Description
NO BUYER'S AGENCY FEE. The buyer pays no agency commission: the fee is borne in full by the seller.
Portopiccolo, Sistiana. On the top floor of one of the buildings that face the village square, a penthouse of 156 sqm arranged over several levels, with a terrace of about 25 sqm looking out to sea. The position commands the Gulf of Trieste and almost every window faces the water: the view is part of the house at every hour of the day.
The living area
A single open plan, designed for this apartment. Exposed beams, added at the owner's request, and an increased ceiling height give the level air and character; the modern, fully integrated kitchen opens onto the terrace, which becomes the extra room for lunches and summer evenings.
The sleeping area
A double bedroom with dressing room and a large shower bathroom, a single bedroom and, on the upper level, a further space with a double bed, suited to guests or to an additional private area. Four rooms and three bathrooms in all. The materials and the pale tones hold together a quiet atmosphere, in keeping with the marine setting.
Systems and efficiency
Centralised underfloor heating, centralised heating and cooling, mechanical ventilation and domestic hot water production. The building dates from 2013. The unit's energy performance certificate gives class A3 with an EPgl,nren of 48.89 kWh/sqm per year (EPC no. 3200100008625, valid until 16 April 2035).
Parking, storage and access
Two covered parking spaces and a generous cellar. Electric gates lead straight into the garage and from there the lift reaches the floor of the apartment: private, sheltered access in every season. Communal swimming pool.
The setting
Bars, restaurants, boutiques and the marina are at the foot of the building, yet the penthouse stays set apart from the traffic of the square.
Running costs
Service charges € 500 per month. Estimated annual waste tax (TARI) € 276.
Land registry: Municipality of Duino-Aurisina, section C, sheet 7, parcel 2281, subaltern 2405.

How we used AI in these photos and in the video
All 40 photos retouched with AI: 1 edited and 2 simulations, marked on the photo; the rest in light and colour only. The viewing remains the only reference.
How we edited them
The photographs in this listing are 33 shots by a professional photographer, taken on 18 November 2025 and already developed with an ordinary retouch (some by merging several exposures), and 6 views of the Portopiccolo village and marina. All 39 of them (40 images are published because the cover repeats a photograph of the terrace) were passed through a generative image model (Google's Nano Banana family, used via the Higgsfield platform) for a single purpose: to brighten them and correct light and colour. Nothing was requested to be removed or added.
In 36 photographs the model stopped at the light: in two kitchen photographs it rendered the window blind backlit, and in one of the two it also removed the patches of sunlight on the wall and worktop. In three photographs, however, the model changed what can be seen outside, and we declare it: in the kitchen with the fridge and ovens on the left it raised the blind on the far window, which is lowered in the starting photograph, and invented the view behind it (sea, rocks, a house), as well as the sea in the door on the right, which is white with light in the starting photograph; in the bedroom with the open wardrobe it turned the window plain white, whereas in the starting photograph it shows an outside wall, a pillar and trees; in the sunset from the terrace under the pergola it added clouds to a part of the sky that was clear. Even where it only worked on the light, a generative model does not copy the fine grain of the image but reconstructs it: the texture of rock, plaster, foliage and water, and the most distant details of the views, are plausible, not photographed.
Nothing else was modified: dimensions, ceiling heights, openings, floors, windows and doors, installations, finishes and furniture are as photographed, and no defect has been softened or hidden: the grey weathering of the terrace wood, the stains on the stone threshold of the French window and the marks on the glass have been left as they are. On the model's output only the adjustments of an ordinary retouch were made: brightness, cropping to the original format, sharpening. The starting photographs, as they were before the AI step, are available on request; the viewing remains the only reference for the actual condition of the property.
