7 ways to save on Florida custom construction

1. Use a production plan as starting point — cheaper than full architect-designed from scratch
2. Build rectangular, not complex shapes — angles and curves add 10–15% to framing
3. Standard ceiling heights — 9ft and 10ft are cheapest, soaring ceilings add 15%
4. Consolidate plumbing walls — stacked bathrooms and back-to-back plumbing save thousands
5. Choose standard window and door sizes — custom sizing doubles cost
6. Delay pool and landscaping — do them post-closing, pay with your own money instead of financing them into the loan
7. Avoid mid-project design changes — every change order costs 2–3x what the original would have cost

Typical timeline for Florida custom construction

• Design phase: 2–4 months (architect, plans, approvals)
• Permitting: 2–4 months (varies dramatically by county — Miami-Dade slowest)
• Construction: 9–14 months
• Final inspection and certificate of occupancy: 1 month
