Converting a spacious apartment into a practical family home requires more than furniture shopping. It demands a strategic rethink of how every square meter serves the household. Modern families need spaces where cooking, eating, working, playing, reading, and sleeping coexist without conflict. The Prague apartment renovated by No Architects illustrates how thoughtful space reallocation can transform an overly monumental layout into a family-friendly environment. The process involves dividing large volumes into purpose-driven zones while preserving the openness that makes apartment living desirable.
Reimagining Layouts for Practical Family Living
Families moving into apartments with generous proportions often assume that keeping everything open is the best approach. Raw square footage does not automatically translate into livable space. A more effective strategy subtracts area from oversized rooms and converts it into dedicated zones for specific activities. This was the core approach in the custom residential redesign of the Prague apartment, where a portion of the living room was separated into a combined study, playroom, and guest room. By reclaiming that chunk of floor area, the family gained a fully functional room without diminishing the spaciousness of the main living zone.
Calculating Space Requirements for Each Family Activity
Before making any structural changes, measure how much space each daily activity actually needs. A dining area for a family of four requires about 8 to 10 square meters. A home office zone needs roughly 4 to 6 square meters for a desk, chair, and storage. A children’s play area functions well in 6 to 8 square meters. By mapping these requirements onto the existing floor plan, you can identify which rooms are oversized for their current use and could be subdivided.
The 60:40 Public-to-Private Ratio
A proven guideline in family apartment design allocates roughly 60 percent of the total floor area to private and service spaces (bedrooms, bathrooms, study, storage) and 40 percent to public zones (living, dining, kitchen). In apartments under 100 square meters, the public share can rise to 50 percent to maintain a feeling of openness. In the No Architects project, the living room originally occupied over 40 percent of the usable area. After reallocation, the public-to-private ratio shifted to a more balanced 45:55, creating room for a dedicated children’s zone and a home office.
Flexible Room Configurations with Sliding Partitions
The ability to reconfigure a room in seconds changes how a family uses its home. Sliding doors and movable partitions allow one space to serve as a playroom during the day and a guest bedroom at night. In the Prague apartment, large sliding doors disappear behind a bookcase, opening the study-playroom back into the living area when desired. This five-step approach to creating a welcoming home emphasizes flexible zones that adapt to changing daily needs rather than fixed room assignments.
Types of Movable Partition Systems
Different partition types offer different levels of flexibility, acoustic separation, and visual transparency. Choosing the right system depends on how often the room will be reconfigured and how much privacy each zone requires.
| Partition Type | Acoustic Rating | Space Needed for Storage | Best Use Case |
|---|---|---|---|
| Pocket sliding door | STC 30-35 | Wall cavity (100-150 mm) | Daily opening between living and study |
| Barn door | STC 20-25 | Wall surface (no cavity) | Bedrooms, bathrooms with limited wall space |
| Folding accordion wall | STC 25-30 | Stack at one side (200-400 mm) | Dividing a large room into two equal zones |
| Bookcase pivot wall | STC 30-40 | Rotation arc (full door swing) | Library wall that doubles as a room divider |
Pocket sliding doors offer the cleanest look because the door vanishes completely into the wall cavity. They require planning during construction or renovation since the cavity must be framed into the wall. Barn doors mount on the wall surface and work well in renovations where cutting into walls is not feasible, but they leave the door visible on the outside of the wall at all times.
Custom Furniture for Multi-Use Apartment Spaces
Off-the-shelf furniture rarely fits the specific dimensions and functional requirements of a subdivided open-plan layout. Custom-designed furniture allows each piece to serve multiple purposes. In the Prague project, the design team created a dining table and bench, a dressing room with valet stand and mirror, a kitchen with island, work desks, and play area furniture specifically tailored to the apartment and its occupants. Home renovations for guest-ready living benefit from this same approach, where every piece of furniture earns its place by serving at least two functions.
