Exterior Design: Working with Your Custom Home Builder

Your custom home’s exterior sets the tone for everything that happens inside. From rooflines and siding choices to the color on the front door, there are dozens of design decisions to make—each one affecting curb appeal and long-term maintenance.

This article presents ideas for choosing an architectural style, evaluating your lot and neighborhood context, selecting materials and colors, specifying doors/windows/features, and planning landscaping and hardscaping. Along the way, we’ll share how a trusted Eastern Idaho builder like Guardian Homes collaborates with you to balance beauty, function, and budget.

Select an Architectural Style

Choosing a style is the first—and arguably most defining—decision for your exterior.

Modern: Clean lines, large panes of glass, and simple forms. Materials often include smooth stucco, fiber-cement panels, metal accents, and low-contrast palettes. Expect minimal trim and a strong connection between interior and exterior spaces.

Modern Farmhouse: Gable roofs, vertical board-and-batten siding, wide porches, and warm wood or stone accents. Black windows, simple brackets, and a cheerful front door color give it contemporary life without losing rustic charm.

Craftsman: Low-pitched roofs, deep overhangs, expressive rafter tails, tapered columns, and mixed materials (shingle, lap siding, stone). Earthy color schemes and prominent porches create a welcoming, handcrafted feel.

Colonial: Symmetry rules: centered entry, evenly spaced windows, and classical details. Brick or painted lap siding paired with contrasting shutters and a statement door works beautifully here.

Cabin-Style/Mountain Contemporary: Think about placement in view-rich areas. Combining timber, stone, and metal roofs. Broad overhangs and covered outdoor rooms anchor the home to its landscape.

Consider the Context of Your Custom Home

A beautifully designed exterior doesn’t exist in a vacuum; it should respond to its surroundings.

Neighborhood Fabric: What’s typical nearby—farmhouse, ranch, craftsman? You can complement those patterns without copying them.

Blend In vs. Stand Out: A tasteful contrast—such as modern forms expressed in traditional materials—keeps your home distinctive yet harmonious.

HOA and  Zoning: Review height limits, setback rules, exterior material restrictions, and color approvals early. It protects your design timeline and helps you allocate budget where it counts.

Orientation and Sun: The direction your home faces affects how colors read, where snow and ice accumulate, and how outdoor spaces perform. North façades in colder climates benefit from protective detailing; south and west exposures may need shading.

Views and Privacy: Don’t waste an incredible mountain or valley view—lean into it with window placement, covered decks, and rail solutions that preserve sightlines. Meanwhile, consider screening from neighbors using fences, trellises, and layered plantings.

Choose Materials

The right materials bring your style to life and stand up to Eastern Idaho’s seasons.

Popular Exterior Materials

Brick & Stone: Classic, durable, and low maintenance; excellent for foundations, wainscoting, or chimney masses.

Stucco: Clean look for modern or Spanish-influenced designs; specify high-quality mixes and professional installation.

Wood (Cedar/Accents): Warmth and character; plan for periodic sealing or staining.

Fiber Cement: Versatile styles (lap, panel, board-and-batten), strong fire resistance, and comparatively low upkeep.

Vinyl: Cost-effective with improved profiles; best for simpler detailing.

Metal: Vertical standing-seam siding or roofing is striking and sheds snow well; consider snow guards where appropriate.

Eco-Friendly Options

Here are some ideas for eco-friendly exterior options:

• Recycled or sustainably sourced siding and low-VOC (volatile organic compound) paints reduce environmental impact and improve air quality.
• Energy-efficient windows and insulation help stabilize interior comfort and lower utility bills.
• Solar-ready roofing (or integrated solar panels) can pair with standing-seam metal or composite shingles designed for mounting systems.

Mixing Materials 

Blend two or three complementary materials to create depth: stone at the base, lap siding as the field, and board-and-batten in gables; or smooth stucco with warm wood soffits and a metal entry canopy. Use changes in plane—bump-outs, porches, or bays—to transition materials gracefully. Keep trim consistent to tie it all together.

Durability and Maintenance in Eastern Idaho

Cold, snow, and freeze-thaw cycles demand robust detailing. Aim for:

• Proper roof pitch and overhangs to shed snow and protect walls
• Ice-dam mitigation via continuous insulation, air sealing, and ventilated roof assemblies
• Durable cladding with appropriate clearances from grade and well-flashed openings
• Finish usage that matches your accepted scope for upkeep (e.g., stained wood accents in smaller, protected doses)

Pick the Color Palette

This can be one of the most exciting parts of designing your custom home. Here are some ideas to consider:

Choose a Base Color

Decide whether you want a neutral base (white, greige, taupe, charcoal) that’s easy to accessorize or a bold statement (deep navy, forest green, near-black) that gives the home presence. Remember that colors read lighter in strong sun and can shift cool/warm based on surroundings like evergreens, snow, or red-brown soils.

Accents that Elevate

Trim, shutters, siding reveals, soffits, and especially front doors and garage doors are prime opportunities to introduce contrast. A mid-tone house with a dark metal roof and a wood-tone door is timeless; a white farmhouse with black windows and a cheerful front door feels both classic and current.

Tools for Visualization

Use online renderings, digital paint tools from major manufacturers, and sample boards with real materials. Examine boards outside at different times of day to see how morning vs. afternoon light changes the palette. Work with your builder to coordinate mockups so you feel confident before ordering.

Determine Doors, Windows, and Features

Doors, window styles, and exterior features all add to the overall appearance of your custom home.

Front Door Style and Statement

Pick the right profile (full-lite, shaker panel, plank) in a material that suits your aesthetic—fiberglass or wood-look fiberglass for durability, or true wood in a protected alcove. Tie in hardware finishes with house numbers and sconces for a cohesive entry.

Window Design

Choose a consistency: casement or awning for modern tight lines, double-hung for traditional styles, sliders where wide horizontal openings make sense, and transoms to bring in top light. Coordinate grille patterns with the architecture—simple for modern, more divided for colonial or craftsman.

Architectural Features

Columns, gables, dormers, porches, overhangs, brackets, and planters shape the façade’s rhythm. In snowy climates, generous overhangs and covered entries are not just pretty—they’re practical. Consider a timber or metal canopy over garage doors, or a breezeway that links home and accessory structures while creating wind-protected outdoor space.

Specify Landscaping and Hardscaping

The environment around your home can help establish an overall atmosphere and draw cohesion with your home’s structure and design.

Driveways, Walkways, and Lighting

Concrete, pavers, and compacted gravel each set a different tone. Use curves to soften long approaches and path lighting to guide the eye to the entry. If the budget allows, run sleeve conduits for future lighting, irrigation, or gate automation so upgrades are painless later.

Plantings and Greenery

Layer trees, shrubs, and perennials to frame the architecture. Evergreen structure can add interest in winter; ornamental grasses and flowering shrubs add seasonal movement and color. Choose low-water, region-appropriate species to simplify maintenance and support sustainability.

Outdoor Living Spaces

A covered patio or deck, privacy fencing, and wind-smart screening extend your living room outward. Think of exterior “zones”: a quiet morning corner, a grill station close to the kitchen, and a generous dining area with string lights. Durable surfaces—stamped concrete, composite decking, or stone—age gracefully and clean up quickly after long winters.
