His wife Kavitha, a school teacher, supports him unwaveringly, but her patience begins to wane as their dreams of a secure home feel increasingly distant.

As Thamizh begins work on the mansion, he discovers eerie elements hidden in its structure—letters, old photographs, and tools engraved with mysterious symbols.

Guided by the diary, Thamizh faces moral dilemmas, grapples with family conflicts, and unravels the truth behind Rajasekaran's ulterior motives.

In a gripping climax, Thamizh uses his skills, the lessons from Vedhanayagam's diary, and his unwavering resolve to restore the mansion not just structurally but spiritually, ensuring it becomes a symbol of redemption and justice.

The film concludes with Thamizh returning home to his family, now confident that a veedu is not just a physical structure but a place where love, trust, and dreams reside.

Aalukkoru Veedu was written by playwright and screenwriter Sakthi T. K. Krishnasamy, produced by the studio Subhash Movies and directed by Malayalam director M. Krishnan.
