The document describes a design proposal for extensions to an existing bungalow. The ground floor proposal includes extending the bedroom and bathroom and adding a store room and porch. The first floor proposal extends the bedroom and adds a family space and balcony. Reinforced concrete beams and columns support flat concrete roofs over the additions. Load calculations are provided for the dead and live loads of each structural element. Floor plans, structural plans, a 3D model, and load distribution analyses are included.

2.0 INDIVIDUAL PROPOSAL
2.4 Design Proposal ( Surayyn Selvan & Yaseen Syed )
2.4.1 Design Brief
Our extension of the bungalow consists of an extended version of the bedroom and
bathroom located on the ground floor level. An additional store room was added near the linen
room and a porch was added to link the bedroom extension to the outside. Besides that, on the
first floor the bedroom was extended and an additional family space for movies and games was
built adjacent to the study area. A balcony was also built linking the additions together. Flat
reinforced concrete roofs were added to shade everything but the balcony on the first floor. The
materials used for the beams and columns were reinforced concrete and the walls were made out
of brick walls.
Dead Loads of Materials Used (Height X Thickness X Density )
1. Brickwork = 19 kN/m3
3m X 0.15m X 19
= 8.55 kN/m
2. Reinforced Concrete = 24 kN/m3
0.3m X 0.15m X 24
= 1.08 kN/m
Dead Loads (Slab Thickness X Dead Loads)
1. Ground Floor
a) Bedroom ~ 0.15m X 24 = 3.6 kN/m2
b) Toilet ~ 0.1m X 24 = 2.4 kN/m2
c) Store Room ~ 0.15m X 24 = 3.6 kN/m2
d) Porch ~ 0.15m X 24 = 3.6 kN/m2
2. First Floor
a) Family Space ~ 0.15m X 24 = 3.6 kN/m2
b) Bedroom ~ 0.15m X 24 = 3.6 kN/m2
c) Balcony ~ 0.15 X 24 = 3.6 kN/m2
3. Roof ~ 0.15 X 1.0 = 0.15 kN/m2
Live Loads
1. Ground Floor
a) Bedroom = 1.5 kN/m2
b) Toilet = 2.0 kN/m2
c) Store Room = 0.9576 kN/m2
d) Porch = 1.915 kN/m2
2. First Floor
a) Family Space = 1.915 kN/m2
b) Bedroom = 1.5 kN/m2
c) Balcony = 1.915 kN/m2
3. Roof = 0.5 kN/m2
