External Features of the Building

This section provides the external features of the building selected. The external features consist of materials, bricks, blocks, and concrete used to build the house described in this report. In addition, the external features of the building also consist of a cavity wall, roof structure, and ground floor. (Ely, The Plan Collection, (2008). The building materials used for external features are a combination of the modern method of construction (MMC) and the traditional method. An MMC is a type of construction method that makes use of timber panels for construction. Typically, the MMC is the latest method of construction adopted because it is easy to construct. The home building chosen for this report has also adopted traditional methods of construction such as bricks, blocks, and concrete. (Parliamentary Science and Technology, 2003, Forticrete, (2008).

Walls of the Building

For the wall of the building, the aggregate concrete block is used for the wall. It should be noted that the fixing of the aggregate concrete block for the building embraces the medium fixing that filled the hollow portion of the building. The use of medium fixing of the building has heavy gauge fixing, and in the building, there are some design requirements that were followed. The block strengths are considered in the construction of the building. In addition, the building engineer choose the correct method of fixing the system that was suitable for weather hollow and suit loading. The wall design of the building is not impaired, and there are no holes whatsoever in the building. (Bassetlaw).

Meanwhile, each block used for constructing the building has a fixing of 35mm from the end of each block. (See the wall of the building in Figure 5)

Structural Stability

The external walls of the building is being supported by the partitions of the internal frames which includes flank walls, roof timber, and floor joists. The structural viability of the building complies with the BS 5628, Part 1: 1992 of code of practice of structural building.

Materials for the Window

The building also adopted window frames and timber frames for construction. The Timber frame and timber panels are the materials used for the construction of the windows of the building. (The Info Shop, 2008). Typically, these materials have provided sound insulation with a high-level standard. Moreover, this house contains thermal insulation that is used to ensure that there is absolute minimization of heat loss.

Insulation of the Building

The system of insulation employed for the building is with the regulation of EnEV 2004 requirements. Typically the annual heating demand is approximately < 15 kWh/m²a, and since the building was built in 2005, the building adopted the regulation of insulation system of 2004 with 30% energy-efficient system.

Roof

Moreover, the roof of the building consists of light red colour that has a specification size of 38mm x 25mm as well as has a span of 600mm. In addition, the fixing was made by an aluminium nail with the specification of 50mm x 3.35mm, which is in line with BS 5534:2003.

The roofing for the building has a strong overlock and underlock that is effective for rain drainage. Moreover, the roofing also has interlocking features that have the performance of blocking the ice and providing better rain drainage. All the roofing of the building is in line with BS 5534:2003. Thus, the setting of the roof is incorrect procedure there is adequate strength used in footholds to ensure adequate protection of the slates. (Forticrete, 2008). In addition, part of the materials contains light red roofing that is appropriate to ensure that there is a minimization of environmental impact.

Fire Protection

The external wall of the building complies with the Approved document B that describes the system of fire resistance for the building. Typically, the fire resistance procedure of the building is in line with fire resistance of 30mins to 120mins. The bricks used for the building have the component of resisting fire with the optimum standard. The external wall of the building consists of brickworks that can reduce the spread of fire in case of fire occurrence.

Damp Proof Course for the Building

The external wall of the building is built to protect the building from moisture. Thus, the external wall is in line with Damped Proof Course to protect the external wall of the building against moisture. Typically, the materials used for the protection against moisture are bricks that are in line with BS 743 and BS 8215 specifications. Typically, the design and installation are in line with the code of practice of DPC masonry construction.

Opening

Head

The head is in form of beams that were made from the MMC materials. The MMC materials are made up of a Timber frame.

Jamb

The Jambs is referred to the vertical part of the building, which shows the opening on the cavity of the wall. Thus, to prevent moisture from entering the cavity it is essential to seal the cavity. Thus, fig 1 shows the wall jamb of the building.

Fig 1: Wall jamb of the building.

Internal Features of the Building

This section consists of the internal part of the building. The internal part of the building consists of the floor plan and electrical installation in the building.

Typically, the floor plan of the building gives the dimension that specifies the length of the wall, and the sizes of the room. Essentially, these floor plans contribute to the electrical fitting system in the house.

Floor Plan

The floor plan reveals the ground floor of the building, and on the ground floor, there is a principal room that is 10.34m long. The shape and dimensions of the room are 6.83m x 3.45m and 5.64m x 3.33m. In addition, the room has cupboards that are double-shelved.

The internal features of the building also consist of Kitchenette, with a dimension of 2.08m x 1.68m. The kitchen also has a fitted floor cupboard that has a radiator, wall cupboard, and other spaces. (Aggregate Industries, 2009).

The dimension of the first floor of the building is 6.1m x 3.35m that including the staircase. The dimension of the room is also 6.1m x 3.35m with radiator and strip lights. (See Figure 6 for the floor plan of the building).
