A 90-square-meter apartment presents a distinct set of design challenges that require careful spatial planning and material selection. The Silver Wave Apartment project in Kyiv demonstrates how thoughtful redevelopment can transform a cramped, poorly laid-out flat into a cohesive living environment that feels larger than its actual footprint. For homeowners and architects working with similar constraints, understanding how BHK configurations in apartment design influence spatial decisions is the starting point for any successful redesign. The key principles developed in this project apply to apartments of all sizes where the goal is to maximize usable space without sacrificing material quality or visual comfort.
Spatial Redevelopment Strategies for Limited Floor Plans
Before any aesthetic decisions are made, the spatial layout must be analyzed for inefficiencies. In the Silver Wave Apartment, the original layout suffered from three common problems: a separate kitchen darkened by a glazed balcony, a hallway that functioned as a narrow corridor with a chamfered corner, and a guest room and bedroom that shared identical dimensions. The redevelopment merged the hall, kitchen, and guest room into one continuous space. This approach, common among architectural terms used by architects, is called decompartmentalization and it directly addresses the issue of cramped urban apartments.
Identifying Underutilized Areas
Most apartments contain underutilized zones that can be reclaimed. Corridors, hallways, and transitional spaces often consume 10 to 15 percent of the total floor area without contributing to daily living. In a 90-square-meter apartment, this equates to 9 to 13.5 square meters of wasted space. By merging the hall with adjacent rooms, this area becomes part of the main living zone rather than a passage. The same principle applies to balconies and loggias, which in many floor plans are separated from interior spaces by doors and walls that block natural light.
| Space Type | Typical Wasted Area | Recovery Strategy | Usable Gain |
|---|---|---|---|
| Hallway/corridor | 8 to 12 sq ft | Merge with living or kitchen | Full area becomes usable |
| Chamfered corner | 3 to 6 sq ft | Custom cabinetry or seating | Transforms obstacle into feature |
| Glazed balcony | 15 to 25 sq ft | Sliding partition, thermal envelope | Seasonal living expansion |
| Identical adjacent rooms | Variable | Differentiated functions and finishes | Eliminates redundancy |
Redevelopment Planning Steps
A successful spatial redevelopment follows a structured sequence. Start with a measured floor plan and identify all load-bearing walls that cannot be moved. Then evaluate which non-load-bearing partitions can be removed or relocated. Prioritize merging spaces that share natural light sources. The Silver Wave Apartment used this approach to convert a dark separate kitchen into part of an open living area. The Architects Foundation scholarship for aspiring architects highlights how spatial problem-solving skills are a core part of architectural education and professional development.
Natural Material Selection and Textural Contrast
Material selection defines the visual and tactile experience of an apartment. The Silver Wave project centered its palette around natural textures: warm wood varieties paired with different types of grey marble against a backdrop of light-painted surfaces. The architectural dictionary of terms classifies this approach as textural juxtaposition, where contrasting materials create visual interest without relying on busy patterns or decorative embellishments.
Wood Selection by Room Function
One notable strategy in this project is the use of different wood species in different rooms. The bedroom incorporates dynamic American Walnut, which has pronounced grain patterns and rich brown tones that create a cozy, intimate atmosphere. The guest room uses tranquil toned oak, which offers a lighter, more neutral appearance that suits a flexible multipurpose space. This room-specific material differentiation helps each space establish its own character while maintaining overall visual harmony. Each wood species was selected for its natural grain structure rather than stained or painted finishes.
Natural Marble as a Centerpiece
The centerpiece of the interior is a large Silver Wave marble panel. Natural marble forms over millions of years through the compression of limestone under heat and pressure. Each slab is unique, with veining patterns that cannot be replicated. Using a single large marble panel rather than multiple smaller pieces creates a focal point that anchors the entire interior. The marble appears in the main living area where it catches changing light throughout the day, shifting the room’s appearance from morning to evening.
