BEST VALUE FOR MONEY Imagimax is 22% below market standard (UAP) and PHP 1.6M cheaper than Casas for the same floor area. 2. APPROPRIATE FIT FOR THE PROJECT This is a summer house in Laguna — not a landmark commercial building. Casas is a premium Makati firm with Makati-level rates. That premium is not justified for a provincial secondary residence. 3. BUDGET EFFICIENCY The PHP 1.6M saved goes directly into construction quality — pool, premium finishes, smart home, landscaping. A better-finished house beats a more expensive design fee. 4. WITHIN UAP STANDARDS Imagimax's pricing is fair and market-rate. No red flags. WHEN CASAS WOULD MAKE SENSE: • Primary residence, not a summer house • Portfolio prestige matters (architect credentials) • You require full 12-month construction supervision • Budget is not a constraint SECTION 7 — NEXT STEPS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ □ Request Imagimax's timeline (phase-by-phase schedule) □ Request Imagimax's portfolio (similar 400 sqm projects) □ Clarify construction phase supervision approach □ Confirm whether 2-storey quote can be updated to 3-storey □ If Casas: Negotiate down to PHP 3.5–3.8M before accepting ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Prepared by: MelAI | April 10, 2026 | Elver Residence ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
