I dont have any seating plans for the house of commons, but I am familiar with the parliamentary tradition under which the seats are distributed. I will explain it: 

 begin on the government benches. begin at the speaker. fill up as many goverment seats as possible. Under a majority, you will reach the end. If this happens, next, you move to the opposition benches. The government again starts at the speaker, and goes down the benches as far as it will stretch. Next is the official opposition, followed by other opposition parties. Independents can be shuffled around to make seating simple, but in general, they go in the last seats. In the event the opposition has so few seats, that the leader of the opposition could not sit across from the prime minister, then the government can hold seats on the opposition benches both nearest to the speaker, and farther from the speaker, such as exists currently in the canadian senate. Though this should not be an issue except possibly in 1984 and 1957. 

 hope this helps.
