Short answer. No. Under Article 1803, when management has not been agreed upon, no partner may make any important alteration in the partnership's immovable property without the consent of the others, even if the change would be useful. Only the court can override a refusal that is manifestly prejudicial to the firm.
What the law says
None of the partners may, without the consent of the others, make any important alteration in the immovable property of the partnership, even if it may be useful to the partnership.

Ordinary acts bind the firm, but not this
Where the partners never fixed a manner of management, Article 1803 makes everyone an agent: all the partners shall be considered agents and whatever any one of them may do alone shall bind the partnership. For everyday business, then, one partner acting alone can commit the firm. Important alterations to real property are deliberately carved out of that freedom. Improving, rebuilding, or substantially changing partnership land or buildings is treated as too weighty to be left to a single partner's initiative, because it can lock the firm into large costs and permanently reshape a major asset that belongs to all of them together.
Consent is required even for a useful change
The core rule is strict: none of the partners may, without the consent of the others, make any important alteration in the immovable property of the partnership, even if it may be useful to the partnership. Notice that usefulness is no excuse. A partner cannot justify acting alone by arguing the renovation would benefit the business; the value of the change does not replace the need for agreement. What the article protects is the partners' shared control over their real estate. Each of them is entitled to a say before the firm's land or building is significantly altered, regardless of how good the idea looks to the one proposing it.
When a refusal can be overridden
The law does not let a stubborn partner block a plainly necessary change forever. Article 1803 provides that if the refusal of consent by the other partners is manifestly prejudicial to the interest of the partnership, the court's intervention may be sought. So the remedy for an unreasonable veto is to go to court, not to proceed unilaterally and hope for forgiveness. The threshold is high — the harm from withholding consent must be manifest, not merely inconvenient. Until a court authorizes it, the safe course is to secure the other partners' agreement, because an unauthorized major alteration exposes the acting partner to liability toward the rest of the firm.
