who broker

Plinth began as a two-desk architecture practice. Today it is a brokerage of fourteen people across four cities that still thinks like one.

(01) Story

We were restoring a Pali Hill townhouse in 2014 when its owner asked us to sell it. We wrote a twelve-page document about the house, its structure, its light and its faults, and it sold in eleven days. Every listing since has been written the same way.

We take on fewer homes than a conventional brokerage and turn down most of what we are offered. In exchange, every residence in the index has been walked by an architect, documented with measured plans and checked for title, approvals and structure before a buyer sees it.

“Most homes are sold by people who have never read the drawings. That is the whole of our advantage.”

Seven years restoring Bandra bungalows taught Ira how buildings age. She still reviews every mandate personally and walks each residence before it enters the index.

  1. 2011An architecture studio in Bandra

    Ira Castellino opens a two-desk practice above a bakery on Pali Mala Road, drawing restorations for Bandra's old bungalows.

    A client asks the studio to sell the townhouse it restored. It goes in eleven days, to a buyer who read the drawings first.

    Plinth registers as a RERA brokerage and hires its first advisors: an architect, a surveyor and a lawyer, before any salespeople.

    Alibaug land and Assagao villas join the book, with a title-first process that becomes the Plinth Diligence File.

“They sent us a floor plan with three walls circled and a note: these are the only ones you can't move. We bought the house because of that note.”

“Kabir walked the boundary of our Alibaug plot in the rain and found the one problem the seller had not mentioned. Worth every rupee of the fee.”
