Outdoor Spaces Built for Real Use

Additions & Exterior Structures in Eastern Colorado and all of Kansas for property owners seeking functional outdoor environments

CNC Marez Exteriors LLC designs and builds custom exterior additions that extend your property's usable space beyond the footprint of your home. These structures include covered patios, outdoor living areas, shade structures, and other exterior enhancements that respond to how you actually use your property. Each addition is planned to match the existing architecture so the new construction appears intentional rather than attached as an afterthought.


The process begins with evaluating the site conditions including drainage patterns, sun exposure, wind direction, and access points to determine where structures will perform best over time. Proper foundation work and material selection prevent settling, moisture infiltration, and weather-related deterioration that often compromise exterior additions within the first few years. The design phase accounts for how the structure integrates with existing rooflines, siding materials, and architectural details so everything reads as cohesive.


Schedule a property evaluation to review site conditions and discuss structure options that fit your outdoor use patterns.

What Proper Exterior Structure Construction Requires

Building an exterior structure involves coordinating footings that account for soil composition and load distribution, framing that accommodates weather exposure and structural loads, and finish materials that withstand constant UV exposure and temperature fluctuations. Covered patios require drainage planning so water sheds away from both the new structure and the existing home, while posts and beams must be sized to handle wind loads specific to the structure's height and roof area.


Once construction is complete, you notice defined outdoor spaces that function in weather conditions that previously made your yard unusable. Covered areas provide shade during peak sun hours and shelter during light rain, while open patios create gathering spaces that feel like extensions of interior rooms. The structures remain stable through seasonal temperature swings and storm events because the foundation and framing were engineered for long-term exposure rather than minimal code compliance.


Additional considerations include whether electrical or plumbing lines need to be run to the structure, how the addition affects property drainage, and whether existing landscaping requires modification. Structures built near property lines may require setback verification, and roof-attached additions must integrate flashing details correctly to prevent leaks where new construction meets old.

What to Know Before You Start

Property owners planning exterior additions often ask about design options, construction timelines, and how new structures affect existing systems.

  • What determines the best location for a covered patio or exterior structure?

    Site drainage, sun angles throughout the day, proximity to existing doors and windows, and how you plan to use the space determine placement, since structures positioned incorrectly create water problems or remain unused despite the investment.

  • How do exterior additions integrate with existing architecture?

    Matching rooflines, siding profiles, trim details, and color palettes ensures new construction complements rather than clashes with your home, which involves sourcing materials that coordinate with existing finishes and replicating design elements like fascia profiles and soffit details.

  • What foundation work do outdoor structures require?

    Concrete footings extend below the frost line to prevent heaving, with pier spacing and depth calculated based on structure size and soil bearing capacity, since inadequate foundations cause settling that pulls structures away from homes or creates uneven surfaces.

  • When should exterior construction be scheduled in the Eastern Colorado and Kansas area?

    Planning construction during dry weather prevents soil disturbance and foundation issues, while cooler months may extend concrete curing times but reduce heat-related material expansion that can complicate framing and finish work.

  • What increases property value more effectively than basic structures?

    Custom design elements that extend the home's style outdoors, quality materials that require minimal maintenance, and functional layouts that create defined activity zones contribute more to property value than generic prefabricated structures that look temporary.
