FOUR BEDROOM BUNGALOW DESIGN AND FINISHES

Overview of the Bungalow Design

The four-bedroom bungalow is a contemporary coastal residential structure designed to blend elegance, comfort, and functional space utilization. From the 3D renderings, the building features steep gabled roofing with asphalt shingles, a well-raised entrance porch supported by classical columns, and a multi-tone exterior palette that blends white walls with subtle orange and green accent lines. The layout consists of a spacious living room, a dining area, a kitchen, four bedrooms (including a master suite), and additional utility spaces. Designed with a panoramic ocean view in mind, the layout takes full advantage of natural lighting and cross ventilation.

Land Size and Orientation

The property is ideally suited for a 100 ft × 100 ft land parcel (approximately 929 square meters). The building footprint takes up roughly 55% of the land, leaving ample space for parking, gardening, and walkways. The front setback is designed with tiled concrete paving blocks, and side walkways are spaced to allow for future extensions or landscaping. The building is oriented to maximize sea views and passive cooling, with wide windows and multiple access doors from the sides and the front porch.

General Room Layout and Functions

The floor plan is segmented into three major functional zones: the public zone (living and dining), the semi-private zone (kitchen and service areas), and the private zone (bedrooms). The front porch leads to a well-ventilated living room with clear access to the dining and kitchen areas. Each bedroom is en-suite, with a central corridor providing access. The master bedroom features a walk-in closet and private balcony. The kitchen comes with modern cabinetry spaces, island counter options, and proximity to the dining for efficient meal service.

Roof Design and Materials

The roof is a multi-gabled design using high-quality asphalt shingles. The pitch and angle of the roof help with water runoff and heat deflection, critical for the coastal environment. Beneath the shingles, a waterproof underlay is installed over treated wooden rafters. Fascia boards and soffit panels are painted in weather-resistant finishes. Ridge vents and eave ventilations have been incorporated for thermal comfort inside the attic area.

Columns and Exterior Structure

Two prominent columns at the main entrance porch enhance the structural and aesthetic appeal. These columns are 300mm × 300mm reinforced concrete, finished with decorative plaster and painted in white. The bases are enlarged to support the raised platform and staircases leading to the front door. Balustrades are installed using black-coated metal for durability and aesthetics. The side verandas also feature balustrades and double-leaf entrance doors for accessibility.

Window and Door Specifications

The design utilizes aluminum-sliding windows with integrated mosquito nets. Each standard bedroom window is sized at 1500mm × 1200mm, and living area windows are as large as 1800mm × 1500mm. The main doors are solid-core hardwood with frosted glass panels for security and light entry. Internal doors are flush panel wooden designs, with modern locks and stainless steel handles.

Interior Finishes – Living and Dining Areas

The living room and dining area floors are finished with 600mm × 600mm vitrified tiles. The walls are treated with putty, smoothened, and painted in neutral cream. Ceiling boards are made of POP (Plaster of Paris), with decorative lighting recesses and chandelier provisions. The furniture placement reflects a modern open-plan layout with visual connection to the kitchen and outdoor views.

Kitchen Layout and Features

The kitchen is designed with ergonomics in mind, featuring L-shaped cabinetry along the walls, overhead storage units, and space for modern appliances such as refrigerator, microwave, and dishwasher. A central island counter provides extra workspace and doubles as a breakfast table. The backsplash is done with ceramic tiles, while granite countertops offer durability and style. Plumbing lines are installed for both hot and cold water.

Bedroom Layout and Finishing

Each of the four bedrooms is spacious enough for a queen-size bed, side tables, and wardrobes. The master bedroom is approximately 5m × 5.5m in dimension and includes a walk-in closet area and private bathroom. Flooring is polished ceramic tiles, while the walls are painted in pastel tones for a restful atmosphere. Electrical points include sockets for bedside lamps, TVs, and air conditioning.

