Bump-Out FAQs
Cantilever bump-outs typically extend 2-4 feet without additional foundation. With piers or a small foundation, you can go 6-15 feet or more.
Significantly cheaper. A bump-out adding 50-100 sq ft costs $15-25K, while a full room addition of similar size would cost $40-60K due to foundation and roofing complexity.
Kitchens (for islands or pantries), bathrooms (for showers or tubs), and dining rooms (for seating) are most popular. Even 3-4 feet can transform a cramped space.
Most bump-outs are completed in 2-4 weeks, much faster than full additions. Minimal foundation work and simple roofline integration speed the process.
