Modern penthouse design combines spatial efficiency with premium material selections to create living spaces that feel both expansive and refined. Whether working within an existing structure or building new, architects and designers draw on historic building renovation design approaches for urban penthouse spaces to inform their decisions. The two-story penthouse designed by the Carola Vannini studio demonstrates how limited structural changes can completely transform the look and function of a high-end residential space through thoughtful material choices and strategic layout planning.
Open-Plan Living and Spatial Flow
The first floor of a penthouse typically houses the primary living areas, and the CdA penthouse follows this pattern with a spacious living room connected to a dining area and a state-of-the-art kitchen. Connecting these spaces without walls requires careful attention to sight lines, traffic patterns, and visual continuity. Luxury penthouse design architectural features and premium materials for high-end spaces drive decisions about how each zone relates to the next.
Living Room Configuration
Large windows dominate the living room of the CdA penthouse, flooding the space with natural light and offering views of the surrounding cityscape. Window placement determines furniture layout. A sofa facing the windows takes advantage of the view while creating a natural separation between the seating area and the dining zone behind it. The living room spans 400 to 600 square feet in a typical two-story penthouse layout. Floor-to-ceiling glass maximizes daylight penetration but requires high-performance glazing to manage heat gain. Triple-pane low-E glass costs $12 to $18 per square foot installed, compared to $6 to $10 for standard double-pane windows. The investment reduces HVAC load by 15 to 25% in rooms with large glass areas.
Furniture Placement in Open Plans
Without walls to define rooms, furniture serves as the primary space divider. A sofa with its back to the dining area creates an implied separation. Area rugs define zones within the larger space. The CdA penthouse uses color coordination between the island and living room furniture to tie the zones together visually. A mosaic wall provides an artistic focal point that anchors the entire open-plan composition.
Kitchen Design and Appliance Integration
The kitchen in the CdA penthouse features high-end appliances and custom cabinetry, with the design opened toward the greenhouse and day area. This connection between kitchen and adjacent spaces requires coordinated material finishes and a cohesive color palette. The kitchen island serves as both a work surface and a visual bridge between cooking and living zones. A larger version of the kitchen has been opened up toward the greenhouse, creating an integrated space that accommodates both food preparation and casual dining. The island layout supports a natural workflow from refrigerator to sink to cooktop, reducing unnecessary steps during meal preparation.
| Kitchen Feature | Standard Specification | Premium Upgrade | Cost Impact |
|---|---|---|---|
| Cabinetry | Stock, plywood boxes | Custom, solid wood with soft-close | +40–60% |
| Countertops | Laminate or tile | Quartz or marble slab | +100–200% |
| Appliances | Standard brands | Professional-grade (Wolf, Sub-Zero) | +150–300% |
| Island Size | 4 x 6 feet | 5 x 8 feet with seating | +$1,500–3,500 |
| Backsplash | Ceramic tile | Custom mosaic or stone slab | +$800–2,000 |
Custom Cabinetry and Storage Solutions
Custom cabinetry in a penthouse kitchen serves both storage and aesthetic functions. The CdA penthouse uses cabinetry designed to match the overall contemporary style, with streamlined fronts and integrated handles. Pull-out shelves, deep drawer systems, and appliance garages keep countertops clear. Custom cabinet installation costs range from $15,000 to $40,000 depending on the kitchen size and material grades. The cabinet finish selected for the CdA penthouse coordinates with the mosaic wall colors, creating visual continuity between the kitchen and living areas. Undercabinet task lighting integrated into the cabinetry adds both function and ambiance, providing direct illumination for countertop work while contributing to the overall layered lighting scheme.
Smart Home Integration and Modern Amenities
Contemporary penthouse designs incorporate technology systems that control lighting, climate, audio, and window treatments from a single interface. The CdA penthouse reflects the latest trends in architecture and interior design, which increasingly include automated systems as standard features. Luxury penthouse design smart home integration, pre-war building renovation, and home automation have become expected elements in high-end residential projects.
