Concept: convertibility — adapting to future change
Peña, Problem Seeking — Ch 3 — Recurring Concept: ConvertibilityDescription
Convertibility allows for anticipated change in functional requirements. The team should set the degree of convertibility: immediate (a Murphy bed in the office), weekend (knock-out walls between an office and an adjacent guest room), or long-range (planning the office adjacent to a bathroom so it can become a bedroom in 10 years).
Why this exists
Homes outlive the configurations of their occupants. The kid's bedroom becomes a study; the in-law suite becomes a primary suite as the owners age. Designing convertibility in costs little; retrofitting it later costs a lot.
