Old Admiralty Buildings

The Old Admiralty in Whitehall, a site of historical renown once inhabited by Sir Winston Churchill and Ian Fleming. Working extensively with English Heritage-listed features, careful consideration was given throughout the restoration project whilst works were carried out across multi-disciplines of construction.
Throughout the programme, TSB were called upon by various on-site 3rd party contractors to carry out electrical works, Asbestos shadow vac drilling, decoration and making good on their behalf, which added to TSBs already heavy workload, yet had to all be completed within the same timeframe in the shared interest of delivering a high level of service.
As the project unfolded towards the completion stage, the client and consultants decided to add further works which was required to be delivered within the agreed date of 1st of April. This was studied comprehensively by site supervisors and the dedicated project manager and a decision was reached to take on the extra work of which TSB completed above and beyond clients initial expectations.


TSB prides itself with a talented multi trade in house team that can self deliver small to multi-million pound projects within the building industry, all the while keeping communication at the forefront of their day to day working structure.

With this level of commitment to collaborate from the top down from director, to project manager through to every single engineer, it was the most vital component which allowed TSB to not only deliver within a tight timeframe, but to also complete it to industries highest building standards.


Delivering the highest of standards across multiple disciplines within a prestigious Grade II listed building all the while managing incredibly tight budgetary and time constraints of approximately 6 weeks. Over 20 skilled TSB engineers, joiners, decorators and electricians were allocated to the project including site supervisors and a project manager to fully self deliver every aspect of this exciting yet challenging project.

Throughout the programme, our site supervisors and project manager liaised directly with the client updating them of daily progress, meetings with senior on site and external consultants ensuring TSB were following the strict scope of works including Heritage for the listed aspects of the works, and also the clients architects & interior designers in order to meet their overall vision. In house design proposals for various joinery works were also submitted and agreed with the architects which then formed part of the successful installation of the Tea Point / Break out area refurbishment.

Asbestos Drilling

TSB had ensured they had fully trained engineers that can deal with Asbestos and the activities and responsibilities that come with asbestos in listed buildings. Asbestos registers were checked, strict H&S protocols followed and the successful confinement and shadow vac drilling of walls / ceilings were carried out in connection with external consultants that would validate air purity and safety after every drill to complete various works around the building.
In connection with these works, TSB carried out the installation of over 160 customised whiteboards of varying sizes, bespoke metal wire frames for the hanging of valuable artwork within the art gallery section of the building, access for plumbing routes through walls, AV and electrical installations via chasing and core holes, including the hanging of digital signage across all floors.

Flooring Installations

TSB had a team dedicated to install over 1,500 sq.m of new carpet, vinyl and tiling across multiple office rooms, open areas, corridors, breakout areas and lower ground specialist rooms.
This included the full strip out of existing, storage, disposal, and most importantly pin-point co-ordination between client, contractors and organisers within the building to ensure the programme of works was followed without any delays.
Further flooring installations of carpet tiles were required to make good around floor boxes moves and changes, and ad-hoc making good of 3rd party contractors work.

Joinery And French Polishing

The building required extensive works to existing 100+ year old heritage doors and frames that were in dire need of making good, adjustments, re-hanging and French polishing, to bring the Grade II listed doors to their former glory. This included re-handing of the doors, installation of drop seals, adding extra lipping to create tighter gaps between door and floor and acoustic bat wing seals to frames for acoustic improvements. Brass iron-mongery had to be matched to fit its surrounding doors from heritage stores within the buildings basement, and a record kept to state which fixture was paired with which door and photographic evidence to suit.
This required a level of trust and meticulous record keeping by the TSB engineers which simplified the process for the client. Multiple pattresses were also installed to re-enforce plasterboard walls which was required by 3rd party contractors for the installation of digital signage screens across all floors, including the making good and decoration thereafter. Finally partitions and nibs were required to create smaller and newer spaces within existing space planning and were executed with precision including decoration works to match.

Tea Points And Plumbing

The in-house design team liaised with the architects and interior designers to agree submitted design proposals for the addition and upgrades of tea point areas throughout the building which were then executed by TSB's workshop and installed by multiple talented joiners. The tea points were installed with stone worktops templated and cut to size, tailored timber base units, cupboards and cabinets which included installation of new plumbing, electrics, purified water systems, HW heaters, macerators, sinks and taps to meet the architects vision of a refreshed tea point / refreshment zone.
All disciplines including joiners, electricians, plumbers and fabric engineers worked harmoniously together and to a strict POW set by the project manager, leading to a successful installation of 19 new and upgraded tea points.

Floor Box Moves And Electrical Installations

Floor box moves and installations were part of the extensive electrical programme carried out by TSB's NICEIC accredited in-house electricians. The works also included isolations, commissioning of Fire Exit signage, powering AV equipment for clients incumbent AV suppliers and the running of new power and data cables where they were not previously available.

The electricians and their lead were working day and night allocating and re-allocating the required changes based on new space planning from moves and changes including weekly updates with the client ensuring all power and data is sufficient for the moving in staff.

Soundproofing – Doors, Ceiling, Wall Voids

Acoustic consultants were allocated to the project on behalf of the client of which TSB and it's project manager had to work closely with. This was to ensure that every level of the installation by the fabric engineers would meet and exceed the final result required to improve room acoustics and in turn create a level of privacy for government officials.
The consultants were involved in day to day dialogue with the project manager ensuring TSB were following exact instructions on scope and material usage within the walls and ceiling confines. For wall voids and back infills, a double stud was erected with a minimum gap of 175mm in between filled with dense rockwool, double soundbloc plasterboard finished off with shadow gap detail. For the high level ceiling voids in between rooms and corridors, double batts were used to sit flush with wall detail, and the void filled with rockwool sealed off with intumescent sealant. Doors with large gaps between floor and door also received additional lipping to narrow the gap, and a drop seal to sit flush with floor threshold strip.
This exercise ensured that any wall void, ceiling penetration and gaps within frame and door received the maximum level of soundproofing to deliver on the Acoustic consultants required decibel rating for privacy.


The level of works required at the building needed decorators with a fine eye to detail, and experience within Heritage environments, being mindful of the surrounding area. Decoration works were continuous throughout the project and followed all teams and 3rd party contractors to ensure existing walls where notice boards were taking down were made good and painted, access panels cut for plumbing and electrical work received new plasterboard, tape, joint and decorated.
Additionally heritage doors were refurbished in line with consultants guidelines, partition walls and nibs fully decorated to blend in within the surrounding space, and many more activities that were carried out to the highest level of standards expected, matching existing including following closely the paint specifications for each area from the buildings finishing schedule.
