Slope Light House Narrow-Lot 1986 is a $287,800 construction-scope concept for a 1986-square-foot shed-roof contemporary family home. This guide helps U.S. readers compare the intended size, rooms, sample cost allocation, and savings milestones. It is not a home listing, contractor bid, appraisal, or ready-to-build plan.
Planning target: $287,800 covers only the illustrative house scope and allowances below. Land, major site work, permits, utility connections, financing, and professional services are excluded.

Exterior and floor-plan concept
The exterior uses light taupe panels with charcoal and cedar-look accents, two opposing dark shed roofs, and a recessed entry beneath the roof overlap. The image is a conceptual visualization created for design inspiration, not a photograph of a property offered for sale.
The defining planning idea is a compact stair and plumbing core, rooms organized front to back, side-window privacy, and garage access that protects living-space width. The main level groups the kitchen, dining, great room, storage, and a flexible office or guest space. Most bedrooms and laundry sit upstairs or on the daylight level around a compact circulation core.
Best fit: Buildable urban or close-set suburban lots where frontage is limited.
Design decisions for narrow-lot living
Planning priority: a compact stair and plumbing core, rooms organized front to back, side-window privacy, and garage access that protects living-space width.
Main tradeoff: A narrow footprint saves frontage but can make daylight, furniture paths, and garage placement harder to balance. This is why the concept should be tested against furniture, daylight, privacy, structure, and local site constraints before drawings are commissioned.
Compare this idea with the complete Family Homes collection, then use the project photo gallery to save exterior and material references before meeting a local designer or builder.

What the target assumes
This target assumes cost-conscious regional builder with standard finishes, a straightforward buildable site, standard-grade materials, competitive local bids, and limited change orders. A custom turnkey contract in a high-cost U.S. market can be substantially higher.
- A code-appropriate structure using practical spans, efficient plumbing runs, and stock-size openings.
- Standard cabinetry, counters, flooring, lighting, plumbing fixtures, and appliances rather than luxury selections.
- The garage allowance applies only as described; workshops, bonus rooms, and elaborate driveways are separate.
- Every allowance is replaced with current local quotes before land purchase, financing, or construction.
Costs not included
- Land, closing costs, loan interest, lender fees, property taxes, insurance, or real-estate commissions.
- Survey, clearing, demolition, grading, driveway, drainage, retaining walls, rock work, or contaminated soil.
- Utility extensions and hookups, septic, well, municipal impact fees, or unusually long service runs.
- Permits, plan review, inspections, architecture, engineering, energy testing, or construction documents.
- Detached structures, pools, major decks, fencing, furnishings, window treatments, or finished landscaping.
A simple savings target
Someone choosing to save the full concept amount in cash would need approximately:
- 10 years: $2399 per month for 120 months
- 20 years: $1200 per month for 240 months
- 30 years: $800 per month for 360 months
These are arithmetic examples only. They do not model investment returns, inflation, taxes, mortgage terms, future price changes, or financial suitability.
Before using this model
- Confirm zoning, minimum size, setbacks, access, utilities, and design rules locally.
- Price land, site work, permits, foundation conditions, utilities, and professional work separately.
- Have qualified professionals verify structure, energy, fire safety, egress, electrical, plumbing, and mechanical systems.
- Compare at least three current written bids using the same scope and retain an additional real-project contingency.
Why location can change the result
Labor rates, material availability, codes, climate loads, taxes, and site conditions vary widely across the United States. National data provide context but cannot price a specific project.

Questions about this 1986-square-foot concept
Is $287,800 the purchase price of this home?
No. It is an educational construction-scope target for comparing priorities. The home, land, plan set, permits, site work, professional services, and financing are not being offered for $287,800.
What makes this a narrow-lot layout?
The concept emphasizes a compact stair and plumbing core, rooms organized front to back, side-window privacy, and garage access that protects living-space width. A local professional must confirm dimensions, code compliance, structure, and whether that arrangement works on a specific parcel.
What should be priced first?
Start with the land constraints, utilities, foundation conditions, shell, and major mechanical systems. Then compare the cost of the defining feature against its principal tradeoff: a narrow footprint saves frontage but can make daylight, furniture paths, and garage placement harder to balance.
