Puerto de la Duquesa · New build & off-plan
At Duquesa, off-plan usually means a licensed reform
Nothing further can be built on the Duquesa quays, and the ground beside the port is a listed Roman site, so a home sold here as new is almost always a licensed reform of a first-generation quayside block. That changes which protections you actually have, and Ley 20/2015 is not one of them.

Begin with the ground, because at this address it is not ordinary development land. The Castillo de la Duquesa beside the port carries Bien de Interés Cultural status under reference RI-51-0008052, protected by the generic declaration of the decree of 22 April 1949 and by Ley 16/1985 on Spanish historic heritage, and the surroundings of that fort are themselves a designated Roman archaeological site holding a villa, baths, a necropolis and a fish-salting factory. Whatever a brochure implies about building beside the port, ground works there sit inside a heritage regime that answers to the Junta's cultural administration as well as to the town hall. That is a rare constraint on this coast and it deserves to be understood before a reservation, not after.
The consequence is that the interesting question here is not which promoter to choose but whether you are dealing with a promoter at all. A licensed reform of a quayside flat is bought from an owner, and money handed to an owner mid-project has none of the statutory cover that money handed to a developer does. There is also a practical dimension particular to this basin: materials arrive along a working quay past restaurant terraces, and the Ayuntamiento de Manilva licenses the work while your comunidad de propietarios controls anything that changes the water-facing façade. Two consents, one narrow access route, and a summer in which very little can be delivered.
What is under construction here, and what is not
The verifiable position, as at 26 August 2026, is a negative one and it is more useful than a brochure. The quayside ring around the basin was completed long ago and its 328 berths are a fixed quantity; the land immediately beside the port is occupied by a listed eighteenth-century fort and a protected Roman site. Neither of those is a redevelopment opportunity waiting for a promoter. Genuinely new construction in this municipality happens inland, on the Manilva hillside, where residential building has been the leading economic sector for decades.
So an off-plan search that starts at Puerto de la Duquesa usually ends in one of two places. Either you buy a reform on the water and accept that your protection is contractual rather than statutory, or you buy something genuinely new behind the port and accept that you have bought a hillside address rather than a quayside one. Both are legitimate. What is not legitimate is a brochure that blurs them, and the way to test it takes one question: the licence number, and the name of the promoter it was issued to.

How this runs, step by step
-
Step 1
Establish what is genuinely new
Specific to Manilva
Ask three questions before anything else: who is the registered promoter, what is the licence number, and on which plot. If there is no promoter and no licence number, you are looking at a reform of an existing flat, however the marketing is worded. That is not a reason to walk away, but it is a completely different transaction and it should be priced and papered as one from the first meeting.

Step 2
Check the ground before the plan
Specific to Manilva
Anything involving excavation near the fort has to be read against the heritage designation. The Castillo de la Duquesa is listed as RI-51-0008052 and the archaeological zone around it is protected in its own right, which means the cultural administration has a say alongside the municipal one. Ask, in writing, whether the plot in question falls inside the protected surroundings and what that adds to the timetable.

Step 3
Secure the deposit, or accept there is none
Where a genuine promoter is selling before delivery, every amount you pay in advance must be held separately and covered by a bank guarantee or an insurance policy under Ley 20/2015, which added the financial-guarantee route to the older building-law regime. Where you are buying a reform from a private owner, that machinery does not exist. Stage the payments against completed work and hold the balance until the keys.

Step 4
Licence the work at Manilva
Specific to Manilva
The works licence comes from the Ayuntamiento de Manilva at Calle Mar 34, and it is separate from the community's consent. Anything that alters the elevation facing the basin — glazing, awnings, a changed opening — needs the comunidad de propietarios to agree in a minuted decision, because on these blocks the water-facing façade is a common element. Get both consents before the builder is booked, not after.

Step 5
Wait for the LPO on new build
On a genuinely new home the licencia de primera ocupación is the municipality's confirmation that what was built matches what was licensed, and it gates the permanent connection of services. Do not sign at the notary before it exists, whatever assurance is offered about it arriving next month. On a reform the equivalent discipline is the certificate of completion and the updated Catastro entry.

Step 6
Snag it, then diary the guarantees
Walk the finished home with an independent surveyor, list every defect in writing and keep the list dated. A promoter's statutory cover runs on fixed periods for finishes, habitability and structure, and those clocks start at delivery rather than at the day you notice something. On a reform, the cover you have is the contract you signed with the builder — so make it specific, in writing, before work begins.
A genuinely new home from a promoter is taxed differently from a resale — IVA plus AJD rather than ITP, at rates the lawyer confirms in writing before you commit — and it is paid in stages against a guarantee. A reform on the quays is a resale purchase followed by a building budget, so the tax is ITP and the timetable is yours to manage. Because Duquesa sits in the corridor's entry band, the specification and the state of the block move the total far more than the address does. The costs most often forgotten are the guarantee, the second set of professional fees and the first year of a community budget nobody has lived through yet.

Questions about this in Puerto de la Duquesa
-
Is anything being sold off-plan on these quays?
-
Treat any such offer as the exception that has to prove itself. The quayside ring is built out and the ground beside the port is protected, so the ordinary answer here is no. If a brochure says otherwise, ask for the promoter's registered name and the municipal licence number, and have your lawyer confirm both at the Ayuntamiento de Manilva before a euro moves. A scheme that cannot produce those two things is not an off-plan purchase.
↗ -
Does a half-finished reform carry the same protection?
-
No, and this is the most expensive misunderstanding at this address. The guarantee regime under Ley 20/2015 covers sums advanced to a promoter building a home; it says nothing about money paid to a private owner part-way through refurbishing a flat. If you buy a reform in progress, your protection is whatever the contract says and whatever you have withheld. Stage the payments against completed and inspected work, and keep a meaningful balance until handover.
↗ -
What does the Roman site mean for building here?
-
It means the ground next to the port answers to more than the town hall. The fort is listed as RI-51-0008052 and the archaeological zone around it is protected in its own right, so excavation inside that perimeter engages the cultural heritage regime as well as municipal planning. In practice it lengthens timetables and narrows what may be done, which is precisely why the interesting stock at this address is existing buildings rather than new ones.
