The Gritted Grid

[English text below] Berlokasi di pojok lahan di kawasan Tebet, Jakarta Selatan, The Gritted Grid merupakan rumah hasil renovasi yang menyatu dengan lingkungan sekitarnya, namun tetap tampil menonjol melalui identitas arsitektur yang kuat. Elemen paling mencolok dari rumah ini adalah fasad berbentuk grid yang dibuat dari breeze-block berbahan fiber semen khusus, membungkus tiga sisi bangunan. Grid ini bukan hanya menjadi inspirasi nama rumah, tapi juga memainkan peran penting dalam cara rumah ini bekerja dan terasa.

Fasad bergaya grid tersebut berfungsi seperti lapisan kedua pada bangunan. Ia menjaga privasi dari arah jalan, meredam panas, serta memungkinkan cahaya alami dan udara segar masuk ke dalam rumah. Di saat yang sama, ia membingkai pandangan ke arah taman dan langit, menciptakan hubungan langsung dengan alam tanpa kehilangan rasa tertutup. Sepanjang hari, bayangan cahaya matahari yang menembus grid menciptakan gerak dan dinamika pada permukaan bangunan.

Proses renovasi mempertahankan sebagian struktur lama, namun tata ruangnya ditata ulang agar lebih sesuai untuk keluarga besar lintas generasi. Kamar tidur untuk orang tua lansia ditempatkan di lantai dasar demi kemudahan akses, sementara kamar anak-anak berada di lantai atas. Meskipun fungsi rumah ini beragam, alur ruangnya terasa menyatu, dengan area bersama di bagian tengah dan ruang pribadi di sisi-sisinya.

Bentuk bangunan dirancang agar terasa lebih ringan dan terbuka dibandingkan rumah dua lantai pada umumnya. Bagian struktur yang ditinggikan dan penggunaan material berpori membuat bangunan terasa tidak berat secara visual sekaligus lebih nyaman dihuni. Setiap kamar memiliki kamar mandi dan area luar ruang sendiri, fitur yang sangat berguna selama masa pandemi karena memungkinkan isolasi mandiri tanpa membuat penghuni merasa terasing.

The Gritted Grid memperlihatkan bagaimana desain yang dipikirkan dengan matang bisa menjawab kebutuhan sehari-hari—menjaga keseimbangan antara privasi, keterbukaan, dan keindahan. (uci)

The Gritted Grid

Located on a corner lot in Tebet, South Jakarta, The Gritted Grid is a renovated house that blends into its neighborhood while standing out with a bold architectural identity. Its most striking feature is the grid-like façade made from custom fiber cement breeze-blocks, which wraps around three sides of the house. This grid not only gives the home its name but also plays an important role in how the house works and feels.

The gridded façade acts like a second skin. It protects the house from street views, keeps the heat out, and allows natural light and air to pass through. It also frames views of the garden and sky, creating a connection with nature while still giving privacy. Throughout the day, the sun casts shadows through the grid, bringing life and movement to the building’s surface.

The renovation keeps parts of the original structure but reworks the layout to better suit a large, multi-generational family. Bedrooms for elderly parents are placed on the ground floor for easy access, while the second floor houses rooms for the children. Even though the house serves many needs, the layout feels connected, with shared spaces in the middle and private rooms on the edges.

The building’s form is designed to feel lighter and more open than typical two-story houses. By raising parts of the structure and using breathable materials, the design reduces bulk and improves comfort. Each bedroom has its own bathroom and outdoor space, which became especially useful during the pandemic, allowing family members to isolate if needed without feeling cut off.

The Gritted Grid shows how thoughtful design can respond to everyday needs—balancing privacy, openness, and beauty. (uci)
