Answer:
From, left to right:
#1 Mrs Scott - glass
#2 Mrs Umbrella - straw
#3 Mr Tinsley - brick
#4 Mr Wilshaw - wood
If we separate and label the clues, and label the bungalows #1, #2, #3, #4 from left to right we can see that:
a. Mrs Scott's bungalow is somewhere to the left of the wooden one.
b. The third one along is brick.
c. Mrs Umbrella owns a straw bungalow
d. Mr Tinsley does not live at either end.
e. Mr Tinsley lives somewhere to the right of the glass bungalow.
f. Mr Wilshaw lives in the fourth bungalow
g. The first bungalow is not made from straw.
By (g) #1 isn't made from straw, and by (b) nor is #3. By (f) Mr Wilshaw lives in #4 therefore by (c) #2 must be straw, and Mrs Umbrella lives there.
Therefore by (d) Mr Tinsley must live in #3, which, by (b) is the brick bungalow.
By (a) #4 must be wooden (otherwise Mrs Scott couldn't be to its left) and by (f) Mr Wilshaw lives there.
Which leaves Mrs Scott, living in #1, the glass bungalow. QED.
There are four bungalows in our cul-de-sac. They are made from these materials: straw, wood, brick and glass.
