Duplex House Design in Bangladesh Features:

1. Grand Entry:

Generally, we provide a grand entry in a duplex house. This entry is considered the main entrance of the house. The main theme of these entries is mainly architectural beauty. It also represents the primary taste of the inner house. We must make it very spacious and restricted to public access. Generally, we try to connect the grand entry with a boundary wall on both sides. This may connect with an approach road or a highway.

2. Landscaping:

Most importantly, we try to create landscaping in front of the building and surroundings.  We keep vehicles and pedestal movements separately. Especially, we provide a fountain in front of the house. Also, an open yard seating area, swimming pool, fishpond, tree plantations, vegetable cultivating area, flower garden, etc. A Landscape design enhances the ultimate luxury of a duplex house.

3. Guest Zone:

We always try to create different zones according to their usage. We always keep the guest zone on the ground floor. Guest zone comprises with formal living area, common toilet, and other common facilities. Generally, we keep this area very near to the house entrance. We keep the guest gathering and their movement restricted to this area. Strictly, we maintain the privacy of family members. It is our important design consideration.

4. Service Zone:

We design a Duplex House according to the zoning concept. We create a service zone as a semi-private zone of the entire building. It is also located on the ground floor. We provide a large dining hall and kitchen are the main parts of the service zone. Generally, we consider the movement of the female members in the service zone very private. The interactions of guests in the service zone are considered a critical part. Additionally, we try to place the servant bedroom and toilet very near the service zone.

5. Family Living Area:

We consider this a very private and restricted to guests. Generally, we try to locate it on the 1st floor. The family living area comprises master beds, common beds, child beds, a reading room, and a prayer room. This place is kept very secure from the ground floor. Sometimes we provide a small drawing and pantry in a suitable location. We believe that it enhances the in-house refreshment facilities. We consider this zone as the main living area of duplex dwellers.

6. Large Family Terrace:

Most Importantly, a large family terrace is desirable in any modern duplex house. Generally, we place the family terrace very near the family living area. We always try to place it on the 1st floor. Also, we try to keep this terrace as common to use for all family members. We consider this place as the main refreshment place for building dwellers. Especially, we keep terrace gardening and planter boxes to enhance the beauty of a family terrace.

7. Vertical Fins and Pergolas:

Generally, we consider the vertical fins and pergolas as the ornamental components of a duplex house. We provide those to add some extra look to exterior views. It’s generally located at the front and side elevations of duplex houses. The height of the vertical fins is more than the duplex house. It starts from the existing ground level and extends beyond the roof. The pergolas are placed over the open terrace and rooftop. We try to make fair-faced casting and rustic tiles to give them a different look.

8. Elegant Internal Stair:

We always connect two floors of a duplex house with an elegant internal stair. Most importantly it connects the drawing room to the private living zone. We try to build such stairs with elegant architectural views. It may be spiral, circular, elliptic, parabolic, or oval shape. You can make it with RCC or prefabricated steel. The rise and trade of such stairs may be made with Wood or tempered glass.

9. Rooftop Swimming Pool:

Modern duplex or triplex villas always demand a rooftop swimming pool. Generally, we design a swimming pool in an amoeboid shape. Other shapes also can be made as per the client’s needs. The swimming pool comprises a changing room very near to it. We try to place a sitting area on the bank of the pool. Sometimes we keep a small toilet near the swimming pool. Generally, the pool is open to the sky. Also, maybe a transparent sheet over it to protect the Sun.

10. Water Fountains:

Water fountains add extra luxury to the duplex house. Generally, we design two types of Water Fountains depending on their locations. Firstly, Indoor water fountain. Secondly, the outdoor water fountain. We place indoor water fountains near internal stairs, dining room, or living room. The outdoor water fountain is placed in front of the building. It can be wall-mounted or vertical sprinkler type. Wish to hear a waterfall sound while sitting at your home? You can install it at any suitable place.

11. Fish Ponds:

The fishpond is an ornamental part of a duplex house. Generally, we place these types of ponds outside of the house. Especially at the main entry gate. Different colorful foreign fishes are grown here naturally. Water circulation is run with the help of a special water pump. However, the maintenance cost of such a pond is high and tiresome. It is becoming very popular among duplex house owners due to its mind-blowing features.

12. Rooftop Gym:

The rooftop gym is an extra facility for the luxurious duplex villa. Family members can perform their morning and evening workout at their gym. We make a space for a treadmill, lifting weights, and dumbbells, and cycling on it. It is always very difficult to go for a workout in the morning or late at night. The demand for small workouts can be mitigated with this type of Gym. We place a small toilet and prayer room near the gym.

13. Common Facilities:

A duplex villa house required some service people and common facilities. We place those common facilities on the ground floor. Car parking, guard post, guard living room, caretaker room, kitchen and toilet, drivers waiting, etc. These common facilities increase the living comfort of duplex dwellers. We arrange a suitable place for a substation and generator for 24-hour power supply.
