Where can symbolism be found in A House for Mr. Biswas?

One of Mohun Biswas's most cherished dreams is to build a house of his own. Mr. Biswas was raised in a simple mud hut and has since led an itinerant lifestyle, moving around from place to place without ever feeling truly settled. It's not surprising, then, that a home of his own is a very important goal in his life.
Mr. Biswas makes a number of attempts to build his own house, but all end in failure due to extreme weather conditions and fire. It seems as if he will never make his dream come true. But one day, almost on the spur of the moment, he buys a dilapidated old house from a solicitor's clerk. It's not much, but it's a place he can finally call home.
I'd like to suggest that Mr. Biswas's quest for a place of his own is symbolic of his native Trinidad's struggle for independence. As with all anti-colonial struggles, Mr. Biswas encounters a number of setbacks in his attempts to lead an independent life. And even when he finally does obtain a place of his own, it's quite a rickety old structure, requiring a lot of hard work to make it tolerably habitable. So it was with the independence of Trinidad, or indeed any former colony. Once freedom had finally been achieved, then the hard work really started.
