Who is TALD for?

TALD is for homeowners planning new builds, renovations, or design updates — and for businesses creating beautiful, functional spaces. Whether you're working on a primary residence, vacation home, or boutique commercial space, TALD connects you with trusted experts in architecture, interior design, build, and landscape design to bring your vision to life.

Who are the professionals on TALD?

TALD connects you with a curated community of trusted architects, interior designers, builders, and landscape designers. Each professional has been invited based on vision, expertise, and a proven track record of client satisfaction.

I only have a few questions. Is a consultation right for me?

Absolutely. Whether you're seeking fast-acting advice or diving into a full transformation, our community of designers is flexible when it comes to project size and scope. No question is too small, and no vision is too grand.

How should I prep for my consultation?

Gather anything that helps communicate your goals — floor plans, sketches, photos, inspiration images, or materials. Whether the conversation centers on architecture, interior design, construction, or landscaping, the more prepared you are, the more productive your consultation will be. Family members, architects, and contractors are welcome to join the call to maximize your time.

How long are TALD consultation calls?

You can book a 30-minute or 60-minute consultation. A 30-minute session is ideal for focused questions — like finalizing a kitchen layout, reviewing material options, or refining a landscape concept. A 60-minute session allows for deeper collaboration, especially helpful for larger home projects or boutique commercial spaces.

I'm planning a full project. Should I book a consultation or full-service?

If you want a trusted professional to manage your project from concept to completion — whether it's building a new home, renovating a historic property, or designing a boutique commercial space — submit a full-service inquiry. If you're taking a more hands-on approach but want expert input along the way, a consultation is a smart fit.

How do I find the right professional for my project?

Browse TALD's trusted community of architects, interior designers, builders, and landscape experts by location, project type, style, budget and more. Explore editorial features to understand each professional's approach. From there, you can book a consultation or submit a full-service project request.

What is TALD's cancellation policy?

Please reschedule or cancel your consultation at least 48 hours in advance to avoid being charged in full.