Open-Concept Layouts and Room Merging Techniques
Merging rooms requires attention to sight lines, traffic flow, and functional zoning. In the Silver Wave Apartment, the merged hall, kitchen, and guest room created a single L-shaped living area approximately 50 square meters in size. This open layout allows natural light from the balcony to reach deeper into the apartment. The kitchen counter and island define the cooking zone without enclosing it. The copyright and design rights in construction projects cover these architectural plans, so homeowners should understand what ownership means when commissioning custom apartment redesigns from architecture firms.
Zoning Without Walls
In open-concept layouts, furniture placement and floor materials define zones. The kitchen area uses marble flooring that transitions to wood in the living zone, creating a visual separation without a physical wall. Area rugs further define seating zones within the living area. Lighting zones follow the same pattern: pendant lights over the kitchen island, recessed cans in the circulation path, and a floor lamp in the seating area. Each zone uses its own light source to reinforce the spatial division.
Flexible Space Division with Glass Partitions
The Silver Wave Apartment addresses the tension between open living and the need for private outdoor space through a sliding glass partition separating the kitchen from the loggia. This solution gives the homeowner control over the space: when the partition is open, the loggia functions as an extension of the kitchen; when closed, it remains a private balcony for summer use. The Rockville housing historical architecture meets modern residential design project demonstrates a similar principle, where historical building envelopes are adapted with modern interior partitions to create flexible living arrangements.
Partition Selection Criteria
Sliding glass partitions require several considerations. The glass must be tempered for safety, typically 8 to 10 millimeters thick. The frame material affects thermal performance: aluminum frames with thermal breaks minimize heat transfer between interior and exterior zones. The track system should use smooth-rolling bearings to ensure easy operation, especially for partitions wider than 6 feet. Full-height partitions from floor to ceiling create the cleanest visual line and avoid the chopped appearance of half-height dividers.
| Partition Type | Glass Thickness | Frame Material | Thermal Performance | Best Use |
|---|---|---|---|---|
| Single sliding panel | 8 mm | Aluminum with thermal break | Moderate | Balcony to living room |
| Multi-panel folding | 10 mm | Aluminum or steel | Good with weatherstripping | Large openings, patio access |
| Pivot door partition | 10 mm | Steel frame | Good | Room divider, study nook |
| Fixed glass wall with door | 12 mm | Frameless or minimal frame | Excellent | Permanent light-admitting divide |
Lighting Design for Compact Living Spaces
Lighting in a small apartment must serve multiple functions: ambient, task, and accent lighting all within the same square footage. The Silver Wave Apartment uses a layered lighting approach. Recessed ceiling lights provide general illumination, task lighting appears over work surfaces and reading areas, and accent lighting highlights the marble panel and other material features. Maximizing natural light is equally important. Removing walls between the kitchen and living area lets sunlight travel through the apartment, reducing the need for artificial lighting during daytime hours. The attic apartment conversion guidelines address similar lighting challenges, particularly the need for skylights and light wells in spaces that lack exterior wall exposure.
Light Temperature and Material Interaction
The interaction between light temperature and material color affects how a space feels. Warm light at 2700 to 3000 Kelvin enhances the richness of American Walnut and creates a welcoming atmosphere in the bedroom. Cooler light at 3500 to 4000 Kelvin complements the grey marble tones in the kitchen and living area, making the space feel crisp and clean. Dimmable fixtures allow homeowners to adjust the lighting mood throughout the day. A lighting plan should specify color rendering index values of 90 or higher to ensure that natural material textures appear accurate and vibrant under artificial light.
Reflective Surfaces for Light Distribution
Glossy and reflective surfaces help distribute light in compact spaces. The marble panel’s polished surface reflects both natural and artificial light, brightening the surrounding area. Mirrors placed opposite windows double the apparent amount of incoming daylight. Glass-fronted cabinets on upper walls create depth without blocking light penetration. These strategies are particularly effective in apartments where window area is limited by building structure or exterior design constraints.
