The development is an 12 storey building comprising 13,475m2 (NIA) of office area over basement to eleventh floor and 141m2 of retail area located on ground floor.






Apex Tower, located next to New Malden train station is a 15-storey office development. The reception area at ground level has been enlarged to provide a prestigious reception area which then leads to a commuter facility with unisex showers and a drying room. The extension to the ground floor provides a green roof space to add some biodiversity to the scheme.
The refurbished office floors are served by four new lifts and two staircases. There are three Cat B office suites provided at the 14th floor with the 15th floor refurbished as a communal space with a breakout area and bookable meeting rooms.
The building itself is served by a condenser water loop which connects to gas fired boilers and dry air coolers for heating and heat rejection. This loop is served by water-cooled heat pumps which are located at the 15th floor. From each heat pump refrigerant is used to serve floor mounted fan coil units within the office areas. Each fan coil unit is provided with its own architectural casing to meet the desired aesthetic of the building.
On the office floors the existing coffer ceiling has been retained with suspended linear luminaire fittings to meet the required illumination levels which works to create an aesthetic with the mechanical services which route around the core. The building is provided with two air handling units, each with heat recovery at roof level which provide the fresh air into the offices along with ventilation columns on the perimeter of the building serving low level grilles.
The refurbishment works is targeting BREEAM RFO ‘Very Good’ and has achieved an Energy Performance Certification rating of ‘B’.

Watkins Payne was involved with the Fetter Yard project on 86 Fetter Lane for 5 years and provided the MEP services design and BREEAM assessment.

The building at 1 New Burlington Place has been redeveloped to offer 183,000ft² of high quality office and retail accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering and energy consultancy to achieve an EPC A rating. We also supplied BREEAM services and achieved a BREEAM Excellent rating for the development.

Watkins Payne carried out the Independent Design Review role for Seal House, a commercial office development, located in central London.

The project also involved the refurbishment of the reception space and improvement of the cycle store entrance and wayfinding at basement level.

10 Fetter Lane needed some freshening up for marketing, so the first floor offices were to be modernised as a show stopper with a contemporary exposed services design and improved floor to ceiling height.
