This isn't about picking paint colors

Interior design is choosing furniture and fabrics for a finished room. Interior architecture is designing the room itself - how light enters, how spaces connect, how materials meet at every edge and corner.

Most firms separate the two: an architect designs the structure, a builder frames it, then an interior designer comes in after the walls are up - choosing finishes for spaces they didn't help shape.

At Prestige, interior architecture happens in parallel with structural design. Your interior team and build team work under Lior's management from day one. Nothing is reverse-engineered. Everything is designed together.

Four phases, one model

  1. 01

    Working alongside the architectural design by our licensed architect partners, the interior team sets the home's material language - stone, wood, metal, and finishes - as one design intent that runs through the whole home.

  2. 02

    Every finish and fixture is specified inside the live model: in the room where it will live, next to the materials it will touch, under the light it will exist in. Real products, real costs - design and budget move together.

  3. 03

    Millwork profiles, hardware, tile layouts, fixture placements, reveals, and transitions - all documented in construction-ready specifications. The builder builds exactly what was designed; nobody figures it out on site.

  4. 04

    The interior specifications go straight to Lior's build team. No translation between firms, no interpretation by a builder who was not in the design room. The people who specified the details stay involved through construction.

Award-Winning Design, Built Into Every Project

Prestige Custom has received the Best of Houzz Design award six consecutive years (2021-2026), recognizing the quality of our interior architecture across dozens of completed homes. These awards reflect the finished result - not just the design concept, but how it was executed.

That's the advantage of design-build. Design intent and construction reality are the same thing.

Two Approaches to the Same Kitchen

Every builder can install cabinets and countertops. The difference is whether your kitchen was designed as a complete, coordinated space - or assembled from disconnected decisions made by different people at different times.

Category
Typical Approach
The Prestige Approach
Design Process
Builder picks a cabinet line, you choose a color from a catalog - layout is driven by what fits, not how you cook or live
Space is designed around how you actually use your kitchen - workflow, storage, lighting, and entertaining all considered from day one
Material Selection
Countertops, backsplash, and hardware chosen separately - you hope they work together when installed
Every surface, fixture, and finish selected together inside a 3D model - you see the complete room before a single order is placed
Cabinetry & Millwork
Stock or semi-custom cabinets from a supplier's catalog - limited sizes, standard configurations
Custom millwork designed to your exact dimensions - every drawer, shelf, and panel built for the space, not adapted to fit it
Lighting
Recessed cans on a grid - functional but generic, no consideration for task zones or ambiance
Layered lighting plan - task, ambient, and accent lighting coordinated with cabinetry and architectural details
Coordination
Designer hands off selections to the builder - misalignments surface during installation
Architecture by our licensed architect partners and interior design developed together, coordinated by one team - every detail resolved before construction starts
Visualization
Mood boards and flat floor plans - you imagine what it might look like and hope for the best
Photorealistic 3D walk-through with your actual materials, fixtures, and finishes - you approve what you see, not what you imagine
Budget Impact
Discover clashes during install - tear out, reorder, and pay twice for work that should have been right the first time
Every conflict caught in the model before construction - not discovered on site
Powder room render: dark panelling, marble vanity and an arched mirror

Is this what you're looking for?

  • You're planning a new custom home or major renovation and want to understand how Prestige handles interiors
  • You want every finish and material coordinated with the architecture - not selected separately after construction
  • You're looking for a team that treats interior detailing as architecture, not decoration

This isn't a standalone service.

Prestige coordinates interior architecture as an integrated part of our design-build projects; the structural architecture is performed and sealed by independently licensed architects we work with. We don't offer decorating services for finished homes or interior-only projects without a construction component.

Questions About Interior Architecture

Answers to the questions we hear most from homeowners exploring interior architecture on Long Island.

  • Who does the architecture, and who seals the plans?

    Independently licensed architects we work with. They design and seal the architectural plans; Prestige coordinates that work, designs the interior details alongside it, and builds the home. Prestige Custom Building & Construction, Inc. is a licensed home-improvement/construction company and is not a licensed architecture firm - you get one process and one point of accountability, with the licensed design work done by the people licensed to do it.

  • What's the difference between interior architecture and interior design?

    Interior design focuses on furnishing and styling finished spaces - furniture, art, soft goods, accessories. Interior architecture shapes the spaces themselves - spatial planning, material specification, millwork, finish coordination, and architectural detailing. Prestige coordinates interior architecture as part of the design-build process, working alongside the architectural design by our licensed architect partners. We don't offer furnishing or styling services.

  • Do I need to hire a separate interior designer?

    For furniture and soft furnishings (couches, rugs, curtains, artwork), yes - that's a separate scope from what Prestige provides. But by the time we hand over your home, every built-in surface, finish, fixture, and architectural detail has been designed, specified, and installed. What you're adding is furniture to a finished space - not decorating an unfinished one.

  • Can I bring my own interior designer to work with your team?

    Yes, and it often works well. If you have an existing relationship with a designer or decorator, they can coordinate with Lior's team on furniture and soft goods while Prestige handles the interior detailing and construction. Lior will manage the integration.

  • How are materials and finishes selected?

    Inside a photorealistic 3D model of your home. You see every material in context - in the actual room, at scale, next to the other finishes. Every product is a real SKU with a real cost. The process happens before construction, so your budget is set before construction begins.

  • Is interior architecture included in the project cost or billed separately?

    Interior architecture is integrated into your design-build scope - it's not a separate line item or an add-on. The cost is part of the overall project scope that is set before construction begins.

  • What does Prestige NOT cover on the interior?

    Furniture, soft goods (rugs, curtains, upholstery), art, and accessories. We design and build every permanent element - but movable furnishings are outside our scope. We can recommend partners for that work.
