Clearing the way for Europe's largest green wall

We are designing the temporary works for the demolition of the existing building over the live Network Rail Snow Hill tunnel, Holborn London, paving the way for this exciting new hotel construction designed by Sheppard Robson which will include Europe’s largest living green wall of 400,000 plants and a wild flower meadow on the roof. Working with Metro Deconstruction Service, also McAleer & Rushe and Michael Alexander Consulting Engineers.
Temporary works include checks and designs for the load-carrying capacity of the tunnel and for propping/foundations to take mobile crane and scaffold loading.


Only 1000 miles to go...

We are proud to be sponsoring the Atlantic Ambition crew as they row unsupported across the Atlantic in the Talisker Whisky Atlantic Challenge.

Celebrating the Simpson TWS merger

A great evening with clients and colleagues raising a glass to the coming together of Simpson and TWS. Between the two organisations we have 120 years of engineering consultancy experience. The long-term relationships we have with our clients have been key to this success and longevity - cause for celebration indeed!


Simpson TWS features in New Civil Engineer 

This article, covering our recent merger, appears in the December issue and on the NCE website. Great to see, in print, our story of the successful coming together of the two businesses. Through maintaining our strategy of great client service from a team of both experienced and developing professionals, the future looks bright with plans for continued growth.


Banksy artwork on the move at Art'Otel, Hoxton

When a new 20-storey cylindrical Art’Otel was being built in the Shoreditch Conservation Area it required the retention of two large Banksy artworks painted onto a rendered external wall.  Simpson TWS developed and designed the demolition methodology that allowed for the fragile artworks to be removed and relocated prior to the building’s demolition. Fabricated steel stillages clamped the panels to allow them to be lifted safely. In October 2019 the two artworks, one weighing 6t and the other 35t, were successfully freed from the building structure and transported by crane into their new locations.


Welcome to our new equity partners

We are delighted to welcome Gareth Crowther, Ian Rollinson and Chris Martin as equity partners in the practice. Their appointment represents a significant step in our growth plans as well as cementing a succession strategy for the combined business following our merger with TWS.

 We are also very pleased to announce that Jamie Munro has been promoted to Associate in the London office.  Jamie is taking a key role in supporting Chris Martin and the TWS team in developing the London presence following the merger.

 Congratulations all, exciting times!

"Please be Seated" : London Design Festival at Broadgate

TWS have given structural advice on a stunning art installation located in Broadgate, near Liverpool Street Station in the City of London. Created by Paul Cocksedge and built from recycled scaffolding planks, repurposed using innovative technology from White & White, the whole structure can be broken down and transformed into something completely different after the festival so nothing is wasted.

Great progress at Shiplake College Boathouse

The new boathouse and activity centre, in a beautiful position on the Thames, is due to be ready for use at Easter 2020 . The steel frame was erected in front of a sheet-piled retaining wall with a composite steel deck at the first floor. The cladding is currently being installed.



Gardiner Place Henley on Thames, takes shape

At Gardiner Place Mews (formerly Market Place Mews) the lightweight steel frame is being erected on site on a reinforced concrete podium slab. Simpson also provided the temporary works design for the base of the large luffing jib tower crane being used.



Joining forces with Taylor Whalley and Spyra


We are delighted to announce that Simpson Associates have acquired Taylor Whalley and Spyra.

TWS are an established and well-respected structural and civil engineering practice based in London, between the two practices we boast 120 years of engineering expertise!

We have enjoyed steady growth over recent years and the merger is a great opportunity to build on this, consolidate our presence in London and provide a robust succession strategy for TWS. Our current London operation will move into the TWS offices in the Barbican and we look forward to welcoming you for a visit.

The combining of resources significantly enhances the level of service we offer. TWS are well established with institutional, health care and local authority clients as well as complementing our current strengths. They have particular experience in the design of complex temporary works and central London basement construction and share our enthusiasm for delicate alterations to listed buildings.

Both practices have enormously experienced and high-quality staff and share a common ethos providing a flexible, client focussed, commercial service.

We look forward to working with you all in the future.

Stargazing Pods at Alton Towers complete

We designed a cost-effective solution for foundations to the pod units comprised of a compacted Type 1 material base with treated hardwood timber sleepers as bearing. The scheme utilises sustainable drainage techniques in the form of an attenuation basin for the disposal of surface water runoff. An earthworks analysis was undertaken to establish accurate positioning of the pod units based on the topography of the site whilst ensuring excavated material could be re-used onsite in accordance with the design of the proposed ground profile.


Simpson Team for Tough Mudder May 2019

Great teambuilding event for representatives from all our offices.

Notice the forced smiles in the 'after' photo!

Congratulations Chris!

