When planning a large family home, the floor plan layout determines how the household moves through daily living. A well-designed two story shingle style home balances grand entertaining spaces with private family areas. The 5,887 square foot design featured here demonstrates these principles through its circular staircase centerpiece, open concept main level, and four upstairs bedrooms. This layout serves as a useful case study for homeowners and builders evaluating spacious two-story floor plans with traditional character.
Shingle Style Exterior Design Features
Key exterior features found in this home design include:
- Wood shingle siding with natural weathering properties and R-1.0 per inch insulation value
- Stone accent walls at foundation level for moisture protection and visual grounding
- Multiple gabled rooflines that break up the 5,887 square foot mass into readable sections
- Symmetrical window placement for balanced fenestration and controlled solar heat gain
- Covered veranda with minimum 6 foot depth for weather protection and outdoor seating
The shingle style exterior combines traditional craftsmanship with functional design choices that have proven effective over decades of use. Wood shingle siding provides natural insulation and weather resistance while creating a textured facade that softens the visual mass of a 5,887 square foot structure. The siding material, typically eastern white cedar or red cedar, offers an R-value of roughly 1.0 per inch of thickness, contributing to the building envelope’s overall thermal performance.
Gabled Rooflines and Window Symmetry
Multiple gabled rooflines break up the large footprint into visually distinct sections. This design strategy reduces the monotony of a single large roof plane while creating opportunities for dormer windows on the upper floor. The dormers bring natural light into what would otherwise be dark hallway zones. Symmetrical window placement across the facade reinforces the traditional character of the design and follows the principle that balanced fenestration improves both appearance and energy efficiency through controlled solar heat gain.
Veranda and Entry Considerations
The inviting veranda serves as a transitional space between outdoors and interior. A minimum depth of 6 to 8 feet allows for seating without blocking the entry door. The covered approach protects visitors from rain and snow while establishing the home’s curb appeal. Many designers recommend installing ceiling lights and a ceiling fan on the veranda to extend its usability during warm months. Covered entry strategies similar to this appear in barn-style and farmhouse designs, showing how universal this architectural feature has become across different styles.
Circular Staircase as the Central Design Element
The circular staircase occupies the visual center of the main floor, visible from the entry and multiple adjacent rooms. This placement serves both aesthetic and practical functions. The staircase becomes a sculptural element while efficiently connecting two floors without the straight run length that a conventional staircase would require.
Space Requirements for Circular Stairs
A circular staircase requires careful dimensional planning to meet building codes while maintaining comfortable use. The International Residential Code requires a minimum tread depth of 10 inches measured 12 inches from the narrow end for circular stairways. The minimum diameter inside the handrails should be 5 feet 6 inches, with 6 feet recommended for comfortable two-way traffic.
| Staircase Configuration | Minimum Diameter or Width | Floor Opening Required | Typical Rise per Step | Headroom Clearance |
|---|---|---|---|---|
| Circular (minimal) | 5 ft 6 in | 7 ft 0 in | 7.5 in | 6 ft 8 in |
| Circular (preferred) | 6 ft 0 in | 8 ft 0 in | 7.0 in | 6 ft 8 in |
| Straight staircase | 3 ft 6 in wide | 10 ft run | 7.0 in | 6 ft 8 in |
| L-shaped with landing | 3 ft 6 in wide | 8 ft x 8 ft | 7.0 in | 6 ft 8 in |
Structural Support Systems
The staircase requires a steel or engineered wood stringer system curved to the specific radius of the design. Prefabricated curved stringers are available from specialty millwork companies and cost between 25 and 40 percent more than straight stringers. The landing platform at the top of the stairs needs additional joist support, typically a doubled joist or built-up beam, to handle the concentrated load from the staircase structure and traffic.
Open Concept Main Floor Layout
The main floor organizes the public zones around the staircase while maintaining clear sight lines across the three main living areas. This open arrangement allows natural light from windows on multiple sides to reach deep into the floor plan, reducing the need for artificial lighting during daytime hours.
