Carpentry solutions, built-in doors, and integration with kitchens and balconies are transforming compact laundries into discreet and sophisticated spaces within small apartments. Recent projects show how architecture and organization can hide machines, sinks, and clotheslines without compromising functionality, ventilation, and circulation.
The reduction in apartment sizes in São Paulo has directly influenced how architects design service areas, transforming the laundry room into an integrated part of the decor, rather than just a technical space separate from the rest of the house.
In compact units, solutions such as bifold doors, multifunctional cabinets, built-in clotheslines, and integrated countertops help hide washing machines, sinks, and utensils, maintaining practicality in daily use without compromising circulation, lighting, or the sense of spaciousness in the rooms.
Recent data from Secovi-SP shows that properties up to 45 m² continue to be among the most common formats in the São Paulo market, a scenario that drives the demand for projects capable of making better use of every available square meter within apartments.

In this context, units between 30 m² and 45 m² are among the most representative in new launches and sales, reinforcing the demand for flexible, functional, and visually integrated environments that fit the residents’ routine.
Compact laundries gain space in small apartments
Among the most used rooms in the house, the laundry room combines functions that require ventilation, storage, circulation, and support area, making planning essential to avoid blockages in the use of the machine, cabinets, or cleaning products.
According to architect Daniella Martini, from Pro.a Arquitetos, the absence of an exclusive laundry space has become frequent in compact apartments, especially in more recent projects aimed at residents living alone or as a couple.
Even when the condominium offers a communal laundry room, many residents still prefer to keep at least the washing machine inside the apartment, as this facilitates their routine and reduces dependence on shared areas during the day.
For Luis Rossi, Nicolas Le Roux, and Paula Lemos, from COTA 760 Arquitetura, the minimum width for a functional laundry room usually starts at 1.3 meters, a measurement considered sufficient to accommodate a sink and washing machine without compromising circulation.
Secret doors and carpentry help hide the laundry room
In current projects, kitchens, bathrooms, living rooms, and terraces have begun to share space with the service area, requiring more discreet solutions to prevent equipment and cleaning products from visually interfering with social environments.
Therefore, the most used strategy by architects is to integrate plumbing points and appliances into the carpentry, using doors that conceal the laundry room when it is not being used by residents.
According to architect Rafael Zalc, embedding the laundry room in cabinets near the kitchen or terrace has become a recurring alternative in compact properties with few possibilities for physical division.
“Bifold doors allow the entire unit to be fully opened during use and closed afterward, maintaining the visual unity of the environment,” he states.
While kitchens and living rooms usually receive priority in window distribution, laundry room ventilation needs to be solved with resources capable of preventing humidity, mold, and difficulty in drying clothes.
In this scenario, elements such as cobogós (perforated blocks), louvers, ventilated doors, and retractable clotheslines help improve air circulation and also contribute to preserving the visual integration between the apartment’s environments.
In addition to ventilation, the choice of materials also directly interferes with the functionality of the space, especially in small apartments where the kitchen and laundry room end up sharing the same visual composition.
Resistant coverings, easy-to-clean countertops, uniform lighting, and well-sized cabinets make the routine more practical, especially when the service area needs to remain integrated into the social environments of the residence.
Most common mistakes in compact laundries
Lack of planning remains among the most common mistakes in compact laundries, especially when equipment, cabinets, and climate control systems are installed without considering circulation, ergonomics, and daily use frequency.
When air conditioner condensers, heaters, machines, and cabinets occupy the same area without proper organization, the space loses functionality and becomes even more limited for simple daily household activities.
According to architect Bruno Borges, from BSB Arquitetura, an excess of equipment in small environments reduces space efficiency and hinders both movement and the organization of everyday items.
For this reason, the project needs to clearly define what should remain visible, what can be hidden, and which objects can be transferred to cabinets in other parts of the apartment.
Organization has also become an important part of aesthetics in compact areas, especially in integrated projects where any visual excess directly interferes with the feeling of comfort and spaciousness.
Cleaning products grouped by use, organizing boxes, vertical niches, and high shelves help free up counter and floor space, while the built-in clothesline prevents clothes from visually occupying the entire integrated area.
Projects show solutions for kitchens, bathrooms, and balconies
In a 49 m² apartment, the integration between bathroom and laundry was used to better utilize every available centimeter without compromising visual comfort or hindering the simultaneous functioning of the environments.
In this project, the joinery combines a countertop, sink, cabinets, and a built-in clothesline, while the washer-dryer concentrates operations in a single point, facilitating daily use in a reduced area.
In a 59 m² property, the laundry was incorporated into the kitchen through a countertop that combines a sink, utility tub, and washing machine within a continuous and visually discreet composition.
At the same time, terracotta ceramic tiles delimit the service area without causing an abrupt break between the environments, preserving integration and creating a smoother transition between the functions of the space.
In another project, reconfiguring the layout allowed for expanding the laundry room and bringing it closer to the kitchen, making better use of natural light and improving circulation between the integrated environments.
With the use of cobogós (hollow elements), natural lighting began to reinforce the feeling of spaciousness and ventilation, a characteristic considered important in properties with reduced square footage and few side openings.
There are also proposals where a continuous porcelain countertop connects the kitchen and laundry within a uniform aesthetic, hiding part of the technical area without interrupting the apartment’s visual composition.
In this type of solution, a sculpted sink, appliance tower, and closed joinery help conceal the equipment, creating a cleaner result aligned with current trends in compact interiors.
In a 21 m² balcony, the strategy was to combine a bar, laundry, and domestic support in a metalwork cabinet designed to alternate functions according to the residents’ needs.
With the bi-fold door, the equipment can remain hidden during social gatherings and only appear during laundry use, preserving the aesthetic of the property’s outdoor area.
Light colors and visual integration help enlarge environments
The choice of colors has also become important in integrated laundry projects, especially in small apartments where any excessive contrast interferes with the visual unity of the environments.
In a 58 m² apartment, the combination of green joinery, stainless steel appliances, and natural elements helps soften the presence of the service area and reinforces the feeling of aesthetic continuity.
On the other hand, some compositions opt for black cabinets, countertops, and equipment to create a uniform aesthetic capable of better disguising the laundry within the integrated kitchen.
Even when using dark tones, metallic accents and light surfaces help balance the visual ensemble, preventing the environment from feeling heavy or excessively enclosed for compact apartments.
In properties that prioritize brightness, soft tones and fluted glass doors appear as an alternative to separate environments without blocking the entry of natural light into the apartment.
In a 70 m² project, the sliding door with fluted glass delimits the laundry integrated into the kitchen and preserves natural lighting even with the partial division of spaces.
The same logic appears in proposals with a rustic or contemporary aesthetic, where natural materials help to soften the presence of the service area within shared environments.
Wood, soapstone, countertop sinks, checkered tiles, and exposed metals can be used as long as they resist humidity and do not hinder the daily cleaning of the spaces.
With smaller apartments and more dynamic routines, the laundry room stopped functioning as an isolated room and began to play a strategic role in interior design projects aimed at compact properties.
When well-planned, the service area can preserve circulation, hide equipment, and maintain daily practicality without compromising the aesthetics of integrated environments.
