Affordable House Plans: Affordable house plans are perfect for anyone who needs to keep a close eye on their budget. Affordable house plans are simple, no frills affairs that offer uncomplicated rooflines (usually a straight gable), no boxed-out or bayed windows, and a modest square footage. Everything that could increase the cost of building the house is removed from the home plan. Framing is simple and straightforward, and uses only common dimensioned lumber. All fixtures and finishes are stock. The quality is maintained, however, and, as such, our affordable house plans have remained popular for decades, with our collection containing some of the best construction plans by top home designers anywhere.
