⚡ Quick Answer

To book a flat at L&T The Gateway Sewri: verify the MahaRERA registration (P51900054969), choose your unit, submit the booking form with KYC documents and the booking amount, receive the allotment letter, then sign and register the agreement for sale after paying stamp duty. Under RERA, the developer cannot take more than 10% of the cost before a registered agreement.

  • Pay only to the developer's official bank account, never in cash or to a personal account.

  • Read the cancellation terms before you sign the booking form.

Once you have seen the project and chosen a home, the booking stage begins. It involves a few forms, some payments and important legal documents. Knowing the steps in advance helps you move quickly on the unit you like – without missing any checks.

This guide walks you through how to book a flat at L&T The Gateway Sewri, from the checks to make before you pay to the registration of your agreement for sale.

Before You Book: Checks to Make

Step 1: Choose Your Residence

L&T The Gateway Sewri offers three residence types:

ResidenceCarpet area (sq.ft)Carpet area (sq.m)
3 BHK1,00092.90
4 BHK1,905176.98

Carpet areas as shared by the developer. Your exact unit area will be in the agreement.

Not sure which size suits your family? Compare them in 3 BHK vs 4 BHK vs 4.5 BHK, and check room-by-room layouts in the floor plans and carpet area guide. The L&T The Gateway Sewri brochure also shows typical plans for each type.

Step 2: Booking Form, KYC and Booking Amount

To reserve your unit, you fill in a booking (application) form and pay the booking amount. Ask for the current booking amount for your unit, as it is set by the developer. Documents usually needed:

  • Identity - PAN card for every applicant, plus Aadhaar or passport.
  • Address proof - Aadhaar, passport or a utility bill.
  • Photographs - recent passport-size photos of all applicants.
  • For NRIs - passport, visa or OCI card, overseas address proof and NRE/NRO bank details. See the NRI guide to buying a flat in Mumbai.
  • For joint buyers - documents of each co-applicant. See joint home ownership in Mumbai.
Important: pay by cheque, demand draft or bank transfer only to the account named by the developer, and keep every receipt. Never pay in cash or to a personal account.

NRIs who cannot travel can authorise a family member in India – read Power of Attorney for NRIs buying a flat.

Step 3: Payment Plan and Home Loan

Ask which payment plan is available on the day you book. A 20:80 payment plan has been reported for this project; confirm the current plan in writing before you rely on it. Read the 20:80 payment plan explained to understand how such plans work.

If you are taking a home loan, get an in-principle approval early, and check that your lender has approved the project. Our home loan guide for premium flats in Mumbai and home loan tax benefits explain the details.

Step 4: Allotment Letter and Agreement for Sale

After your booking is accepted, the developer issues an allotment letter that confirms your unit and the main terms. The next step is the agreement for sale – the main contract between you and the developer.

RERA rule: under Section 13 of RERA, a developer cannot accept more than 10% of the cost of the apartment as an advance or application fee without first entering into a written agreement for sale and registering it.

Read the draft agreement carefully, ideally with a lawyer. Check the carpet area, price, payment schedule, possession date, parking and penalty clauses. Our guide to key clauses in an agreement for sale tells you what to look for.

Step 5: Stamp Duty and Registration

The agreement for sale is registered at the sub-registrar office after stamp duty and registration fees are paid. Both buyer and developer (or their authorised representatives) sign before the sub-registrar. Keep the registered copy safely – you will need it for your home loan and for possession.
