Questions
What distinguishes interior design from interior decorating?
Interior design involves technical expertise in space planning and building codes for structural changes, while decorating focuses on aesthetics without structural modifications.
When should I engage an interior designer for my project?
Ideally at the project's inception to ensure seamless integration with architects and builders, optimizing both functionality and aesthetics from the start.
What's the difference between design consultations and full-service design?
Consultations provide expert guidance for self-implementation, while full-service design offers comprehensive management from concept to final installation.
Do you handle projects of all sizes?
We accommodate all project sizes, from single-room refreshes to complete home transformations, tailoring services to your investment level.
How are project timelines determined?
Timelines depend on project scope, with construction projects requiring contractor coordination and custom furnishings typically taking 8-20 weeks for delivery.
Can I source specified items independently?
While possible, our curated selections ensure proper scale, quality, and design cohesion, avoiding potential costly mistakes from alternative sourcing.
