Interior design for a new home begins before the foundation. Decisions about room proportion, windows, ceilings, lighting and cabinetry are easiest to improve while drawings are still flexible—and most expensive to revisit once construction is underway.
At JSF Design, we work alongside the architect and builder from early planning through final installation. The process keeps the interior experience connected to the architecture instead of treating it as a later layer.
We begin with how the client lives: daily routines, entertaining, privacy, collections, storage and the atmosphere the home should create. We also study the site, views, orientation and architectural direction.
This establishes priorities before the team is absorbed by individual selections.
Furniture plans test the architecture at human scale. They reveal whether circulation is generous, windows relate to the room and outlets will be useful. We review kitchen flow, bedroom suites, entertaining areas and transitions to outdoor living.

A clear concept creates continuity across a large residence. We define the material language, level of contrast, key forms and relationship to the landscape before building an extensive finish schedule.
Plans and elevations resolve fireplaces, millwork, stone, lighting and architectural details. Fixtures, hardware and appliances are selected in coordination with rough-ins and lead times. Samples are studied together and, whenever possible, in the project’s light.
Drawings and specifications communicate dimensions, products, finishes and alignments to the build team. They also support accurate pricing and create a record of approved decisions.
Complete documentation does not eliminate every field question. It gives the team a shared foundation for answering them.

During construction, we review submittals, answer design questions and visit at meaningful milestones. Framing, electrical, cabinetry, stone and lighting each require attention at different times. Collaboration protects the intent without confusing the responsibilities of the architect or builder.
Furniture is developed early enough to inform the rooms, then refined through custom pieces, upholstery, rugs, window treatments, art and accessories. Procurement includes quoting, ordering, freight, receiving, inspection and issue resolution.
The final installation brings the architecture and furnishings together. Pieces are placed, art is installed and the rooms are edited in person. The project is complete when the home feels ready to live in—not when the last order is placed.
A strong process gives a complex custom home clarity. Learn more about the JSF Design process or contact our studio before your plans are fixed.

The collaboration between Jeffrey Florentine of JSF Design and Antolini began with a shared conviction: natural stone should shape architecture, not simply finish it. Featured by Modern Luxury Scottsdale, Elementa is a collection developed with Antolini to explore how texture, proportion, light and repetition can give stone a more architectural role in the home.
