Architects: Alan Chu & Cristiano Kato
Location: Ilhabela, Sao Paulo, Brazil
Project year: 2008
Site area: 8,000 sqm
Constructed area: 36 sqm

It is a small construction with an equally simple program:

A caretaker’s house of a property on an island on the North coast of the State of São Paulo, Brazil.

The site, at 100 meters above sea level, next to two enormous rocks, already had the old caretaker’s house, one-story house with walls and clay roof tiles.

Original House


The new building has 2 floors, a white suspended box, where the bedroom is and it is possible to see the continent and the São Sebastião Channel. Under it, at street level, are the living room, kitchen and bathroom.

The wood used on some doors and windows, staircase, shelves and furniture are leftovers of material used to make scaffoldings and molds for the white box reinforced concrete structure.

The 3.00 m x 5.00 m white box is supported on one side by an existing retaining wall and on the other by a wall built with stones, a characteristic of local constructions.

section 03

This movement shapes the other 3 spaces of the construction, the access yard, between the box and the retaining wall that curves following the parking lot ramp’s floor, the courtyard, between the box and the rock and the void created under the box, where the living room is.

The impact caused by the image of concise volume, in comparison with the large rock’s amorphous exuberance, gives it a strange sensation.

During the work, the caretaker Zé Maria, still not content with his future living quarters, compared it with a can of sardines, a container as those he sees passing through the channel or even a cooler, like those used by beachgoers to carry beer.

    This is a cute little project. I love small scale design.

    Architecture that plays off of the contrasts between nature, the plasticity of materials like concrete, and stone texture will never go out of style. These are the lessons taught, in particular, by Walter Gropius.

    This is particularly a nice project because it is so concise, not quite the intellectual rigor of the Cabanon but perfectly wonderful. The kitchen living space and its use of recycled materials is absolutely spot on.

    One of my favorite projects on Arch. Daily in a long time.

      You could have just said “One of my favorite projects on Arch. Daily in a long time” and that would have been sufficient. Douche.

      • T

        You’re so mature.

  • sko

    nice photo!

  • Benjamin

    I’d much prefer the old house rich with its history to stay there… now there is no trace of what used to be… sad

    • mvb

      If the client wanted to continue living in the old house, he had not hired any architect.

      • AW

        The person living in the house isn’t the client. It’s the client’s groundskeeper. And according to the article, he doesn’t like the house at all.

  • AAA

    here someone put a TV over the history a place, the old house was much better than the new, the TV could be in any place less than this.
    it’s a nice volum but, i’m sorry i think your kill a peace something.
    i agree bejamin SAD.

    Very nice. Best box in a long time. The interiors open up to the outside spaces very beautifully and the ground level stone wall acts as a good reference to the old structure.

  • Partick Bateman

    Beautiful, i absolutely love this.
    So simple and elegant, the juxtapostition of materials is excellent. LOVE IT!!

  • Rokas

    Agree with Partick,disagree with Benjamin.
    Even if its old and “warm”,still-would you like to live in the house which have 10 squere metres?Havent tried?If so-dont speak so nostalgically abouth the past.The junctaposition bentween the past,”natural”elements, and the new one was worth to do :D

  • heath

    i am really sad about this project.
    i think the old house is much more better than the new one.

  • mike

    “old house is much more better than the new one”

  • Tyler

    yes mike,
    we need to preserve ancient structures that are inefficient, and would probably cost more to rennovate than just tearing down and starting over. duh….

    p.s. i believe the foundation was preserved or at least the footprint, and i assume keeping traces of the original structure was kept in mind when designing the new house.

  • majchers

    Great project. Congratulations to the designer(s). I can not wait till it ages and blends in with the rock the way the old one was.

  • Benjamin

    …so ur telling me the architect wasn’t good enough to increase the living area of the house and interiors but also keep the existing history of the old structure too… possibly they needed a more experienced architect on the job

  • alejandro

    It is a great project now… but in a few years, it will be beautiful

  • Troy Lemieur

    Haha… Tyler, awesome comment. Sooooo true.
    Benjamin – have YOU tried living in that small of a space? Many people have different lifestyles. Some people spend most of their time away from home, (off the computer), and are only in their homes to sleep, groom, and eat.
    I actually admire the preserve it takes for one to live in such minimalist conditions. It has the potential to be a great thing.
    The reason this got past the drawings and actually built was because the client approved them. He obviously knew what he was getting.

  • Phillipe Donato

    Amazing project , perfect integration with the beautiful landscape . I really like living in such a minimalist space. It’s more than a lifestyle its an ideology.

  • Rokas

    I think,Benjamin,if there was any possibility to preserve the existing structure,the client (I think),maybe wished the same thing as you.But-sad but true-in my own practice-such structures cant hold anything-they are like the paper bags-holds their weight till you dont touch them.:(

  • Jeison

    This house is located in Ilhabela, so it´s probably a weekend home, not intended for permanent living…

  • Carl

    Only negative thing I can imagine is that the caretakers income probably is 1/100th of the expenses put into the building.

  • majchers

    No doubt the old house had its own charm (just this small cannon alone is a marvel) but what the architect did here is one of a kind creation and a beauty on its own! Congrats again guys. I love it!

    Withut disturbing Gropius, I cannot do without saying that this is pure and crazy bullshit… no one will ever be able to convince me that a ugly CUBE OF CONCRETE crapped in a beautiful and wild environment is “simple and elegant”.. but are you crazy or what? A CUBE OF CONCRETE is a “particularly a nice project”??? …and may be the people around you think that you are a sentient being… of course, whenever you’re not full of dope…

  • Arturo

    Certainly “The new” just for the sake of it is not good, but also de old just because exists doesn’t make it better. but my main concern is on the last part of the description

    “compared it with a can of sardines, a container as those he sees passing through the channel or even a cooler, like those used by beachgoers to carry beer.” so what the purpose of architecture that doesn’t serves the person, it certainly a beautiful design and a very clever use of the space but then… is the person’s opinion irrelevant?

    Maravilhoso! Um casulo (cápsula) de morar!
    Um dos projetos mais fantásticos que vi nos últimos tempos…
