The building height from the ground to under the eaves is 2.7m whereas according to AS4055_2012 section 1.2 for wind classification to be determined the distance from the ground t the underside of the eaves shall not exceed 6.0m. Also, AS1684.2_2010 section 1.4.2; states hat the maximum building height shall not exceed 8.5m. the two conditions have been satisfied hence the wind classification of the drawings provided by Mr and Mrs Walk can be done according to the two codes.
ii. Plan shape
Wind classification can be determined and the plan shape of the building sized according to AS4055 and AS1684.2. The shape of the house provided in the plan. AS4055_2012 section 1.4.6 and AS1684.2_2010 section 1.4.3 provides that the building shapes shall be essentially rectangular, square, L-shaped or a combination of rectangular...

Hence, the building qualifies. iii. Number of storeys of timber framing
Wind classification can be determined and the number of storeys of timber framing of the building sized according to AS4055 and AS1684.2. AS1684.2 section 1.4.4 provides that the number of storeys shall not exceed 2. The plans of the building provided by Mr and Mrs B Walk is a single storey hence within the scope of the codes.
iv. Width
Wind classification can be determined and the width of the building sized according to AS4055 and AS1684.2. The width of the building in the plan provided is 10540mm wide. According to AS1684.2_2010 section 1.4.5, the maximum width of the building shall be 16000mm, excluding eaves. Therefore, the width is within the acceptable width limits for analysis according to the codes.
v. Wall height
Wind classification can be determined and the wall height of the building sized according to AS4055 and AS1684.2. According to AS1684.2_2010 section 1.4.6, the maximum height shall be 3000mm. from the building elevations by Mr and Mrs B Walk, the maximum height is 2700mm which is within the limits provided hence the building…
