About Vesta Mare
A four-minute walk to the sand. That is Vesta Mare's strongest selling point, and it explains the price straight away. The development is in Castillo de la Duquesa, Manilva's old coastal hamlet around La Duquesa castle, and is one of the few new developments in the municipality that genuinely borders the beach area. In total there will be 145 homes across three buildings, with 1 to 4 bedrooms.
Our overview includes 9 homes, from €435,000 to €1,315,000. The smallest apartment has 1 bedroom, 70 m² and an 11 m² terrace on the third floor, with sea views. Families are more likely to look at the 4-bedroom homes of 161 m²: ground floor for €860,000 or first floor for €900,000. The penthouses are on the fifth floor; the largest has 4 bedrooms, 169 m² and a 59 m² terrace for €1,315,000. Seven of the nine homes have sea views.
What sets this development apart is the history of the land. Roman remains were found during the works. They are being preserved and will have a place in a small interpretation centre, open to residents and visitors. There will also be an infinity pool with sea views, a children's pool, a central square with gardens, an indoor gym and a multi-purpose room for coworking or parties.

Vesta Mare in figures
You pay a clear premium here for a beachside location. The median of €6,344 per m² is 64% above that of new builds in Manilva (€3,880, across 11 developments) and 108% above resale homes in Manilva (€3,043 per m², idealista September 2026). Each extra bedroom costs €142,000 on average: €435,000 for 1 bedroom, €590,000 for 2, €760,000 for 3 and €860,000 for 4. The entry-level apartment comes to around €491,620 all in: €43,500 VAT, €5,220 stamp duty, €2,600 notary and €5,300 lawyer's fees. Do allow for a long wait, though: completion is 29 months away, against a median of 8 months in Manilva.

Location
Castillo de la Duquesa is the historic heart of the Manilva coast. The castle gives the area its own character, with the beach right in front of it. La Duquesa port is close by, with restaurants, shops and an international atmosphere. The municipality lies between Estepona and Sotogrande, with quick connections to both. The development sits at around 10 metres above sea level, close to the shoreline.
In daily life, it is the short distances you notice most. La Duquesa beach is a 4-minute walk, a Dia supermarket 8 minutes and the port also 8 minutes on foot. You reach Estepona hospital in an 11-minute drive. Sotogrande is 16 minutes away, Estepona town centre 17 and Puerto Banús 33. Gibraltar Airport is 38 minutes away, Málaga Airport 73.

Sun, light and views
Here the sun rises at 7:03 on 21 June and sets at 21:42, giving 14.6 hours of daylight. On 21 December you still have 9.7 hours, with the midday sun at 30° above the horizon. Vesta Mare sits at around 10 metres above sea level.
Seven of the nine homes in our overview are listed with sea views. According to the description, many homes look out on the sunrise over the sea; for each home we confirm the view and orientation.
Homes and finishes
Every home gets a home automation system to control the lighting and front door. The kitchens come with appliances, and the homes have heating and energy rating B. Solar panels supply electricity for the communal areas, which can keep service charges down. The living rooms open straight onto the terrace. Because this is a large off-plan development, we check the specifications for each home, the bank guarantees on your stage payments and the protection against salt and wind on the facades and terraces.
Payment schedule
As with most new builds on the Costa del Sol, you pay in instalments: a reservation deposit, a portion on signing the purchase contract and during construction, and the balance at the deed signing. Every payment before completion must be covered by a bank guarantee. We will send you the exact payment schedule for Vesta Mare through Privé.

Our honest verdict on Vesta Mare
Strengths
- Beach a 4-minute walk and port an 8-minute walk away.
- Supermarket an 8-minute walk away, so a car is not always needed.
- Roman remains in a dedicated interpretation centre, a story few developments can tell.
- Wide choice from 1 to 4 bedrooms, from €435,000.
- Seven of the nine homes have sea views.
Points to consider
- Price per m² is 64% above the Manilva new-build median.
- Completion not until March 2029, a wait of more than two years.
- Large development of 145 homes, so more neighbours and a busier pool.
- Small terraces in the smaller apartments, from 11 m².
- Archaeological remains can affect the schedule, so monitor construction closely.
Who is Vesta Mare right for?
Vesta Mare is made for those who want to use the beach every day and do everything on foot: breakfast at the port, a swim before lunch. It suits couples with a holiday home, but also families looking for a more spacious 4-bedroom home. If you want to move in soon or are focused on price per m², Manilva has cheaper new builds a little further from the sea.

Frequently asked questions about Vesta Mare
How far is Vesta Mare from the beach?

What happens to the Roman remains at Vesta Mare?
The Roman remains found on the site are being preserved and incorporated into an interpretation centre, which is open to residents and visitors.
Is Manilva a good place to live?
If you are looking for peace and a more affordable coast than Marbella, definitely. Around Castillo de la Duquesa you have the beach, port, restaurants and a supermarket within walking distance. For larger shops, you drive to Estepona.
When will Vesta Mare be completed?
Completion is scheduled for March 2029, so you are buying off-plan. We monitor construction and make sure your stage payments are covered by a bank guarantee.
Do I pay more if I buy Vesta Mare through Imagine Marbella?
No. You pay the same price as buying directly from the seller. Through us you also get independent advice, legal guidance and aftercare.
What costs come on top of the price of a new-build home?
In Andalusia, a new build carries 10% VAT (IVA) and 1.2% stamp duty (AJD), plus notary, land registry and lawyer's fees. For the most affordable home in Vesta Mare, that adds up to around 13.0%.
