The Scot arrived at Villa Park last summer charged with overhauling the team and implementing a long-term strategy to build for the future.
That meant buying bargains from the lower leagues and developing homegrown talent and did lead to his inexperienced side struggling for much of the campaign.
However, the mood around the club is extremely upbeat with most of the squad boosting their reputations despite their battle against the drop.
Lambert has promised improved deals for a number of his emerging stars - but sees no reason why he himself should be rewarded with an extended or improved contract by owner Randy Lerner.
"It's not a small project," he said.
"It's not a conversation I have had with Randy. I have great respect for him.
"I signed three years here, so I've got two more to go. But it's not about me. This football club is more important than anyone. My job is to keep building it.
"It's been a really hard year. We deserve incredible credit for what we have done. This football club has a magnificent history but you have to keep evolving as time goes on."
Reflecting on this season, Lambert said: "I am delighted for the lads and supporters. I am thrilled for them. They have seen what we have been doing here.
"You wouldn't get 42,000 in the stadium if they weren't behind it. The big test is whether the supporters stay with it. They have been absolutely brilliant.
"They are a young team but they are getting better and better. Sir Alex Ferguson said it himself: 'If you have young players and they stick with you for a few years naturally you're going to get a really good side'. You just have to add to it."
When Villa were at their lowest ebb around Christmas time Lambert was urged to seek funds to bring in experienced - and perhaps overpriced - reinforcements.
However, he never lost faith in his young side and chose instead to back the men he had while adding two more unproven faces in Yacouba Sylla and Simon Dawkins.
"I don't think I had to prove anything to anyone," said the former Norwich boss, whose side face relegated Wigan at the DW Stadium on Sunday.
"My main focus was always on the players and getting results. What was going to happen to me was going to happen. I never lost any sleep over it.
"I know football and what it's like. In football you can be sacked and it doesn't have to be results-based any more. You have that now with managers leaving clubs. You get sacked or leave clubs for nothing now. So what was going to happen was going to happen."
