Plinth is a brokerage run by architects. We sell a short list of homes in Mumbai, Goa, Bengaluru and Pune, each presented as a case study, with drawings, diligence and an advisor who has walked every room.
(01) The studio
We started as an architecture practice in 2011 and became a brokerage by accident: clients kept asking us to sell the homes we had restored. We still read a building structure first, lobby last, and we still say no to most listings we are offered.

Each residence is documented the way an architect would present it: drawings, structure, light, and the honest list of what we would change.
(Founder) Ira Castellino, B.Arch, 2004(04) About the founder
An architect
who sells homes
“A listing tells you the carpet area. A drawing tells you whether the kitchen will get morning light in December. We sell from the drawing.”
Ira Castellino trained as an architect in Mumbai and spent seven years restoring Bandra bungalows before opening Plinth. She still reviews every mandate personally and walks each residence before it enters the index.

(08) Clients
In their words
“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.”
“Our Pali Hill townhouse sold in eleven days, to someone who had read the restoration drawings. That never happens.”
“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.”
“We relocated from Bengaluru to Pune with two children and a dog. Meera knew which society would welcome all three.”
“Tara found us a monsoon lease in Assagao with fibre internet and a real desk. Best working year of my life.”
“Farhad told us not to buy on the 41st floor and explained why with the society minutes. We bought on the 28th. He was right.”

Read the floor plan before the listing
Photographs sell a mood. Plans tell you how a home will actually be lived in. Here is how we read one.

(01)How do I book a site visit?
Open any residence and choose a date and an hour in the visit panel, or use Book a visit in the menu. Slots that are already taken are greyed out. Your advisor confirms by phone or WhatsApp within a working day.
(02)What is the reservation amount and is it refundable?
To take a home off the market while diligence runs, you can pay a reservation online. It is 0.1% of the asking price (between ₹25,000 and ₹2,00,000) for sales, and half a month's rent for leases. It is fully refundable for 14 days and is adjusted against the token amount in your agreement.
(03)What does the Plinth Diligence File cover?
Title search, approvals and occupancy certificate, society minutes and dues, a structure note from our architect and a tax summary, reviewed by counsel. It is shared with you before you sign anything binding.
(04)What are your fees?
For buyers, 1% of the transaction value plus GST. For sellers, 1% to 2% depending on the mandate. For leases, one month's rent from each side. New-launch purchases carry no fee for buyers.
(05)Can you help me sell or lease my home?
Yes. Request a free valuation on the Sell page. An advisor visits within a week, measures the home for a Plinth floor plan and shares a written pricing view.
(06)Do you work with NRI buyers?
Often. We run video site visits, coordinate power of attorney and work with your bank on NRE/NRO payments and repatriation paperwork.
