Short answer. It depends on the numbers. Under Family Code Article 120, if the improvement cost plus the resulting increase in value exceeds the land's original value, the conjugal partnership takes ownership of the whole lot. If not, you keep the land. Either way, ownership only shifts at liquidation, once the other side is reimbursed.
What the law says
When the cost of the improvement made by the conjugal partnership and any resulting increase in value are more than the value of the property at the time of the improvement, the entire property of one of the spouses shall belong to the conjugal partnership, subject to reimbursement of the value of the property of the owner-spouse at the time of the improvement; otherwise, said property shall be retained in ownership by the owner-spouse, likewise subject to reimbursement of the cost of the improvement.

Two outcomes, one deciding question
The law draws a clean line between two situations. Compare two figures: the cost of the improvement plus any increase in the property's value it produced, versus the property's value at the moment the work was done. If the improvement side of that comparison is larger, the conjugal partnership ends up owning the whole lot. If the property's original value is larger, you keep the land. Either way, money changes hands at liquidation to settle the account.
When the conjugal partnership takes the land
Suppose you owned a parcel worth ₱800,000 before the wedding. During the marriage, conjugal funds built a house on it costing ₱1,200,000, and the combined property is now worth ₱2,500,000 — an increase of ₱1,700,000. The improvement cost (₱1,200,000) plus the value increase (₱1,700,000) easily exceeds the land's original value. In that scenario, the conjugal partnership owns the entire property, but it must reimburse you the ₱800,000 that your land was worth at the time of improvement.
When you keep the land
Suppose instead you owned a large commercial lot worth ₱5,000,000 before the wedding, and conjugal funds built a small storage building for ₱600,000 that added only ₱500,000 to the lot's value. The improvement side totals ₱1,100,000 — far less than the lot's original value. You retain ownership of the land, but the conjugal partnership is entitled to reimbursement of the ₱600,000 it spent building the improvement. The lot remains yours, but the debt to the partnership is real.
Ownership shifts only at liquidation, not mid-marriage
One point that surprises many people: even where the numbers tilt in the conjugal partnership's favour, the ownership of the entire property shall be vested upon the reimbursement, which shall be made at the time of the liquidation of the conjugal partnership. The shift does not happen the day the construction is finished. It happens when the partnership is wound up — on death, annulment, legal separation, or a judicial separation of property — and the financial accounts are actually settled. Until then, the question of who technically owns the lot remains open.
Why this matters if the partnership ends unexpectedly
If the marriage is dissolved before either party imagined, the valuation done at the time of improvement becomes critical. Gather whatever records you have from when the work was done: the deed or tax declaration showing the land's appraised value, construction contracts, receipts, and permits. A disagreement over those figures at liquidation can determine whether a property ends up in the conjugal estate — subject to division — or remains in your exclusive hands, subject only to reimbursement of construction costs.
