Compact Apartment Design with Flexible Layout: MM33 by buno in Bangkok

Rethinking Urban Domesticity through Spatial Economy

Located in Bangkok's Khet Khlong Toei district, the MM33 Apartment designed by buno challenges the standardized commercial logic of apartment planning with a compelling experiment in compact apartment design with flexible layout. Rather than adhering to market-driven room proportions, this 54 m² renovation reorients the spatial logic around the human scale, usability, and adaptability, crafting a more generous sense of space from minimal square footage.

Deconstructing the One-Bedroom Box

In a typical urban housing unit, walls dictate function and fixed boundaries define use. MM33 subverts that paradigm. The design eliminates rigid room enclosures and instead disperses functional zones—sleeping, dressing, bathing, and lounging—along the edges of the apartment. This gesture creates a central “court,” a flexible and visually open area that simultaneously operates as the kitchen and dining space while serving as the apartment’s spatial and visual core.

The result is an open-plan layout where the perception of space far exceeds the apartment's compact footprint. The use of minimal fixed boundaries not only maximizes openness but also redefines privacy as a flexible and user-controlled condition.

Operable Walls and Adaptive Furniture Systems

Privacy and spatial division in MM33 are addressed not through construction but through operability. Movable curtains and sliding partitions replace solid walls, giving the inhabitants the ability to tailor the environment according to their needs. These operable systems allow the space to function dynamically throughout the day and across different life scenarios.

Integral to this flexibility is the concept of the furniture-as-architecture. Every built-in piece—from the kitchen fixtures to the wardrobe units—functions as an independent prefab module. Constructed from clear-coated structural plywood, each unit is visually expressive, revealing the raw material layers and celebrating simplicity without monotony.

These modules are not only efficient in form but act as tactile interventions that replace the traditional architectural roles of walls or columns, adding both structural rhythm and utility.

Materials that Define Space without Dominating It

Material honesty is key to MM33’s ambiance. The flooring, a soft matte beige linoleum, provides a light and continuous surface that avoids visual fragmentation. The joinery and built-ins, rendered in raw plywood with visible striations and grains, offer subtle texture and color variation. These material choices soften the strict geometries and amplify a sense of warmth and craft.

Color is used not to decorate but to differentiate spatial functions. Subtle tonal shifts between modules break the box-like feel and bring clarity to spatial organization. This restrained yet expressive palette also ensures that furniture additions and personal artifacts integrate naturally without clashing against a dominant aesthetic.

A Scalable Model for Urban Living

What makes MM33 truly innovative is its potential as a replicable model. The compact apartment design is not bound to this single location; rather, the use of prefab modules and the flexible layout concept can be applied across various sites and urban conditions. In cities where housing is increasingly limited by both space and budget, this model offers a dignified, livable, and aesthetically considered alternative.

Through deliberate reduction, operable boundaries, and thoughtful prefab detailing, buno presents MM33 as a new paradigm for compact urban living. It is both a design of necessity and of ambition—proving that architectural intelligence and material honesty can create freedom, even within 54 square meters.
