Main Kitchens – Magdalene College, Cambridge

Client: The Master and Fellows of Magdalene College, CambridgeDB&P's Services: Building Services Consultant Engineers

Magdalene College has an excellent reputation for providing high quality cuisine worthy of the most prestigious of occasions; with the enviable choice of two stunning dining rooms - The Hall, once a 16th century former monastery where dining is still held in complete candlelight, and the Parlour which was once the Master’s drawing room. To assist in maintaining such high catering standards the College duly embarked on a major scheme to completely refurbish and extend the original kitchens; which having provided commendable service over a 50-year period were in need of some greatly deserved attention.  After much consultation with the College’s management and experienced catering staff, the “Team” designed and delivered a modern, fully equipped kitchen with state-of-the-art cooking facilities.

Of major consideration was the Grade 1 listed status of the building and the conditions imposed to negate all adverse elements of the M&E services in terms of the visual impact that any equipment / plant would have on the East façade of the College.  This is particularly relevant since the view of the College from Magdalene Bridge is probably one of the most photographed scenes in Cambridge. In this respect the kitchen supply air handling units, extract fans and associated ductwork systems are carefully concealed behind the cleverly designed parapet wall, the line of which blends sympathetically into the contours of the College.  The issues of noise and odour, both much prevalent in a commercial grade kitchen, posed similar problems; however, by specifying the appropriate and good quality equipment these problems have successfully been negated.

Catering Facilities – Arthur Rank Hospice, Cambridge

Client: Arthur Rank Hospice CharityDB&P's Services: Building Services Consultant Engineers

Arthur Rank House was the concept of Dr David Bratherton, a therapeutic radiologist at Addenbrookes Hospital, who determined to build a specialist hospital for patients in the final stages of terminal illness. The original hospital was opened in May 1981 at the Brookfield’s site in Cambridge and provided essential services and exemplary care to thousands of patients over a period of 35 years. However, it had become clear that the building was unable to cope with the everincreasing demands on its services and the fact that many of the key facilities that were no longer fit for purpose.

The decision was taken in 2013 to construct a state-of-the-art hospice on the outskirts of Cambridge, set in a green and tranquil site with good transport access. The hospice was handed over to Arthur Rank’s Team in 2016 – two weeks ahead of programme and on budget. The building was very quickly in full operation – providing a spacious, attractive and therapeutic environment: designed with great consideration for the patient’s needs with vastly improved amenities. The in-house catering facilities provide a comprehensive range of meals, designed to satisfy specialist medical, ethnic and personal dietary requirements. It was deemed important that the patients, visiting friends and relatives alike could share in the food preparation and cooking experience; subsequently there is a viewing section between the café / dining room and the kitchen. As consequence of this open plan aspect, the mechanical ventilation system has been significantly simplified – extract air is drawn away directly above the cooking and pot wash areas via a range of induction canopies, the filtered / tempered supply (make-up) air is discharged into the café and dining room to provide a highly efficient cross flow ventilation system. In this respect, the complexity of associated ductwork has been reduced which has in turn resulted in increased ceiling heights adding to the open and airy aspect of the rooms, in turn creating a very relaxing environment.

Main Kitchens – Corpus Christi, Cambridge

Client: Corpus Christi, CambridgeDB&P's Services: Building Services Consultant Engineers

The existing finishes and fabric were stripped back to the bare structure of the building thus facilitating much needed alterations to improve access routes and ceiling heights. Unfortunately, the extensive refurbishment works unveiled several key structural issues within the building; not least a 12ft high medieval wall which was found to be extremely precarious / vulnerable due to a distinct lack of support. To eliminate the initial problem, a framework of structural steelwork was introduced. However, the additional steels severely intruded on the proposed location for the main kitchen supply and extract ductwork with significant repercussions in terms of routing the ductwork through the building to roof level. It is a credit to the Design Team, the Contractor and the patience of the Client, that by working closely and in full consultation a viable solution was derived without serious cost implications or delays to the programme. Of major consideration was the Grade 1 listed status of the building and the conditions imposed to negate all adverse elements of the M&E services in terms of the visual impact that any equipment / plant would have on the College. In particular the close proximity of the mechanical supply air handling unit / main kitchen extract fan to the Bursar’s private quarters and the neighbouring Department of History. The issues of noise and odour, both much prevalent in a commercial grade kitchen, were negated by specifying appropriate and good quality equipment. Due to the limited ceiling height within the main cooking area, the use of conventional supply / extract induction hoods was deemed to be impracticable and preference subsequently given to a fully-ventilated ceiling arrangement complete with banks of extract grilles/filters, the later operating in conjunction with U V ozone systems designed to eliminate grease carry-over into the ductwork.

Phase 1A of Jesus College’s West Court project comprises the refurbishment of the original Wesley House development. Re-acquired by Jesus College from Wesley Theological College, the buildings have been transformed to provide high quality student welfare amenities – Common Rooms, Café, Party Room with full bar and micro-brewery. The associated catering facilities have been designed to provide an extensive array of meal options for the students and visiting delegates; ranging from formal dinners in the original Dining Hall, lunches and snacks in the new build Café to on-site brewed beer in the basement Party Room.

DB&P worked closely with the College’s representatives and Architect via a series of workshops to establish a comprehensive and definitive brief for the catering facilities – subsequently the team were able to approach the market with unambiguous / project specific requirements which significantly assisted with the ongoing design process and the need to maintain a cost competitiveness element. Of major consideration was the Grade 2 listed status of the building and the close proximity of the student rooms / delegate guest rooms in relation to the M&E plant; in particular the relatively substantial mechanical ventilation systems and the associated issues of noise and odour. In this respect the kitchen supply air handling units, extract fans and ductwork systems are located at roof level in a purpose-built acoustic compound. The primary plant has been carefully located to be indistinguishable to the lay person; equal consideration has been given to safe access to facilitate easy / unencumbered maintenance.
