This educational / practical article teaches readers how to estimate total material cost when designing furniture, kitchens, cabinetry, or interior fit-outs. It walks through calculating surface area, allowing wastage (5-10 %), choosing appropriate sheet types (MDF, laminated MDF, plywood, veneer), and using current market prices (for lamination sheets, Patex, MDF, veneer, plywood) to produce a cost estimate. We include sample worksheets, margin buffers, and a sample cost-breakdown using real quotes. A great guide for contractors, startups, or clients planning budgets.
