Red Lion Street

London, 20 Red Lion Street

Extension and refurbishment of Central London office building

In 2015, Mayfair Capital acquired 20 Red Lion Street, a seven-story Central London office building, originally developed in 1955. The building had formerly been subject to several minor refurbishments but provided Mayfair Capital with the opportunity to create top quality, sustainable accommodation commensurate with the demands of the modern occupier.

When the majority tenant chose to terminate its lease at expiry in 2017, we used Landlord and Tenant Act powers to compensate the remaining tenant and secure vacant possession.  This enabled us to proceed with a comprehensive refurbishment, including extending both wings to the rear and adding an additional sixth floor. By the time the works had completed in January 2020, key highlights and improvements included:

Key highlights:

  • EPC improved from E to A
  • BREEAM ‘Very Good’ on refurbishment and ‘Excellent’ on new build
  • Solar panels with generated electricity used to offset the building’s consumption
  • Green roof and five new amenity roof terraces


Amenities, health and wellbeing and accessibility

  • 42 secure cycle storage spaces and servicing facilities with LED lighting and motion sensors
  • Changing rooms with towel facilities and an additional locker room
  • Seven new showers
  • 84 lockers
  • Drying cupboard for cyclists
  • Staircase accessible immediately off the reception to encourage use of stairs instead of lifts
  • Improved, ramp free disabled access


  • Increased natural light through new energy efficient curtain walling with reduced solar gain and increased thermal efficiency
  • Thermal zoning and control throughout
  • Installation of a new BMS to enable more efficient running of the heating/cooling and hot water systems and reduced CO2 emissions
  • Energy efficient VRF air conditioning
  • Low heat output LED lighting with PIR and daylight sensors
  • Sub metering, linked to the BMS, to ensure that tenants can monitor and improve their energy efficiency
  • Destination control lifts improving efficiency


  • Reduced flow toilets and sensor taps
  • Leak detection to mains supply and each sanitary zone

Construction and materials

  • Sustainably sourced timber
  • Recycling of non-hazardous waste from the refurbishment – 94% diverted from landfill

Solihull, Trinity Court

2 Trinity Court is a 33,000 square foot, modern office property that was built in 1999 and provides accommodation over basement, ground and two upper floors.

We acquired the asset in 2016 with 2.5 years unexpired on the lease as it occupies a very attractive location adjacent to Birmingham airport, Birmingham International Railway Station and junction 6 of the M42.

We were aware that the M&E equipment in the property was close to the end of its economic life and that the EPC of E was poor (E-114). The property has recently been refurbished to completely replace the M&E and also enhance the amenity and sustainability credentials of the building:

  • A new entrance area has been created incorporating a new canopy, improved disabled access and external steps with bike wheeling ramp.
  • New basement cycle storage facilities with 30 secure storage spaces and 30 lockers.
  • Existing shower facilities within the building have been refurbished and extended to provide four showers and more locker space.
  • A new deck, accessed from the building at ground floor level and extending out over the car park, provides attractive breakout space for occupiers with views over the adjoining lake.
  • Four electric vehicle charging points have also been provided.

The new M&E incorporates:

  • Energy efficient VRF air conditioning.
  • Suspended ceilings with energy efficient LED lighting and PIR sensors.
  • High-efficiency sanitary ware that will reduce water usage.

Following completion of the refurbishment, the EPC has improved to B-45.

Leeds 2 Brewery Wharf

Leeds, 2 Brewery Wharf

Developed in 2004, 2 Brewery Wharf provides modern office accommodation over basement, ground and three upper floors. We acquired the property as part of a portfolio in 2013 with the intention of improving it over time and at purchase the property had an EPC rating of E-108.

Following the vacation of the second floor, we had the opportunity to undertake a refurbishment of the office space and common parts. The refurbishment included:

  • A new Building Management System (BMS) has been installed throughout the property to permit more efficient running of the boilers, chiller and air handling units.
  • Control of individual air conditioning units on each floor which will improve efficiency and reduce energy usage.
  • We have replaced the dated fluorescent and halogen lights with energy efficient LED lights within the second floor, WC's, stairs and lobbies.
  • Incorporated more efficient WC cistern flushing systems and low flow water fixtures.
  • Addition of a green wall in the reception.
  • Refurbished the two existing showers.
  • Installed new lockers and drying cupboard to encourage cycling provide attractive amenities for occupiers.

The new EPC rating for the refurbished floor has been substantially improved to C-57. In selecting our contractor, we ensured their sustainability approach and policies are in alignment with Mayfair Capital’s Responsible Property Investment ambitions. We have also sought to maximise recycling and re-use of materials. In total, 95% of the waste was reused or recycled.
