5 EXECUTIVE SUMMARY The significant refurbishment and redesign of Milton Hall by Milton Hall Estates was a privately funded venture by its owners to reinvigorate very tired and outdated office space. The brief was to take the Grade 2 Listed Georgian Hall and produce high end serviced office accommodation, it needed to be designed to attract small to medium sized companies keen to have an office with character in the Cambridge area. Milton Hall was built for the Reverend Samuel Knight around 1790; its design was inspired by Sir John Soane s architecture and the grounds were laid out to the design of Humphrey Repton. Significant historical research was embarked upon to support the Listed Building Application and wherever possible this was used to inform the specification of the redesign. The site had been significantly altered on 2 occasions, once in the 1960 s when 2 rather uninspiring office blocks were built and again in the 1980 s when an unsympathetic updating of the link building was approved as well as significant structural alterations to the Hall itself. Upon first viewing the buildings were rabbit warren like and as such the most significant task was to create clear and visible access for all users, this needed to be done whilst respecting the remaining heritage of the Hall and keeping close scrutiny on the budget.

10 PROJECT AIMS & ENTERPRISE The main aim of the interior design was to build on the high level of expectation experienced outside the building, showcasing the historical fabric where possible. The design therefore uses the inherent beauty of Georgian architecture as inspiration whilst introducing contemporary modernisation where necessary. The significant structural alterations to all 4 floors in the 1980 s adversely affected the grandeur of the original spaces reducing the journey through the building to a series of uninspiring dark lobbies with outdated accommodation at the end. Two original internal staircases had been removed, domestic accommodation installed on the 2nd floor and extensive basement excavations meant that the building needed to be reinterpreted for use as serviced offices. The ground floor entrance has now been re-modelled to create an impressive reception, its Georgian archways provide glimpses of the beautiful staircase and doorways beyond and a sumptuous broadloom carpet runs throughout the stairwell, new porcelain floors add a contemporary twist to the hallway and silk swags and tails frame the windows. During the research phase of the project an original silk wallpaper invoice was uncovered, this provided inspiration for the colour palette chosen. Green & Yellow Rooms have been reintroduced along with more modern supporting greys and blues. New arched doorways have been installed to the first floor realigning the symmetry destroyed in the 1980 s and padded lambrequins have been added to complement the Georgian windows in the office spaces in the Hall. The 1960 s buildings have been updated to match but with a more contemporary partition and door specification and air-conditioning. A new conservatory, French windows and glazed basement doors now allow access to the beautiful gardens from breakout spaces at the rear of the building and new hexagonal roof lights wash the meeting facilities with day light in the link building.

14 UTILITY OF PROJECT The design brief was to provide high end serviced office accommodation. Multi-occupancy of the buildings needed to be supported throughout with shared facilities being located at regular intervals. Bookable meeting rooms have been provided on the ground floor and in the basement, unisex toilets, showers and disabled facilities have been provided at a very high standard and well-appointed teapoints are also located on each level. The main staircase and lobby in the hall forms the protected fire escape for all 3 floors above ground level and as such creates the only barrier along the winding corridor throughout the facility. All other 12m fire doors are on a fail close system and remain generally open. Signage has been designed allowing tenants to personalise the entrance to their accommodation and maps are to be located in central locations informing tenants and visitors of the various locations of facilities. The conservation officer requested that the ceilings in the hall be respected and in order to comply the lighting design is based primarily on freestanding/desk mounted uplighters. The Waldmann light specified has integrated presence and daylight sensors which meant that, apart from emergency fittings, the original ceilings in the hall could remain generally untouched. Fixed meeting rooms are suited in to match with Waldmann fittings and corridors are lit more traditionally with LED downlights and wall lights. The lettable spaces have been designed to maximum occupancy, with services to suit, however these layouts can be altered to individual requirements. In order to future proof the facility and to attract local technology companies, the building has been completely rewired both electrically and with cat 6 data infrastructure. A new fire alarm system has been also been installed and the security system has been specially designed for use with multi-occupancy tenants.

17 VALUE, COST & PROGRAMME There were a number of specific initiatives that added value. As the development was designed to be serviced offices, the client/landlord was considered to be the main stakeholder although all potential tenants will also be stakeholders, value has been added for all stakeholders and potential stakelholders. The more modern parts of the building, that are significantly affected by fluctuations in outside air temperature, now have the benefit of heat recovery HVAC to avoid the need to open the windows. The older Georgian part of the building has the original sash windows, these have been restored so that the upper sashes are operable, re-creating natural air circulation as per the original design. As discussed the Conservation Officer was very keen not to disturb the original ceilings so a free standing lighting solution was designed. Each fitting has an independent motion and daylight sensor eliminating the need for any lighting circuits. The scheme saved approximately 15k of initial electrical work and will provide running cost savings over time as lights automatically dim according to the amount of natural light available, they also and switch off in unoccupied spaces. This was considered of particular benefit in a multi-tenanted space where control of energy consumption is difficult. Door Elevations and Reception Desk Elevation (1:100@A4)
