Let’s pull back the curtain a little because design fees can feel unnecessarily mysterious.
As a general planning tool, full service interior design fees often land somewhere around 15–25% of the overall project investment. Sometimes less, sometimes more. The size, scope and complexity of the project matter.
So when we say “it depends” or we won’t know until we proceed with a paid consultation that isn’t a cop out. No two projects are exactly alike in their needs.
At Et Sal, we use two different fee structures within the same project. The design phase is a flat fee and once we move into implementation, our time is billed hourly against a time bank.
We structure ours the way we do because I want the actual design clearly defined from the beginning and after years of doing this I know what our team does to ensure the plan. The actual build or remodel part of the job is the unpredictable part of bringing it to life. The fee structure reflects the amount of work it actually requires.
And because I believe in radical honesty, I think real numbers are helpful. If you’re planning a $1M project and hoping your design fees will be $30,000, we’re not the right studio for you. I’d much rather you know that before you ever fill out our inquiry form.
Some projects will fall below that 15–25% range and some will absolutely fall above it. But if you’re sitting at home trying to figure out what you should realistically set aside to hire a full service interior design studio, it’s a pretty good place to start.
There. One less mysterious thing about hiring an interior designer.