Chris Martin completed his mammoth cycle ride from Greenwich, London to MIPIM, Cannes on 12th March 2019 in a team of 140 cyclists. He covered 1030km in total over 6 days and has raised £3160 for Coram, a charity supporting disadvantaged children.

There were a couple of tough days but the ride culminated in a fantastic final day. Starting off in the dark and cycling through the sunrise with a climb of 1600m followed by the descent into Cannes.  Spot Chris below - he is Simpson branded!


 Henley Office refurbished    

In the space of just 48 hours our Henley office is transformed. A fresh new look with accents of Simpson's green and blue and lots more space. Well done to the team involved!

The Principal Hotel, Russell Square

Following major refurbishment, The Principal Hotel in Russell Square has reopened. Formerly the Hotel Russell, the hotel was constructed in 1898 and designed by Charles Fitzroy Doll, the man famed for designing the dining room of the RMS Titanic (a design based on the Hotel Russell banquet hall). The building consists of a café, bar, restaurant and banquet hall, with the jewel at the centre of the Hotel being the Palm Court dining area with an external courtyard terrace at one end and an enclosed Winter Garden at the other, where original steel trusses were strengthened to support the spectacular ceiling and pendant lights.

Simpson Associates were structural and civil engineers for the project involving significant ground floor and basement alterations, including removal of a masonry wall up to 600mm thick; installation of a feature staircase offering elegant access to the lower ground floor conference suites; renovation of two existing lift shafts and provision of two additional lifts within the internal lightwell. The refurbishment involved the use of a variety of materials, including steel, timber, concrete and masonry.

The project recently won the prestigious New London Architecture Hotels and Hospitality Award.

The Principal Hotel has now been sold and is under new management, with a new name – the Kimpton Fitzroy.


Cheltenham Races November 2018

The sun shone on a team outing to the races and a great day was had by all. Suffice to say some left with heavier wallets than others! This photo taken on the winners' podium designed by our own Ian Rollinson.



Classical CD Release - Märchenbilder

Simpson Associates are enormously proud to have sponsored Tom Ellis and Elliott Perks’ first duo CD - Märchenbilder. The guitar and viola disk features a selection of works by great song composers including Schumann, Schubert and Wolf in new transcriptions, some of which have never been attempted before with guitar. The music was recorded at the Menuhin Hall earlier this year.

The duo took the repertoire on tour across the UK in June with Images Ballet Company, who choreographed the Schumann, and are now set to perform at numerous classical music festivals across Europe in 2019 including performances in Hambleden, London, Norway and Germany.

The music is available to stream on Spotify and Tidal or physical copies from following sites.



The eagerly awaited, biggest football match of this year has finally happened.

Simpson East (Henley & London offices) vs Henley West (Gloucester & Exeter offices). The match kicked off at 7pm in the Swindome, and the stands were packed with the travelling supporters. After around 15 minutes, Jack Hadley put the ball in the back of the net to put Simpson East in the lead. However a spinning ball managed to find it`s way into the Simpson East goal around 5 minutes later meaning the first half ended 1-1.

As the very close contest between the teams continued, Simpson East managed to go ahead again after another goal by Jack Hadley.

The score ended 2-1 to Simpson East, but it was a close match and could have gone either way. Simpson West now need to find a solution to end their losing streak in this important clash.

The trophy came home, back to the Henley office!

Staff from all offices came together once again to enjoy a wonderfully traditional English day out at the Henley Royal Regatta finals day on Sunday.



Two teams from Simpsons took part in the annual JLL Property Triathlon on Friday 29th June at Dorney Lake. After a hard-fought competition in 30-degree heat, Simpsons A took the win over Simpsons 1 by just over 4 minutes.

Mark Cradduck pulled out an early 3-minute lead over Ewan Wise in the lake, before tagging in Mike Beckly who extended the lead by another 3 minutes to Mark Regan on two wheels. In the final running leg, Sam Margrave-Jones pulled back a couple minutes on Chris Martin to finish with two respectable times (95th and 158th of 473 teams).

Training is already underway to improve upon this result next year!

Simpson Associates are pleased to support Merlin Entertainments through provision of civil and structural design services for their new castle themed family focussed hotel at Legoland Windsor.

This hybrid structural frame utilises composite steelwork, to form a transfer deck at first floor, to support a light gauge metal framed superstructure above. Castle themed cladding is formed from fibre reinforced insulated pre-cast concrete ‘sandwich’ panels, supported from the structural frame at each floor level.


Simpson Associates are working on a high end residential refurbishment and extension scheme, in West London.

The scheme includes the formation of a new basement under the existing building and a new roof terrace. The temporary support piles have been installed and levels reduced down to the new basement level with the new lower ground floor slab having been constructed.

Works are underway to form the basement slab and bring permanent support back up to the underside of the building.

While these works are being carried out, the new roof terrace has been constructed and super structure alterations carried out.