Lighting Control Systems
A typical smart lighting system costs $2,500 to $8,000 for a two-story penthouse and includes dimmers, scene controllers, and occupancy sensors. The CdA penthouse design uses layered lighting: ambient ceiling fixtures, task lighting in the kitchen, accent lighting for the mosaic wall and artwork, and natural light from the large windows. Each layer serves a different function and can be controlled independently or grouped into scenes for entertaining, relaxing, or working.
Climate Control and Efficiency
Two-story penthouses present unique HVAC challenges because heat rises and the upper floor may require more cooling than the lower. Zoned HVAC systems address this by dividing the space into independent climate zones. A two-zone system for a 2,000-square-foot penthouse costs $8,000 to $15,000 installed, compared to $5,000 to $9,000 for a single-zone system of the same capacity. Programmable thermostats and motorized blinds further reduce energy consumption by adjusting to the sun angle throughout the day.
Space Optimization Through Layout Changes
The CdA penthouse project demonstrates how minimal structural intervention can produce dramatic results. The main goal was to open the interior toward the outdoor surrounding terrace. To achieve this, the architect divided the night and day areas sharply across the two floors. Day functions occupy the lower level while sleeping quarters take the upper story. Urban penthouse design open-plan layouts, premium materials, and outdoor living spaces require this kind of clear programmatic division to function well.
Vertical Zoning Strategy
- First floor: Living room, dining area, kitchen, greenhouse connection, mosaic wall feature
- Staircase: Transition space, sculptural element connecting two levels
- Second floor: Two bedrooms, two bathrooms, master suite with king bed, patio access
- Outdoor terrace: Extends living space, accessible from main level
This separation of night and day functions prevents cross-traffic between private and social zones. Guests can move between the living room, dining area, kitchen, and terrace without entering the bedroom hallway. The staircase acts as a soft filter between these zones rather than a simple circulation path. The upper floor layout places the master suite at one end for privacy, with secondary bedrooms grouped at the opposite end. This arrangement gives the primary bedroom separation from guest rooms while keeping both patios accessible from the upper level.
Master Suite Placement
The master bedroom suite on the upper floor features a king-sized bed and an en-suite bathroom with a plexiglass mounted art piece as decor. This artwork placement turns a functional space into a gallery-like experience. The second sizable patio surrounds the two bedrooms and two bathrooms on the upper story, giving each sleeping room access to outdoor space. Master suite dimensions of 400 to 500 square feet accommodate the bed, seating area, walk-in closet, and en-suite bathroom without feeling cramped.
Material Selection for Penthouse Interiors
Material choices in the CdA penthouse reflect a balance between contemporary aesthetics and practical performance. The bathroom made entirely of glass exudes elegance but requires specific maintenance protocols. Glass bathroom surfaces need daily wiping to prevent water spots and periodic treatment with hydrophobic coatings applied every six to twelve months. The cabinet filled with scents adds a sensory layer to the design, demonstrating how material selection extends beyond visual appearance into tactile and olfactory experiences. Each finish and furnishing in the penthouse was designed and made by the architect to create a warm and uniform environment. Pre-war New York penthouse design structural architecture and interior features provide historical context for modern material innovations like these, showing how contemporary materials update traditional spatial strategies.
| Material | Application | Advantages | Considerations |
|---|---|---|---|
| Glass | Bathroom enclosure | Visual openness, light transmission | Daily cleaning, privacy treatments |
| Plexiglass art | Wall decor | Lightweight, backlit options | Scratch-prone, anti-static needed |
| Custom cabinetry | Kitchen, bathroom | Perfect fit, design control | Longer lead time, higher cost |
| Mosaic tile | Feature wall | Unique, durable, artistic | Grout maintenance, installation cost |
| Natural stone | Countertops, flooring | Timeless, heat resistant | Sealing required, can stain |
The CdA penthouse used a limited number of changes to completely modify the look and function of the two-story space. The architect designed and made all of the furnishings to create a warm and uniform environment. This integrated approach ensures that every element from the mosaic wall to the glass bathroom enclosure shares a consistent design language. Homeowners planning a similar transformation can draw on luxury penthouse design architectural features and premium materials to guide their material selections and spatial decisions.
