Portamare: new apartments near Estepona marina from €459,700

Each home has an aerothermal system, which takes heat from the outside air instead of burning gas. It heats the water in a tank and also runs the heating and the air conditioning, which reach the rooms through ducts and grilles. The temperature is set from a home automation system.

Fitted units with handle-less doors in a pale beige or off-white finish, a porcelain-type worktop and a black mixer tap. The appliances are included: a three-zone induction hob, a combined oven and microwave, a 45 centimetre integrated dishwasher, a washer-dryer, a fridge and an extractor. There is also a connection for an American-style fridge.

Porcelain tiles that look like wood run through the whole home, in long planks of 130 by 22 centimetres, with a white lacquered skirting. The terraces are laid in a non-slip porcelain that matches the floor inside.

Tiled to full height, with the same wood-look floor. A wall-hung toilet with a dual flush, a wall-hung vanity unit with two drawers and a backlit mirror. The shower tray is dark grey and set flush with the floor, behind a black-framed glass screen, with a rain shower and a hand shower. The taps are black and limit the flow of water, to 5 litres a minute at the basin and under 9 in the shower.

Anthracite-grey PVC frames with low-emissivity double glazing, which has a thin coating on the glass that cuts the heat passing through it. Sliding doors open to the terraces, the windows open inwards from the side or tilt in from the top, and every room has a PVC roller shutter. The entrance door is armoured, with a three-point lock. Inside doors are solid and lacquered white, and the fitted wardrobes have white lacquered doors, a shelf and a hanging rail.

The building stands on a concrete raft, a single slab 70 centimetres thick under the whole building. The outside walls are 26 centimetres thick, built of solid brick with rock or glass wool insulation and finished in render in two colours. The walls between homes are solid brick with insulation and plasterboard on both sides. Waste pipes are insulated for sound and fixed on brackets that stop noise travelling through the structure.

Television, radio and telephone points in the living room, the kitchen and the bedrooms, a colour video entry phone, and LED lighting in the bathrooms, the kitchen and the hallways.

The basement garage has a polished concrete floor and painted walls with a coloured stripe. Each storeroom has a tiled floor and a double metal door with a ventilation grille. The entrance halls are laid in non-slip porcelain, and the shared areas are lit by LED lights that come on when someone passes.