Great Room and Dining Connection
The great room opens directly to the dining area without any wall separation. For the 2,800 to 3,000 square foot main floor, the combined great room and dining area typically spans 500 to 700 square feet. A gas or wood fireplace on an interior wall provides a focal point and heat source. The dining zone should accommodate a table for eight to ten people with 48 inches of clearance on all sides for chair pullback and server movement.
Kitchen and Breakfast Nook
The kitchen connects to the dining area and an adjacent breakfast nook. A large island with seating for four to six people functions as both prep space and casual dining. The work triangle between sink, refrigerator, and cooktop should measure between 12 and 24 feet total for efficient meal preparation. A walk-in pantry measuring at least 5 feet by 6 feet stores dry goods and small appliances, keeping countertops clear.
Dedicated Home Office Space
A separate office space on the main floor provides a quiet work area away from family traffic. For homes designed around flexible floor plans, this room can double as a guest room or playroom depending on changing household needs over time. The office should have at least one window for natural light and be positioned away from the great room to minimize noise transfer.
Upper Floor Bedroom Configuration
The upper floor houses four bedrooms arranged around the circular staircase landing. The stairwell creates a dramatic two-story space that draws light down from upper windows into the center of the home. This configuration places the most private spaces away from the main floor activity zones.
Primary Suite Dimensions and Layout
The primary bedroom suite occupies one wing of the upper floor for maximum privacy. Key dimensions include a bedroom area of at least 14 feet by 16 feet to accommodate a king bed with nightstands, a dresser, and a sitting area. The walk-in closet should measure 8 feet by 10 feet minimum with dual hanging rods on each side. The ensuite bathroom requires at least 60 square feet with a double vanity, separate water closet, shower, and soaking tub positioned for clear traffic flow.
Secondary Bedroom Sizing
Secondary bedrooms should measure at least 12 feet by 12 feet to fit a double bed plus a desk or dresser. Jack and Jill bathrooms between two bedrooms save square footage while giving each room direct access without a hallway. Closet depth of 2 feet 2 inches minimum accommodates standard hanger depth.
Playroom and Flexible Upper Floor Space
A dedicated playroom on the upper floor keeps toys and activities contained away from main floor entertaining areas. This space can later convert to a media room or study as children age. Some designers approach upper floor programming with flexible room definitions rather than fixed bedroom counts, allowing the homeowner to adapt the space over several decades of occupancy.
Outdoor Living Spaces and Garage Integration
Covered patios and decks extend the living area outdoors, increasing usable square footage during moderate weather. The 5,887 square foot design includes multiple outdoor zones that connect to the interior spaces through large doors and windows.
Covered Patio Dimensions and Features
The covered patio adjacent to the great room provides shade and rain protection. Dimensions of 16 feet by 20 feet accommodate outdoor dining furniture for eight people plus a grill station. Ceiling fans rated for outdoor use improve airflow, and recessed lighting on a dimmer switch extends usability into evening hours.
Garage Capacity and Storage
Two dual-car garages provide parking for four vehicles plus space for workshop benches, lawn equipment, and seasonal storage. Each garage bay should be at least 22 feet deep and 10 feet wide, with an overhead storage loft adding 150 to 200 square feet of accessible storage space.
Square Footage Distribution Across Levels
Understanding how total heated square footage distributes across floor levels helps with budgeting, HVAC zoning, and comparing similar designs. Open layouts with high total square footage benefit from efficient space planning that minimizes hallway waste and allocates area to the rooms families use most frequently.
| Floor Level | Approximate Area | Percentage of Heated Space | Primary Program Zones |
|---|---|---|---|
| Main Floor | 2,800 – 3,000 sq ft | 48 – 51% | Great room, kitchen, dining, office, foyer, powder room |
| Upper Floor | 2,200 – 2,400 sq ft | 37 – 41% | 4 bedrooms, 3 bathrooms, playroom, laundry, linen storage |
| Garages (combined) | 800 – 900 sq ft | 14 – 15% | 4-car parking, workshop area, bulk storage |
Hallway width on both floors should be maintained at 42 inches minimum for comfortable circulation, wider at corners where furniture needs to turn. The two-story layout approach used in other traditional home floor plans follows a similar strategy of concentrating family activity on the main level while reserving the upper floor for bedrooms and private functions, a pattern that has proven effective across multiple architectural styles and household sizes.
