Computed decision comparison
Deck vs patio cost
The modeled upfront totals are $11,413 for Deck and $2,611 for Patio scope proxy, a difference of $8,802.
Both options are normalized to 300 sq ft. The patio side uses the existing landscaping baseline, so excavation, base, drainage, pavers, and slab design are not implied.

Comparison questions
Which option has the lower modeled upfront cost?
Patio scope proxy is lower in the current static default by $8,802. This compares model records, not contractor proposals.
Are 10-year and 20-year replacement costs included?
No sourced lifespan field exists in the shared baseline store, so the site does not invent replacement cycles. Those horizon cells remain explicitly not modeled.
Do both options use the same source system?
Yes. Both are computed from the current baseline store and index snapshots. Any proxy, quantity normalization, or retained legacy factor is disclosed beside the option.
