Large and Narrow GI Tubes Clads The Facade of House 430/3 Designed by Nikhil Padgaonkar | NP Workshop | Goa

Nikhil Padgaonkar | House 430/3 For Natural Ventilation and Privacy | Goa | NP Workshop

Nestled in the village of Moira in North Goa, House 430/3 is a beautiful house designed by architect Nikhil Padgaonkar for himself, his wife and their 12-year-old son. The core requirement of the design was to avoid artificial air conditioning completely. Hence, the architect designed double-height volumes, created openings in the ceiling to dissipate warm air, and integrated screened facades comprising of a rhythmic alignment of large and narrow GI tubes that allow natural ventilation while preserving privacy. Further, the architect used a handful of materials -and a limited colour palette of browns and greys- when designing the property. Architect Nikhil Padgaonkar has shared more details about the project with SURFACES REPORTER (SR). Have a wonderful read:

Built between 2015 and 2019, House 430/3 is positioned at one end of a hill, allowing the dwellers a stunning view of the 380-year-old Church of Moira and fields beyond.

The sloping site offered the possibility of developing several terraces on which to site various programme components: the main house -a cuboid structure- sits at the highest level. At the same time, the lap pool, offices and garage have been assigned to the second level.

Cantilevered Balconies

The cantilevered balconies of the residence, extending two metres beyond the top level, give the impression of a structure grounded in the hill while simultaneously perched precariously above the pool. A small independent studio -below the pool deck- has been placed at the lowest level.


The main house comprises three bedrooms, two bathrooms, a living-dining space, a kitchen and a small office for Padgaonkar’s wife Lola, a Spanish photography critic and jewellery designer. 

Two Open-Air Patios For Ample Daylight

Creating two internal open-air patios around pre-existing trees allows every room to be open to the outdoors on at least two sides. This enables them to receive ample natural light while facilitating cross-ventilation.

Design Facilitates Natural Ventilation

A core requirement of the design was to entirely avoid artificial air conditioning, and the use of double-height volumes, openings in the ceiling to dissipate warm air, and screened facades comprising of a rhythmic alignment of large and narrow GI tubes that let cool air flow in while preserving privacy, serve as the primary mechanisms to meet this need. 


A Palette of Basic Materials And Muted Colours

Padgaonkar used only a handful of materials -and a limited colour palette of browns and greys- when designing the property: all ceilings are of exposed board-finished concrete, grey chuna (limestone powder paste) was used to finish the walls, and kadappa and brown limestone was used for the flooring. 


The large finely-pointed basalt stones from Bijapur in Karnataka for all outdoor walls, with masons brought in from the region to dress them, provide a recurring visual element while adding a sense of weight to the project. 

In order to limit the ingress of heat and glaring sunlight, the east and west facades of the house have been closed off with orange-brown kiln (refractory) bricks from Rajasthan, which typically line ovens and industrial chimneys. Their unconventional use in a residential programme brings a dash of colour to the otherwise subdued tones of the finishing.

Exposed black-tube conduiting and the metal-framed doors, shelves, stairs, and furniture were employed not merely for aesthetic effect but also as a pragmatic response to a moist climate and the ever-present threat of termites and white ants. 


The furniture and fittings were designed mainly by Padgaonkar himself, bearing in mind the need to house and display a large number of books and artwork he had inherited from his late father, a journalist of Goan ancestry who was delighted to see his son return to his roots.
