Quick Answer:

When to Hire an Interior Designer St. Louis

Hire your designer during pre-design or schematic design - ideally before final architectural drawings. Early collaboration lets us influence layout, lighting, millwork, windows, and budget - protecting your investment and reducing change orders. If you’re already further along, it’s still worth bringing us in now (here’s how we plug in at each stage).

The Ideal Timeline: Stage by Stage

1) Pre-Design (Before Architectural Drawings)

• Programming: We interview how you live (morning routines, entertaining, storage needs, pets, hobbies, etc) and align on goals and investment ranges.

• Visioning: Inspiration audit, hero materials, preliminary color story, and style directions rooted in timeless design principles.

• Space Planning Inputs: We outline furniture needs and functional adjacencies that inform the architect's early layout.

• Preliminary Budget: Early Guidance on finish levels and furnishings so expectations are realistic from day one.

  
  

Why it matters: The earlier we're involved, the earlier (and less expensive) it is to optimize rooms, window placements, door swings, and built-ins for the way you live.

2) Schematic Design ( Design Creation of Initial Plans + Options)

• Furniture Plan Review: Validate room sizes, traffic paths, and seating counts so layouts are effortless.

• Lighting Strategy: High-level plan for fixtures, layers, and switching that supports mood and function.

• Millwork + Wallpaper Concepts: Identify opportunities for built-ins, trim profiles, and unique wallpaper.

• Appliance + Plumbing Planning: Ensure clearances and rough-ins align with cabinetry elevations and future Phase II design plans.

3) Design Development (Design Creation of Detailed Drawings + Selections)

• Selections + Specs: Cabinetry, surface, plumbing, lighting, hardware, paint, wallcovering.

• Elevations + Tile Layouts: Tile pattern elevations, slab seam diagrams, cabinetry details.

• Finish Schedules: Lighting, plumbing, hardware, paint and wallcovering schedules for on site reference.

• Spec Book: Consolidated documentation to reduce jobsite questions, bidding ambiguity and to maintain the integrity of the design.

4) Pre-Construction (Permits, Final Pricing, Ordering)

• Bid + Allowances Review: Apples-to-apples comparisons and scope clarifications.

• Lead Time Strategy: Sequence orders to avoid delays; identify long-lead times.

• Site Walkthroughs: Pre-start alignment with builder and trades.

5) Construction (Framing to Finishes)

• Milestone Visits: Framing, rough-in checks, tile set-out, slab positioning, fixture heights.

• RFIs & Field Decisions: Quick answers backed by the design intent.

• Quality Review: Ensure specs are followed; resolve issues before they become change orders.

6) Furnishings + Installation (Your HGTV Moment- minus the stress)

• Procurement: Order, track, receive, and inspect furnishings.

• Installation & Styling: White-glove delivery, art placement, window treatments, and accessories.

• Reveal Day: A finished home that looks incredible and lives even better.

FAQs

When should I hire an interior designer for a new build?

At pre-design or schematic design - before drawings are finalized - so we can influence layout, lighting, and millwork while it’s still inexpensive to change.

Is it too late if construction already started?

No. We can still protect your investment by catching issues early, coordinating finishes, and guiding field decisions.

How does timing affect my budget?

Early decisions reduce rework and change orders, so your overall cost often goes down even with professional design fees.

Can you work with my existing architect and builder?

Absolutely. We thrive in collaborative teams and often join early to keep drawings, schedules, and specs aligned.
