Residential Interior Design Pricing
At Triumph Design and Construction, we provide clear and competitive pricing for residential projects. Costs depend on space size, design complexity, and material selection. High-end residential design requires detailed planning, system design, and smooth circulation flow. These factors increase complexity, leading to higher pricing than standard residential design. Below is a general guide to help you estimate your budget.
Commercial Interior Design Pricing
Commercial projects are priced based on the functional design area. Larger spaces may have open zones. It reduces the price per square meter compared to compact, detail-heavy spaces. Luxury commercial designs, like hotels and high-end retail stores, need custom layouts, branding, and special fixtures. This adds complexity, making them more expensive than basic commercial interiors. Below is a general guide to help you plan your budget.

Payment Structure & Installment Plan
At Triumph Design & Construction, we follow a structured payment schedule to ensure a smooth, transparent, and well-managed construction process. Our installment-based payment system aligns with project milestones, allowing clients to track progress while ensuring efficient execution. We divide the total project cost into five structured payments, ensuring fairness and accountability at each phase:
1st Installment – 40% (Project Kickoff)
Once the contract is signed, the project officially begins. This initial payment covers design planning, material procurement, and scheduling of construction work.
2nd Installment – 30% (Midway Progress)
When approximately 50-60% of the project is completed, including major structural work and built-in installations, the second payment is required. At this stage, clients can visibly see the transformation taking shape.
3rd Installment – 20% (Final Assembly & Installation)
After all furniture, fixtures, and design elements have been fully installed, this payment ensures that the final adjustments and finishing touches are completed efficiently.
4th Installment – 5% (Final Inspection & Cleaning)
Before the official handover, we conduct a thorough inspection, make final refinements, and carry out deep cleaning to present a flawless space.
5th Installment – 5% (Project Handover & Acceptance)
The last installment is due upon project completion, including site inspection, final approval, and client acceptance in writing.
This structured approach ensures clarity, minimizes financial risks, and guarantees that the project is completed to the highest standards. If you have any questions about our payment process, feel free to contact us for more details.