Tables That Do Double Duty
The dining table is the most versatile piece of furniture in a family apartment. It serves meals, homework, remote work, craft projects, and social gatherings. A rectangular table 1800 mm by 900 mm seats six people for dinner and works as a desk for two during the day. Tables with extendable leaves or drop-leaf designs allow the footprint to shrink when not in use.
Storage Walls as Room Dividers
A storage wall that runs from floor to ceiling serves two roles simultaneously. On the living room side, it holds books, media equipment, and display items. On the bedroom or study side, the same structure provides wardrobe space or shelving. The depth of a standard wardrobe (600 mm) is enough to create a visually solid partition while offering substantial storage. In multi-functional apartments, these dual-purpose walls eliminate the need for separate partition construction and separate storage furniture.
Technical Infrastructure in New Build Apartments
A good architectural design integrates technical infrastructure from the start. Heating elements, ventilation grilles for heat recuperation, closures and switchboards, metering equipment, and media connections must all be coordinated with the spatial layout. In new build apartments, the technical infrastructure is often already in place before the interior design begins, creating constraints that the design must accommodate. Compact urban site design faces the same challenge, where existing service runs limit layout options and require creative solutions.
Infrastructure Elements That Affect Layout Decisions
The position of heating risers, ventilation ducts, electrical panels, and data connection points determines which walls can be moved and where new rooms can be created. Moving a heating riser costs significantly more than working around it. A ventilation duct that runs through the middle of a proposed room may dictate the ceiling height or require a bulkhead that affects the visual flow.
| Infrastructure Element | Typical Cost to Relocate | Impact on Layout | Design Strategy |
|---|---|---|---|
| Heating riser | $1,500 – $4,000 | Cannot move through structural walls | Box in with cabinetry as a design feature |
| Ventilation duct | $800 – $3,000 | Reduces ceiling height where it runs | Integrate into bulkhead or dropped ceiling zone |
| Electrical panel | $500 – $2,000 | Must remain accessible at all times | Hide behind cabinet door in hallway or utility room |
| Data/network cabinet | $300 – $1,500 | Needs ventilation and access | Locate in storage room or under stairs |
The observant handling of these constraints often separates a well-executed apartment from a compromised one. Each technical element becomes a design opportunity rather than an obstacle when integrated properly into the overall scheme.
Creating Visual Cohesion Across Open Zones
An open-plan apartment with multiple functional zones risks looking disjointed if the visual language changes abruptly from one area to the next. A unified material palette ties the zones together. The Prague apartment used consistent flooring throughout including the bathroom, a strategy that visually expands each zone and makes the entire apartment feel larger. The same approach applies to wall colors, cabinet finishes, and lighting fixture styles. Understanding the architectural vocabulary of materials, finishes, and spatial terms helps homeowners communicate effectively with designers during this process.
Flooring Continuity as a Unifying Element
Running the same flooring material through the living area, kitchen, hallway, and even bathrooms creates a seamless visual plane. This requires careful detailing at thresholds and moisture barriers in wet areas. Polished concrete, large-format tiles, and engineered wood planks work well for continuous flooring because they handle both dry and wet zones with proper preparation. The Prague team chose a brushed concrete screed applied uniformly, which gave the apartment a raw, cohesive character that tied the open zones together.
Color Zoning Without Walls
When physical walls are removed, color becomes the primary tool for defining zones. A kitchen island painted in a contrasting color marks the cooking zone. A deep accent wall behind the sofa anchors the living area. A muted tone in the study corner signals a quieter activity zone. These color cues guide the eye and help family members intuitively understand where each activity belongs, without needing doors or partitions. The key is to limit the palette to three colors at most: one dominant neutral, one secondary tone for the main zones, and one accent color for feature elements.
The most successful family apartments in the architectural design vocabulary share a common DNA. They start with a clear understanding of how the family lives, they allocate space proportionally to activities, they use flexible partitions and custom furniture to maximize every square meter, and they integrate technical infrastructure rather than fighting it. The result is a home that grows with the family and adapts to changing needs without requiring a full renovation each time life shifts.
