SPECULATION is growing over which businesses may open in a new city centre development.

The Edward Street Quarter, on the site of the former Amex House building just off Grand Parade, is set to be completed by summer next year.

Its six buildings will accommodate offices, retail and hospitality facilities as well as housing.

And now Property developer First Base is understood to have agreed its first lettings at the £120 million development.

Co-working operator X+why will take 28,000 sq ft of flexible office space at the scheme, which will mark its first location outside of London, according to magazine Property Week.

Meanwhile, gym and fitness operator Hybrid fitness is understood to be opening its fourth UK gym at the development, taking around 7,300 sq ft

Independent Spanish restaurant Espina is also set to take a 1,000 sq ft restaurant.

The Edward Street Quarter aims to provide 125,000 sq ft of flexible space for Brighton’s digital and creative sectors and wider corporate community.

Developers say this would make the project the largest provision of workspace to be delivered in the city since 1993.

It is hoped the space will "attract creative businesses, ambitious start-ups, entrepreneurs and established companies".

Approximately 20,000 sq ft has also been set aside for retailers, leisure, and hospitality and 168 new homes, comprising a mix of private and affordable units, will also be available.

The development includes design features to boost mental and physical wellbeing as well as three public green spaces, heavily planted with mature trees and an edible garden full of herbs.

Earlier this month, construction on the tallest building in the development was completed.

A topping out ceremony marking the placing of the final beam was held atop the 101 ft building with Brighton and Hove city councillors and businesses owners among the guests.
