Project Showcase - The Branch, Chipping Norton

The Branch is a multi-purpose community hub in Chipping Norton, Oxfordshire, operated by the charity, The Branch Trust. Created through the transformation of a former NatWest bank building, the project was developed to tackle social barriers, rural isolation and economic hardship within West Oxfordshire.

Setting

The new community hub provides support for mental health, loneliness, those that have been victims of domestic abuse and the young. Helping to build self-esteem, improve school attendance rates and open up career opportunities.

The building was purchased in 2019. Over decades, the property had been extended and remodelled — most significantly during the 1980s when it became Chipping Norton’s NatWest Branch. These alterations left behind a fragmented internal layout that no longer suited modern community needs.

The redevelopment aimed to create a more intuitive flow through the building, improving accessibility and extending the rear of the property to form a welcoming community hall.

However, this was far from straightforward.

The building’s mixed history, coupled with Chipping Norton’s sloping geology, meant significant intervention was required to rationalise levels and achieve accessible thresholds throughout the ground floor and basement.

The challenge

Complex ground conditions, historic fabric, neighbouring properties and restricted access all combined to make The Branch one of the most unique projects SOLID has delivered.

The only construction access available was through the original front door of the former bank — directly onto the busy Market Place.

Understanding the building’s evolution was essential in informing the structural strategy.

Initial proposals were developed through:

  • Detailed investigations into the existing structure

  • Archive drawings obtained by SOLID from Oxford Architects, who completed the NatWest refurbishment in 1984

  • Historic analysis of alterations made over time

  • Geotechnical investigations to assess ground conditions and inform foundation design

An initial site investigation in February 2021 identified difficult ground conditions, resulting in further investigations being required before structural solutions could be finalised.

A historic building

16 Market Place is a Grade II* listed property, with ownership records dating back to the 1770s.

Across its lifetime, the building has served multiple purposes:

  • Residence of merchants and bankers

  • Home to a successful drapery business

  • Department store ownership in the late 1800s

  • Boarding house by the 1930s

  • National Provincial Bank, later NatWest, from the 1950s onwards, closing in 2018

Centuries of adaptation left behind a complex structure requiring careful intervention to preserve historic character while enabling future use

Difficult access

Construction logistics quickly became one of the project’s biggest constraints.

Rear access was only possible through neighbouring land, whilst adjoining properties remained occupied throughout the works:

  • No.17 High Street — retail with residential accommodation above

  • No.15 High Street — residential dwelling

Internally, the building operated across multiple levels, with significant changes in floor heights throughout.

Party wall considerations and neighbouring constraints ultimately meant the project had to be delivered through the front entrance of the former bank.

Everything followed the same route.

Challenging ground conditions

Further investigations uncovered two major concerns:

  • Proposed underpinning works risked causing approximately 20mm of long-term settlement over 20 years

  • Shrinkable clay beneath the extension footprint created long-term heave risks following tree removal

These findings significantly influenced the structural approach.

The solutions

Several structural options were explored, including internal piling and ground injection grouting beneath existing walls.

Ground injection grouting ultimately informed a wider value engineering exercise, helping simplify interventions whilst maintaining performance.

Key design adaptations included:

  • Reducing altered floor areas to the building’s central zone only

  • Retaining perimeter levels where possible

  • Avoiding highways approvals by limiting interventions at street level

  • Implementing building monitoring systems throughout construction

Monitoring trigger values were exceeded at points during the project, allowing sequencing to be adjusted and movement carefully managed.

Further party wall constraints with neighbouring properties resulted in boundary realignments and restrictions on reinforced concrete placement

Building through the front door

The rear extension was delivered using:

  • Steel frame construction

  • Reinforced ground beams

  • Piled foundations designed to address shrinkable clay and long-term heave risks

All major construction elements entered via the original front entrance.

Including:

  • Piling rigs

  • Structural steelwork

  • Concrete deliveries

  • Crane access equipment

The extension steel frame itself consisted of:

  • 11.4 tonnes of steel

  • 599 fittings (plates)

  • 202 steel sections

  • 177 assemblies

  • 947 bolts

Every component was transported through the existing building via trolley systems and temporary ramps. Even the spider crane followed the same route before emerging at the rear!

Temporary works and structural intervention

Delivering the project required significant temporary works and carefully sequenced construction methodologies to enable structural reconfiguration.

As with many historic refurbishments, uncovering unknown conditions formed part of the process.

Alongside creating new spaces, SOLID introduced targeted structural interventions to:

  • Support reconfiguration works

  • Strengthen existing defects

  • Improve long-term performance

  • Preserve historic character where possible

The completion of the building is only the beginning

The Branch officially opened in February 2024.

Since completion, the building has become an active community hub supporting a wide range of initiatives, including:

  • Connect Café

  • Cookery classes

  • Support groups

  • Mentoring programmes

  • Foodbank projects

  • Co-working spaces

  • Drop-in sessions

  • Gardening clubs

  • Financial advice services

  • Nurture groups

The impact is already significant.

SOLID continues to support The Branch through the Business Club, helping sustain the charity’s long-term vision.

If every town had a Branch, communities across the country would be stronger for it.