Toilets and Bathrooms

Each toilet is fitted with water closets, shower cubicles, wall-hung vanities, and ceramic floor tiles with anti-slip texture. Bathroom walls are tiled to full height (2.4m) using 300mm × 600mm tiles. Plumbing fixtures are stainless steel, including mixers and shower heads. The master bathroom also includes a bathtub and his-and-hers sinks.

Electrical Installations and Fittings

The electrical system is designed for optimal safety, energy efficiency, and modern convenience. The building is wired with 4mm and 2.5mm PVC-insulated copper wires for sockets and lighting, respectively. Each room is fitted with double wall sockets, ceiling LED light points, and provisions for air conditioning units. The distribution board (DB) is mounted in the corridor and connected to a 100A main breaker, split into separate circuits for lighting, sockets, and high-power appliances. Circuit breakers include 10A, 16A, and 32A for specific loads. Lighting includes recessed LED spotlights in the ceilings and pendant fixtures for the dining and living rooms. A conduit wiring system was used for aesthetic concealment. All wiring is done according to Nigeria’s Electrical Installation Standard Code.

Plumbing and Sanitary Works

The plumbing system comprises both water supply and drainage. PPR (Polypropylene Random Copolymer) pipes are used for hot and cold water lines due to their high resistance to pressure and temperature. 1-inch main water lines connect to ½-inch branch lines with gate valves for each room. A 2000-liter overhead tank provides water storage, with a pressure-boosting pump to ensure adequate flow. All toilets are connected to a manhole network leading to a standard septic tank with soak-away pit. Fixtures include wall-hung water closets, ceramic hand basins, floor drains, and PVC vent pipes. Kitchen sinks are stainless steel double bowls with strainer waste systems.

Paint Finishing and Wall Treatments

Exterior walls are painted with weather-resistant acrylic paint, selected for durability against coastal humidity and salt exposure. The primary color is off-white with mustard yellow trims. Internal walls are finished in satin emulsion paint in warm beige, cream, and soft green shades for different rooms. A two-coat system (primer + two top coats) is used for both interior and exterior surfaces. Skim coat plastering was done to enhance smoothness. POP ceiling cornices are painted in white with detailed edging.

Ceiling Details

The entire house uses POP ceilings with intricate recessed designs in the living room and master bedroom. Other rooms are plain white with central lamp holders. The ceiling height is approximately 3.3 meters from finished floor level, enhancing ventilation and light reflection. Light troughs and LED strip holders are pre-installed in decorative bulkheads. Ceiling battens are made of treated hardwood with anti-termite coatings.

Security Features

The bungalow includes anti-burglary metal reinforcements in all windows and main doors. The front and rear entrances are double-locked with mortise and deadbolt systems. Window glass is laminated for impact resistance. Provision for a video door phone and CCTV points are made, with underground conduit pipes from gate to main house for future security installations.

Ventilation and Natural Lighting

The building design prioritizes cross-ventilation, especially critical in coastal areas. Each room has at least two windows placed in opposite directions to facilitate airflow. Large sliding windows and louver openings above doors improve thermal comfort. The roof design also includes vent blocks and air vents for attic heat release.

Water Supply and Drainage

The house features a borehole system feeding into the 2000L elevated water tank. PVC 4-inch drainage pipes connect all waste outlets to the septic system. Kitchen and bathroom water is channeled through grease traps before entering soakaway. Roof rainwater is collected through PVC gutters and directed to underground drains around the site perimeter.

Perimeter Fencing and Gate Design

A 2.5-meter-high concrete block fence surrounds the property, finished in plaster and paint matching the main house. The front gate is a 3.5m-wide sliding steel gate, powder-coated in black. A pedestrian gate is integrated, and a small gatehouse is included at the entrance for security personnel.

Site Layout Plan

The building is positioned with a front setback of 8m, side setbacks of 3m on both ends, and a rear buffer of 4m. This layout provides for vehicular maneuvering, green areas, and future expansion. Concrete paving stones are used for the driveway and walkways, bordered with black-and-white kerbs for visibility.
