How much does an interior design cost

And what exactly is KSS

From the team of COZY. Design·Ideas for the interior

"How much does an interior project cost?" is like "how much a car costs" — it depends. The price follows the scope, area and level of completion. Here's how it's formed and why KSS is your best friend against surprises.

Area, complexity, level of detail, whether it is design only or design plus turnkey implementation. Residential and public projects are valued differently. A larger scope means more hours of design and coordination.

What is KSS?

The bill of quantities describes the quantities and value of the items included in the visualization and project — furniture, materials, lighting, etc. It turns the pretty picture into a real, trackable budget.

KSS is the bridge between the visualization and the actual budget.

Why save money

When everything is laid out in advance, you order exactly what you need, compare offers fairly and avoid repurchasing. The budget works for you, not the other way around.

  • Define scope early.
  • Request a CCA for the project.
  • Separate “must have” from “nice to have”.
  • Set aside a buffer for unforeseen expenses.

Planning from the start

We help you plan your budget realistically since the consultation. See also how the project is going step by step.

Ready for an interior with character?

We create bold, memorable interiors for home and business — in Sofia and online throughout Bulgaria.
