The most frequent complaints were rain water entered house through window. There are two main reasons to the problem. Firstly, the faulty detailing where a concrete copping is placed at the bottom of the window opening (see Figure 16). When rain water hits the concrete copping at the bottom of the window, rain water then bounces into the interior space of the unit through gaps between the glass panes. Secondly, the quality of workmanship where gaps between wall openings and window frames is not water tight, water seepage occurred at gaps between window and wall. Water proofing problem especially at toilet and bath is very crucial. Good site supervision and workmanship is critically important to resolve the problem. Otherwise, it is very costly and troublesome if to carry out any remedial work after completion.With the overall unit size of 650 square feet, in order to provide bigger kitchen, yard and bathroom, other rooms might need to be reduced in size. Table 8 shows the size comparison for room function between the By-law 42 & 43 of Uniform Building By-Law (UBBL), CIS 2 and existing design (PPR 2000). It is important to highlight that even the existing design (PPR 2000) is not meeting the minimum unit size stated in the CIS 2. Although Bedroom 3 received the lowest degree of satisfaction compared with bedroom 1 and bedroom 2 because of the existing odd corner, generally respondents are quite satisfied with the sizes of existing bedroom 1, bedroom 2 and bedroom 3. The size of existing kitchen is smaller than minimum as stated in CIS 2 but still complying with the minimum size as stated in UBBL. So, the question is should the revised design to comply with CIS 2 standard or is that any alternative size which is more appropriate.From the questionnaire survey, an alternative layout with kitchen size of 6.56 square meters (71 square feet) was proposed. The alternative kitchen size has received high degree of satisfaction compared with the existing kitchen size (see Figure 6). The space requirement for residential layout guideline, 1984 from Gravesham Borough Council, United Kingdom recommended that the minimum size for kitchen is 7.20 square meter or 77 square feet. Therefore, the minimum size for kitchen for the revised design should be aimed at 7.20 square meters (77 square feet). The space requirement for residential layout guideline, 1984 from Gravesham Borough Council, United Kingdom also recommended that if bathroom and water closet are to locate in the same room, the minimum size should be 3.50 square meters (38square feet). This size is much bigger than size as stated in CIS 2 as well as the existing bathroom size. As such, the minimum bathroom size for revised design if it is complete with water closet should be aimed at 3.50 square meters. Table 9 shows the selected rooms‟ function sizes of floor space requirements for residential layout guideline recommended by Gravesham Borough Council.
