Constructing Environments - Spanman Interim Submission

This section of the site is currently a continuation of the roof as to provide a small sheltered region for the side entrance to the house. Maintaining this connection will create a larger surface area for the roof and provide a flow to point for the region next to it. This slope can also be seen in the top left section of figure 1. located on the left.

STRUCTURAL CONCEPT

The concept of this roof looks at the abstract aspect of design and takes the idea of the ‘triangle’ in order to create a sloped, angular roof structure. Rather than having a large central span and three smaller sections attached to the boundaries where entrances are located, the concept explores the single span idea .

This section is currently a deck leading off from the main house area and has a simple roof providing shelter from the weather. The design takes a similar idea as to the side entrance (explained top right of page), as to extend the main roof section out to these confines in order to created a larger surface area (rainfall, sunlight, etc. explained further on).

This section of the secondary roof structure is more permanent as the other two sections, however, following the same style as the others, continuation of the central span creates a circular pattern of triangles (see figure 1.) and adds to the surface area of the roof space (rainfall, etc. explained further on).

MATERIALS & CONSTRUCTION

Materials:

• Internal• Horizontal Steel Beams - Support framework structure• Angled Connecting Beams - connect to horizontal members and create base plating for glass

and wood frame panelling• Secondary Items

• Bolts - Used to connect members and other components of the internal structure together• Screws - Used to connect members and other components of the internal structure

together

• External• Steel flat roofing panels (see figure 3.) - provide flat roof and allow for rain capture to be

directed to a single point/area.• Glass - Glass sections create skylight and viewing spaces within certain panels and faces of

the roof section• Wood - Used for the framework of the exterior structure - maintains the link to the existing

building.• Paneling for windows/skylights

• Metal Guttering - Sits at the base of the roof and captures water during rain periods - Stored in rainwater tank already existent on site.

• Secondary Items• Bolts - Used to connect members and other components of the external structure together• Screws - Used to connect members and other components of the external structure

together

Figure 3. Steel flat roof paneling

The structure uses a framework system that spans across the wall structure internally. Lateral beams span the central house section, similar to what they do in the existing building (see figure 4.), however these beams will be generated from steel to give additional support and strength to the overall site. From these lateral beams, vertical columns (also steel) are located in regions where the triangles converge (can be seen in figure 5 below). From these nodes, beams run down to the edge sections of the roof and this completes the framework for the roof section of the building.

Wooden and Steel flat roof paneling is used to clad the roof and generate the final product for the design. Sections are also fitted with glass in order to let light into the interior spaces for illumination of the site.

AESTHETIC DESIGN & FUNCTION

As previously mentioned the structure consists of an abstract style, using triangular patterns to form the overall structure. The angle (height) of the triangles are set to provide an enhanced aesthetic appeal, rather than just providing a flat roof. The angle is also shallow enough (but still at an angle) in order for solar panels to be placed on their surface and generate electricity for the site - This also acts to increase the eco-friendliness of the site as a whole. The use of wooden cladding links the new roof design into the pre-existing structure and so the two blend in better together.

The linear nature of the steel flat panels creates a focal point, originating from the vertices and travelling outwards to the edges of the roof structure. The addition of the vertical section (seen in figure 6. and Figure 7 - red circle) also allows for glass to be fitted and a skylight to be generated, allowing light to enter the interior space (both warming and illuminating).

The modern design also helps tie in with the structure due to its modern design as well (not just a conventional tiled roof structure).

Figure 6. Elevations of the roof space

Although the roof is abstract and post-modern, it functions to capture both the use of the sun and the weather in order to become more self-sufficient. This minimises the cost in sustaining the site as well as the environmental impact in which the building is generating to the environment. Although a single roof section, there are two distinct areas in which rain water falls to and so separate water supplies can be set up (one already existing) and these can be used to separate purposes around the site (washing - toilet and gardening, etc.)
