Brief history

The tired 1980s 6-storey open plan office development is situated at a busy intersection of Bristol City Centre, at a crossroads that has recently undergone major improvement works, meaning that more traffic now flows towards the site. The pre-existing building had a basement car park and plant equipment within the roof space.

Vision

The vision was to redefine the city’s gateway by introducing a distinctive new building profile that seamlessly integrates into its surroundings. Enhancing the local environment as well as the internal workplace for the occupants. The extensions to the existing building offer 55,590 sq ft of space with the intention of creating high-quality workspaces that promote health and wellbeing through design.

Design Intent

We took a Retro-first approach with preservation, renovation and expansion being at the forefront of the design process. With the existing building in sound condition, retaining the structure and many of the façades ensured a highly sustainable development. The emphasis on innovation within the retrofit design allowed us to successfully craft an inviting and functional space that fosters collaboration and caters to hybrid working.

There was a collective drive to deliver from an ESG perspective to improve the original quality of the building, which meant that we considered the environmental and social impact of the building in our design and future use of the space.

Design Delivery

The design is thoughtfully flexible with the collaboration between architectural and engineering disciplines being fully coordinated. The ground floor is a blank canvas that can be changed to fit the evolving needs of the occupants; it comprises dynamic office spaces, a public café or a retail unit. The prominent position means they will be frequented often. The luxurious, relaxing and welcoming atmosphere that has been cultivated by the interiors begins when you enter the reception area, with the double ceiling height and natural light and continues into the generous WC provisions and office spaces throughout.

Sustainability

Excitingly the building is connected to the Bristol District Heat Network – actively contributing to the reduction of greenhouse gas emissions in our urban environment, aligning with efforts to address the pressing climate emergency.

The Retro-first approach exemplifies sustainable development and has allowed us to improve overall thermal performance, air permeability and energy efficiency. PV cells provide onsite renewable energy and the amount of carbon saved is 1,963 tonnes / 281kg CO2e / m2 GIA. Subsequently, the building has achieved:

Net Zero Carbon Building / 2 Star Fitwel Certification / Active Score Platinum / Platinum WiredScore / Outstanding BREEAM Rating / EPC A

User experience

The integration of technology into the building’s operation was undertaken to optimise user experience.

The lighting system utilises Organic Response Technology with an integrated sensor in every luminaire.

With boutique WCs, a basement car park with EV chargers and a Platinum ActiveScore rated cycle facility, we have considered ways in which the user experience can be maximised at every opportunity.

Wellbeing

The differing types of working areas that make up office spaces will improve people’s wellbeing and work-life balance.

Post Occupancy Evaluations will be completed by occupants to learn how the spaces are used and enjoyed.

During the construction, the local community was involved by extending our support for the local homeless population via the initiative ‘Leave a Coat, Take a Coat’ and promoting local causes such as Billy Chip; dedicated to assisting those in need.

Flexibility / Commerciality

The team have been mindful of the future refurbishment of the building; for example, the steel façade structure allows flexibility for alternative cladding solutions in the future and use of rational grid and glazing modules allows for replacement.

Another feature is flexible floor plates that can easily sub divided into 1, 2 or 3 units per floor – to suit the demand. Offering a variety of tenancy sizes with configurations that can be adapted throughout the lifespan of the building.

Our structural embodied carbon calculations for the primary structure achieve (at 105 kgCO2e/m2) a Structural Carbon Rating Scheme (SCORS) rating of A — meeting the SCORS, RIBA, and Low Energy Transformation Initiative (LETI) commercial targets set for 2030!"

Identity

This bold new presence in Victoria Street seeks to mimic the architecture of the area whilst updating the One Hundred building to encourage people to travel and to work there.

Concept Diagram

The initial concept diagram illustrates how the existing environment has been adapted and re-worked.

Elevations

This diagram shows the elevation from the Victoria Street view. A variety of window sizes have been used to elevate the building's street presence, establishing itself as a modern working environment. This transforms the building’s former dull presence to reflect that it is an exciting new hub for activity and fits in with the recent developments in the area.

Interior Design

The vision for the interior was to reflect the high-quality external finishes, whilst providing a welcoming atmosphere. Bringing in the ideas and concepts of the materials used on the outside cladding, with panels that adopt either a smooth or textured surface – which can be seen in the finishings on the inside.

Complicated retrofit of a previously unattractive building is really important as a gateway to Bristol. Boundary pushing, visually interesting development. Impressively carbon neutral too."
