Do Interior Designers Handle Installation and Construction?

5 June 2026 · 4 min read

The answer depends on which package you've hired. And the difference matters far more than most clients initially realise. For a full overview of what each engagement type covers, see our services page.

Design-Only: What It Means for Execution

A design-only engagement ends when we hand you the documentation package — floor plans, renders, BOQ, material specifications, vendor recommendations. What happens after that is between you and your contractors.

You're the project manager. You call the carpenter. You follow up on the electrician. You check that the tile being installed is the one in the specification. You catch the problem when the contractor substitutes cheaper material on site.

This is completely manageable if you have the time and the willingness to be on site regularly. Many of our design-only clients do this effectively. But you need to know it's your responsibility before you sign up for design-only.

Execution Package: What Supervision Actually Means

When you're on our execution package, we're managing the project end-to-end:

Vendor management — we source, brief, and coordinate the carpenter, electrician, tile contractor, false ceiling contractor, painter, and any other trades. You have one point of contact (us) rather than four.

Site visits — regular visits at key milestones to check that work matches specifications. Not just a look — an actual comparison against the approved drawings and material specs.

Material verification — we check that what's being installed is what was specified. Material substitution is one of the most common forms of cost-cutting by contractors and it's almost invisible to clients who aren't checking.

Timeline management — coordinating that contractor B can start when contractor A finishes, without the two-week gap that happens when clients manage it themselves.

What Execution Supervision Prevents

The three things that most commonly go wrong without supervision:

1. Material substitution — contractor uses ₹800/sqft ply instead of ₹1200/sqft ply. You can't see it once the laminate is on.

2. Timeline slippage — no one to hold contractors to a schedule. A 12-week project becomes 20.

3. Miscommunication on details — contractor interprets the drawing differently from how the designer intended. Without the designer on site to catch it, the wrong detail gets built.

The Cost Difference

Execution management adds roughly 30-50% to the project management cost compared to design-only. But it typically saves money overall — through vendor relationships (better prices), material quality control (no hidden substitution), and timeline management (fewer carrying costs on a delayed project).

Which Is Right for You?

Have a trusted contractor you've worked with before? Design-only is probably right. Give them our documentation and let them execute.

Starting from scratch in a new flat with no contractor relationship? Execution package. The vendor network we bring is worth more than the management fee. Read our related post on what's included in a design-only package for more detail.
