Contact us at Leah Ervi Design to schedule your in-person consultation. We will go over your individual design goals and ways to achieve them within your budget and timeline.


After feedback from our initial consultation, you can decide the scope of your project. You may want to start with one area or tackle the entire house. With this, we will present ideas within your style and budget using moodboards, pictures, architectural drawings, floor plans, illustrations, and 3D renderings.

We can: prepare and file projects for permits, recommend reliable construction contacts, provide site management, create architectural drawings, and present furnishing such as: tiles, marble, carpets, light fixtures, and audio and visual components, all within your style and budget. We can also store all new furnishing until your project is ready for delivery and placement of furnishing.
