Housing type in Montealina

Semi-detached chalets with shared and private gardens

Montealina is a development of good-sized semi-detached chalets, each with its own garden and well-kept communal areas, strongly geared towards families seeking peace and quiet without giving up space. Being semi-detached makes energy efficiency and insulation between properties especially relevant: a poorly tuned climate-control system in one home can also show up in the neighbouring property's consumption. We design every installation with that construction detail in mind.

Climate control

Efficiency across the party wall too

In Montealina's semi-detached homes, an air-source heat pump with underfloor heating and cooling delivers very even comfort between floors, with energy consumption that stands out particularly when compared with old gas or electric systems.

We position and sound-damp the outdoor unit with the neighbouring property in mind, avoiding noise or vibration that could carry through the party wall.

Electrical

Electrics tailored to a semi-detached home

Installing an EV charging point in the garage of a Montealina semi-detached home, to ITC-BT-52 standards, usually requires first reviewing the property's contracted power and, where applicable, arranging the electrical certificate.

We complete the installation with low-consumption LED lighting and simple home automation, designed for comfortable everyday use with no technical know-how required.

A common case in Montealina

In Montealina's semi-detached homes we often see that one property's climate-control system was installed by simply copying the neighbour's, without accounting for differences in orientation or actual use between the two homes. Tailoring the system to the specific property, rather than the one next door, usually gives a much better result.

A well-sealed house, air that doesn't renew itself

Cause: Montealina's newer, well-insulated homes hold temperature better, but they also hold onto moisture and stale air if they lack proper mechanical ventilation.
Effect: Condensation appears on windows, or bedrooms feel stuffy, especially with the house closed up in winter.
Prevention: Add or review a controlled mechanical ventilation system matched to the home's level of insulation.
ANNA's diagnosis: ANNA assesses the home's ventilation as part of the technical diagnostic, not just its climate control.
