Restaurant & Apartments Conversion, Lincoln College

CBG Consultants were delighted to deliver this prestigious development for Lincoln College on Oxford High Street. The project involved the conversion of a Grade II Listed former bank dating from 1866, into a new restaurant and upmarket apartments. The team were keen to restore and retain period features, such as an original ceiling discovered in the banking hall that was previously concealed. Bespoke M&E services strategies were developed to maximise the historic appeal of the spaces.

New services were provided throughout, including construction of a new lift. We designed the shell and core scheme and acted as technical advisors for Lincoln College, to review the proposed restaurant fitout by The Ivy. We worked closely with their fitout team to ensure mechanical and electrical services strategies were developed that would work within the confines of the site and defined tenant demises. Control of odours from cooking was a particular concern, with a scheme to mitigate these. The location of plant near to residential units required close scrutiny of acoustic performance also. Future maintenance and plant replacement strategies were developed and included within the Agreement for Lease.

Full design was undertaken for the apartments, with lighting, electrical services and air conditioning developed to a high standard specification. The residential development includes a new feature stair with bespoke suspended lighting, which links to the existing Alfred Street apartments.

 

Renewable Energy Feasibility Studies, National Trust

In 2012 the National Trust launched their Renewable Investment Energy Programme, committing over £30 million to halve their carbon emissions by 2020. CBG have worked with the Trust on at least 11 significant properties across the south of England. We have advised how the National Trust can utilise renewable energy sources to reduce these emissions.

The technologies we have considered include; biomass, solar PV, solar thermal, wind, combined heat and power, and heat pumps which can harness renewable energy from the ground, water or air.

Our feasibility assessment process includes detailed studies of the properties, liaising with staff and stakeholders, radiator surveys, load monitoring, and heat loss calculations, culminating in a comprehensive feasibility report that evolves to incorporate feedback from the Trust’s approval stages.

CBG have continued their project support through the tender process, providing tender return analysis and attending interviews. We undertake site visits throughout construction, as well as write inspection reports, and act as CDM Principal Designer.

 

Command Of The Heights, Fort Amherst, Chatham

CBG are working with Medway Council on an ambitious Heritage Lottery Fund scheme at Fort Amherst, Chatham.

The fort dates back to the Napoleonic wars, and is a Scheduled Ancient Monument. The vast site poses many logistical challenges, with a network of tunnels, barrier ditches and hilly terrain. The project includes the conversion of former gun casemates at the summit of the site into an open-air theatre; creation of a new visitor access to the site from the main road; installation of a new WC block and demolition of a former MOD office building to reinstate the historic lines of the lower site defences.

Engineering services include new power and water distribution across the site, M&E services to the theatre, landscape lighting, and diversion of a former UK Power Networks substation.

Christ Church Cathedral

CBG Consultants were appointed by Christ Church, for the phased renovation of the Cathedral in 2017.

Dating from the 12th Century, the Grade I Listed Cathedral was last rewired in the mid 1990s. A proposed project to clean and restore the high level building fabric gave the opportunity to renew electrical distribution and the lighting installation, which had become dated.

We worked closely with the Cathedral’s nominated lighting designer, and Purcell Architects, to develop the new electrical infrastructure proposals. This had to be installed over several phases of work whilst the Cathedral remained in use. Much of the servicing of the building is done using the high-level clerestory walkways. While these provide a convenient route, they also pose a risk to maintenance personnel, with access available only with safety harnesses to two people at a time. We developed a scheme to minimise the need to access these walkways, by locating the drivers and power supplies for the lighting system in central locations away from the clerestories. These are more likely to require future maintenance than the light fittings themselves.

We designed a new central battery emergency lighting system, bringing the building up to compliance with current regulations. Night time validation was undertaken to record delivered illuminance levels.

Phases 1 and 2 of the project are now complete, with the design of Phases 3 and 4 due to start later in 2019.

Coach House – Longstowe Hall, Cambridgeshire

Conversion of a former coach house into a high quality wedding venue.

The coach house is grade II listed and part of larger estate with a grade II listed manor house and landscaped gardens. The coach house is one of the earlier buildings on the estate and originally dates from the 1700s. The venue currently runs a marquee as a wedding venue through the summer months and the conversion of the coach house enables our client to improve their wedding offering.

CBG were commissioned to design the M&E installation which included ventilation, heating, domestic water, fire alarm, security and the lighting design. Given the remote location of the coach house back up power (generator) also had to be provided as power cuts can be more frequent and maintaining the venue during an event is imperative. Aesthetics were a very important consideration during the design to tie in with the high end image. Services routes were also a challenge to be overcome, as much of the void above the former stable area is inaccessible as it is inhabited by Bats.

 

Grade II Listed Manor House

Grade II listed manor house located in the middle of its own landscape.

Working closely with Smallwood Architects we have developed a full refurbishment design to an exceptionally high quality & standard, to include a remote energy centre to feed several buildings on the estate including ancillary buildings, cottages and swimming pool. The property will be a full integrated system with intelligent automated controls for all heating/cooling and audio visual.

Oxfordshire Castle & Manor House

Dating from the 15th Century, a very careful and detailed refurbishment and extension of this historic castle and manor house.

The extension includes a complete new wing incorporating reception rooms, ground hall, staircase, indoor pool & leisure facility, underground garage facility and extensive wine cellar.

A fully integrated and intelligently controlled house introducing the latest technology all set within a very traditional architectural aesthetics.

Grade II Listed Manor House

Full refurbishment and extension of existing Grade II Listed Manor house of approximately 12000 sq ft using high quality finishes and integrated mechanical and electrical services.

The Grade II listed Georgian Manor House has undergone extensive refurbishment including the building of a new indoor pool and leisure complex, full size cricket pitch and pavilion.

 

West Country Park House

Restoration of a West Country Park House. The 18th Century house was last refurbished in the 1950s, the project involves the sympathetic modernisation of mechanical and electrical services, along with redecoration of internal spaces and the inclusion of en-suite bathrooms.

The former staff quarters in the attic were converted into new guest accommodation. Existing fixtures and features were retained where possible, including 19th Century graffiti by a disgruntled servant. Infrastructure was upgraded across the site, with a new electrical supply provided to the stables and workshops.

Challenges included the removal of an unattractive external boiler flue added as part of the last refurbishment, and provision of new internal drainage.

Norris Museum, Cambridgeshire

CBG worked with Caroe Architecture on the Heritage Lottery Funded refurbishment and extension of the Norris Museum at St Ives.

The new facilities include a specialist archive store, flexible exhibition space, permanent display areas, an educational facility and new toilets. CBG completed the initial HLF Round 1 feasibility report and strategy, and were delighted to be subsequently selected to progress the Development phase of works.

Lighting has been designed to provide a contemporary and minimalist look, which works well with the historic building. An exception was made in the Herbert Norris replica study, where several of the original glass pendant lights from the old gallery were restored and re-used, to great effect. Within the temporary exhibition space, suspended track is used. This allows lighting to be easily adjusted when exhibits change. Daylight is managed to prevent over exposure of sensitive materials. Other electrical services such as small power are discreetly located, and coordinated with the extensive timber panelling.

Environmental control is provided using a relatively simple heating system, combined with dehumidification units. This keeps the running costs for the system down, whilst providing a stable environment for the artefacts.
