The aim of DESIGN-STEW is to be scrupulous and transparent. After an initial conversation, I create a proposal for which I charge a fee. Should we decide to work together I bill for my time by the hour and I charge a 10% mark-up over trade pricing for purchases. Because the interior design industry has often historically relied on obfuscatory billing practices, I provide clients with receipts for materials. The only padding you'll be subjected to is in your newly upholstered chairs.
