  • Permits & Design (5%): Government approval fees and architectural design charges.

Design Tips from
Professional Architects

Bulk-purchase cement and steel during the 'Off-season' (Pre-monsoon) to save 5-8% on civil costs.

Using 'Standard Size' windows and doors reduces fabrication waste and labor costs significantly.

Invest in 'Fly-ash Bricks'—they are more uniform, use less mortar, and provide better insulation than traditional red bricks.

Planning for a 'Stilt Parking' initially costs more in foundation but saves you the cost of internal parking room area on the ground floor.

Get a 'Bill of Quantities' (BOQ) from your architect before starting; it is your only weapon against contractor overcharging.
