With Exposed Block Structure and Simple Foundation, the Construction of This Brutalist Kitnet of 30 m² Only Costs R$ 25 Thousand to Build, Achieving Higher Profitability Than Traditional Financial Investments and Attracting Investors Seeking Low Cost and Quick Returns in the Real Estate Market
The proposal for this 30 m² brutalist kitnet only costs R$ 25 thousand to build and is based on a concept of technical simplicity, viable even for those without construction experience. The project uses about a thousand structural concrete blocks, a shallow foundation in a radier, and mixed finishes between exposed surfaces and plastered walls, resulting in a minimalist aesthetic and low maintenance.
The brutalist look is achieved by keeping part of the blocks exposed and applying plaster only in strategic areas. The construction is fast, clean, and economical, with reduced labor and an average execution time shorter than conventional projects. This combination of low investment and speed makes the property have a high potential for financial return, especially in medium-sized cities and university hubs.
Step-by-Step Construction Technique
The work starts with soil preparation and the execution of the radier, a reinforced concrete slab with steel mesh and gravel layer, which eliminates the need for footings or piles in stable soils.

This is the cost to build a simple 60 m2 house in 2026, including contingencies, foundation, finishing, labor, and hidden fees.
On this base, vertical rebar – the so-called “needles” – are positioned, serving as anchoring for the 14 x 19 x 39 cm block walls.
The wall raising follows a modular and precise rhythm, with alternating rows of solid blocks and channels, filled with steel and concrete. The lintels and headers for doors and windows are shaped within the masonry itself, optimizing material use.
On the 14th row, a continuous upper beam is formed, distributing the weight of the joist slab, EPS boards, and concrete. The result is a solid, thermal, and functional structure, with no waste of materials.
Functional Finish and Brutalist Aesthetics
The upper part of the construction receives a parapet of three additional rows of blocks, which houses the water tank and gives a modern finish to the façade.
The roof consists of metal trusses, central gutter, and a gable roof, designed for efficient rain runoff and simple maintenance.
Internally, the space combines practicality and comfort. The interior walls are plastered and smooth, while the flooring varies according to the area: burned cement in the social area, ceramic in the bathroom and laundry, and laminate in the bedroom.
The windows and doors feature subtle frames and metal drip edges, protecting against leaks and enhancing the durability of the ensemble. The concept is to maintain an industrial and clean look, balancing economy and architectural identity.
Compact Layout and Maximum Utilization
With only 30 m², the brutalist kitnet has been designed to comfortably accommodate two people. The layout integrates living room and kitchen in an open format, allowing for cross ventilation and natural lighting.
The living room accommodates a sofa and television, while the kitchen includes counter, sink, stove, refrigerator, and dining bench.
In the back, there are the bathroom, laundry with tank and washing machine, and the couple’s bedroom with built-in wardrobe.
The utilization of every square meter is the project’s differential, reducing circulation areas and prioritizing integration. Even with reduced dimensions, the final result is a functional, well-lit, and easy-to-maintain space.
Profitability Above the Financial Market
The estimated total investment of R$ 25 thousand to build makes the kitnet a high-yield asset. In areas with rental demand, the monthly return can exceed 2% of the invested amount, surpassing average earnings from CDI, LCI, LCA, and even the Selic rate.
In comparative terms, a unit can generate annual yield exceeding 24%, considering continuous occupancy and preventive maintenance.
This performance attracts small investors and freelancers seeking real alternatives for asset appreciation with controlled risk.
The structural simplicity and material durability ensure low maintenance costs and long-lasting durability, making the project feasible for both rental and resale.
The 30 m² brutalist kitnet that only costs R$ 25 thousand to build represents a synthesis of efficiency, aesthetics, and profitability.
The model combines low cost, rapid execution, and architectural appeal, becoming one of the most attractive options in the micro-housing market in Brazil.
Would you invest in a low-cost brutalist kitnet like this to ensure a higher monthly income than traditional financial investments?
