated neutral palettes
Integrated fire features for dramatic evening effects
Smart pool technology for automated maintenance and control
Comprehensive Landscaping: Beyond the Pool
At Northstone, we understand that Westmount properties require comprehensive landscape design that extends far beyond pool construction. Our in-house landscape architects create cohesive outdoor environments that respect Westmount's garden heritage while incorporating modern luxury amenities.
Front Yard Excellence: Meeting Westmount's Standards
Westmount's bylaws place particular emphasis on front yard presentations, requiring approved materials and design approaches that maintain neighborhood consistency. Our landscape architects excel at creating front entries that satisfy municipal requirements while expressing individual style:
Natural Stone Integration
Custom-designed stone pillars and entrance walls
Heritage-appropriate walkways using local limestone
Integrated planting pockets for seasonal color
Professional drainage systems preventing ice buildup
Heated driveways with concealed snow-melt systems
Planting Design Westmount's mature tree canopy and established garden character require sophisticated planting designs that complement existing vegetation. Our designs incorporate:
Shade-tolerant understory plantings for tree-lined properties
Four-season interest through careful plant selection
Native species supporting local ecology
Formal hedge installations maintaining privacy
Seasonal color rotations reflecting Westmount's garden tradition

Backyard Transformations: Creating Private Resorts
While front yards must respect Westmount's public face, backyards offer opportunities for personal expression within municipal guidelines. Northstone's comprehensive approach creates seamless transitions from indoor to outdoor living:
