Gaurav Roy Choudhury Architects Erects Lightweight Steel “Scaffold” in the Central Core of This Bangalore Home | Renovation Project


Gaurav Roy Choudhury Architects (GRCA), which is the eponymous firm of architect Gaurav Roy Choudhury, renovated a low-cost project in Bangalore. The practice has converted the original building that was built on a square 60'x60' corner site with three apartments into two duplex houses. The house is named Scaffold house as the firm erected lightweight steel 'scaffold' of 2"x2" mild steel box sections in the central core of the house. The idea of the Scaffold house stems from a pragmatic approach towards renovation, clarifying the understanding of the 'new' in context to the 'old'. Architect Gaurav Chaudhary has shared with SURFACES REPORTER (SR) more details about the project. Have a look:

The original load bearing building was a retirement home of the client. The format of the house came into question once their son moved to Bangalore. A reconsolidation of the house was needed.


Structure, site and budget concerns needed a bold intervention which changed the project from a finicky renovation to one of a motivated architectural intervention in that of making a family house.

Changes in the Central Core Design

A square of 20'x20' in the centre of the building was broken down carefully becoming the central core for this intervention. This space became the volume catalyzing the restructuring process.

Since periphery of the building had most of the existing functions, they were mainly retained with very limited intervention.

A light weight steel 'scaffold' of 2"x2" mild steel box section was erected in this central core space as it became the language of the new as it negotiated with the old.


This framework also acted as a structural tie for the existing structure as it held it in place. The walls of the existing house were slowly and carefully reconfigured to enable this transformation as well.


The staircases, passages, gardens, and circulation spaces came into this central space, including an AV room and a terrace sit-out.

Cross Ventilation and Interplay of Light and Shadows

A light translucent sheet above the central core gets bright sunlight into both the houses, as it also enables cross ventilation for the peripheral spaces.


The shadows of the steel scaffold, as they move through day animate the houses with the changing light and seasons giving a living pulse to the houses.

The steel scaffold showed up externally as well, to extend the living spaces into beautifully activated gardens in the west and the south road facing facades.


The compound walls were raised and grilled above, to include these gardens into the privacy and security of each house.

The southern part which occupied more space on the ground became the parents' house while the northern part which grew as it went higher became the son's house.


The Scaffold House is an ambitious and pragmatic project ensuring that it maximizes its impact without getting sucked into a dark spiral which plagues most renovation projects.
