This 18×55 feet 3BHK house plan is crafted for elongated plots where depth allows better spatial layering and comfort. With an 18-foot frontage and extended 55-foot length, the design creates a gradual transition from public areas at the front to private zones toward the rear.

The entrance staircase, approximately 6 feet wide, is positioned at the front for convenient upper-floor access. Adjacent to it, two common toilets are arranged centrally, ensuring accessibility from all bedrooms without disturbing the living areas.

The drawing room spans around 13 feet in depth and flows naturally into a 15.5-foot dining area, forming a generous central living corridor. This extended layout provides flexibility for furniture arrangement and family gatherings.

Three bedrooms are proportioned between 10 to 12 feet, offering balanced sleeping spaces along the length of the house. The kitchen, measuring approximately 5.5×9 feet, is located at the rear corner for efficient utility separation and ventilation control.

Overall, this 18×55 configuration demonstrates effective zoning across a deep residential plot. It supports future expansion, maintains practical circulation, and offers comfortable proportions suitable for medium to large families seeking a well-organized three-bedroom layout.
