Horizon Jersey

Published 23rd August 2022

This landmark residential development in the heart of Jersey’s St Helier will deliver an exclusive collection of 280 one-, two- and three-bedroom waterside apartments and penthouses, and a new restaurant and retail quarter at the water’s edge offering 20,000 sq ft of commercial opportunities for local and national businesses. Continuing our successful relationship working with the Government of Jersey’s property development on the Esplanade Quarter site who are in JV partnership with Groupe Legendre, we are providing multidiscipline engineering services on this Skidmore, Owings and Merrill LLP (SOM International) designed iconic development.

Our structural and civils experts have designed the three nine-storey buildings which include a two-storey basement beneath the whole development. Constructed in an area of reclaimed land with a large tidal range and below ground water, the challenging basement level design required special consideration. Our specialists have provided design consultancy services for the contamination, hydrogeology and geotechnical aspects of the project, in addition to the design of the structure and highways on the site.

The site’s geometry also presented a challenge, with triangular buildings sitting in a fan arrangement to maximise sea views from apartments. This required careful structural design at first floor and podium level, particularly since the development had to accommodate the maximum number of parking bays, and much of the building transfers at ground floor level. Our Building Services team are providing client-side compliance monitoring services for the MEP services and lift installation, carrying out validation, technical reviews and site inspections.

Horizon is anticipated to be completed in 2023.
