⚡ Quick Answer
To read a floor plan well, start with the carpet area, then check room sizes, the direction of key rooms, windows and ventilation, how the rooms connect, and whether your furniture fits. In a 4.5 BHK, look closely at how the extra room is planned.
- At L&T The Gateway Sewri, the 4 BHK has a carpet area of 1,905 sq.ft and the 4.5 BHK 2,238 sq.ft.
- That is a difference of 333 sq.ft of carpet area.
- 3 BHK floor plans and carpet area are shared on request.
A floor plan is the closest thing you have to walking through a home before it is built. For a large purchase like a 4 BHK or 4.5 BHK, learning to read it properly can save you from surprises later – a bedroom that cannot fit a wardrobe, a living room with little light, or an extra room that turns out smaller than you imagined.
This guide explains how to read a floor plan step by step, what to look for in larger homes, and how the 4 BHK and 4.5 BHK homes at L&T The Gateway Sewri compare on carpet area.
Understanding the Basics of a Floor Plan
A floor plan is a drawing of the home seen from above. Most plans use a few standard elements:
- Walls: thick lines show external and load-bearing walls; thinner lines show internal walls.
- Doors: shown as a gap with a curved line that shows which way the door opens.
- Windows: shown as thin double or triple lines within the wall.
- Room sizes: usually written inside each room, in feet and inches or in metres (for example 12’0″ x 14’0″).
- North arrow: tells you which way the home faces.
If anything on the plan is unclear, ask the sales team to explain it. A good team will happily walk you through it.
Start With Carpet Area
Under RERA, developers must state the carpet area – the usable floor area inside the walls of the home. It is the most reliable number for comparing homes. Built-up and super built-up areas include walls and shared spaces, so they always look larger.
Here are the carpet areas shared for L&T The Gateway Sewri:
| Configuration | Carpet area | Price |
|---|---|---|
| 3 BHK | On request | On request |
| 4 BHK | 1,905 sq.ft (176.98 sq.m) | On request |
| 4.5 BHK | 2,238 sq.ft (207.92 sq.m) | On request |

Check Every Room Size
Room dimensions tell you far more than the total area. For each room, ask yourself:
- Can the master bedroom fit a king-size bed, side tables and a wardrobe, with space to walk around?
- Are the other bedrooms large enough for a bed, wardrobe and study table?
- Is the living and dining area wide enough for the sofa and dining table you plan to buy?
- Is the kitchen practical, with enough counter and storage space?
A simple trick: measure the furniture you already own and sketch it onto a printed copy of the plan.
Look at Light, Ventilation and Direction
Use the north arrow to see which way the main rooms face. Many buyers in Mumbai prefer living rooms and balconies that catch the breeze and good natural light. Count the windows in each room and check that bathrooms and the kitchen have proper ventilation.
In a high-rise near the sea, views also matter. At L&T The Gateway Sewri, many homes are planned with views of the Arabian Sea and the harbour, but the view depends on the tower, floor and direction – so ask to see it for the exact unit.
Study the Layout and Flow
A good layout separates private and shared spaces. Look at how you move through the home:
- Can guests reach the living room without passing the bedrooms?
- Is the kitchen close to the dining area?
- Are bedrooms placed for privacy, with attached bathrooms where you need them?
- Is there a separate entry or space for household help, if you need one?
- Is there enough storage, utility space and room for a washing machine?
What to Check in a 4.5 BHK
The “half” in a 4.5 BHK is an extra room that is usually smaller than a full bedroom. It may be planned as a study, home office, staff room or flexible room. On the floor plan, check:
- SizeIs it big enough for the use you have in mind, such as a desk or a single bed?
- WindowDoes it have a window for light and fresh air?
- AccessDoes it open from the living area, a passage or the kitchen?
- BathroomIs there a bathroom nearby, especially if it is a staff room?

Why should I compare carpet area and not super built-up area?
Carpet area is the usable space inside your home, and RERA requires developers to state it. Super built-up area adds walls and shared spaces, so it is not a fair way to compare homes.
Is the floor plan in the brochure final?
Brochure plans can be indicative. Ask for the approved plan of your exact unit and check that it matches the plan attached to your agreement.
Can I change the layout of my flat?
This depends on the developer and the structure. Ask the sales team in writing before booking if you plan any changes.
