Who is this twin duplex plan for?
Twin Graduer is two duplex homes-built side by side on one plot. This plan suits an owner who wants two units in one build. You can live in one unit and rent out the other, or house two families, such as parents and a married child or two brothers. Each household gets its own two-storey home, so everyone has privacy while you build only once.
The 14 m x 13 m footprint fits a 100 ft x 100 ft plot, so it is a good match if you own a large or double-size residential plot. Before building, confirm the setback and approval rules of your state or local planning authority.
Room-by-Room Layout
This twin duplex has two identical units, built as mirror images of each other. Each unit has the layout below.
Ground Floor

- Ante-room with W/: Just inside the door is an ante-room with a toilet. Visitors can use it without going further into the house.
- Sitting room: The sitting room is the main living space, close to the entrance. It is where you receive guests.
- Dining area:The dining area sits next to the sitting room and the kitchen, so serving meals is easy.
- Kitchen with balcony and pantry: The kitchen has a pantry for food and supplies. It also has a balcony.
- Staircase: The staircase connects the ground floor to the first floor.
- 1 Bedroom (en-suite): The ground floor bedroom has its own bathroom. It works well for a guest, a relative or anyone who prefers not to use the stairs.
First Floor
- Mini lounge with balcony: At the top of the stairs is a mini lounge with a balcony. The family can relax here without going downstairs.
- Master bedroom (en-suite) with walk-in closet: The master bedroom has its own bathroom and a walk-in closet.
- Terrace: The first floor has a terrace for open-air space upstairs.
- 1 Bedroom (en-suite) with walk-in closet. The second upstairs bedroom has its own bathroom and a walk-in closet.

How Much Does It Cost to Build a Modern Twin Duplex
The cost of building the Twin Grandeur depends on your location, the quality of finishes, the price of materials at the time you build, and whether you use a contractor or manage the project yourself.
A twin duplex has two storeys and two homes under one roof. That means more foundation, columns, beams and slabs than a bungalow. It also has two kitchens, two staircases and a bathroom for every bedroom. These are the areas where costs add up. Parking, terraces and balconies, as in this design, also add to the cost.
This is why every Twin Grandeur plan comes with a free bill of quantity. It lists the blocks, cement, roofing, finishes and labor you need, so you can price each item at current market rates in your area instead of guessing. Material prices in Nigeria change often, so check them again before you buy.
