Clement Windows Group

Hampstead Garden Suburb, in north London, is internationally recognised as one of the finest examples of early twentieth century domestic architecture and town planning. It was designated as a Conservation Area in 1968, and the older part of the Suburb was designated a ‘Conservation Area of Outstanding Architectural or Historic Interest’ in 1977.Clement developed the Brooking range of steel windows as sensitive replacements for existing fenestration in the Suburb. The new windows look incredibly similar to the original windows and doors, but offer much improved specification. The owner of this wonderful, detached red brick home chose Clement to manufacture and install the new bespoke steel doors and windows. The slim frames, coupled with handles polyester powder coated to match look perfectly in keeping with the character of the property.Clement Windows Group CEO, Peter Clement, said: “It has been a privilege for us to have enjoyed such a long association with the residents of the Hampstead Garden Suburb. We are proud of our reputation for high quality and innovation, which has been earned following hundreds of successful steel window and door installations at a variety of different properties in the Suburb - from Arts & Crafts to Art Deco to fine individual architect-designed homes. We look forward to being involved in many more projects in the area in the future.”

Abbey Mews was originally the carriage store and workshops for Laleham House, built in 1803 for the 2nd Earl of Lucan. It consists of eight freehold Mews houses set around a large courtyard. The estate was for some decades in the early 20th century let to the Catholic Church, acquiring its Abbey status as a Nunnery. The house was divided into apartments in 1981 by Barratt Developments and Abbey Mews was converted to Mews houses at the same time.When our client purchased their Grade II Listed home on the site, the windows were single glazed, probably dating from the 1950s. Understandably, the client wished for windows that were fit for purpose but also looked as close to the originals as possible. A number of alternative manufacturers products were considered, but the EB20 range was chosen, based on quality, price and Clement’s ability to provide a bespoke solution to cope with the intricate arched windows.Clement also manufactured an individual internal double door to replace a single door which divided the kitchen from the Conservatory. The new design, incorporating the slim frames of steel makes a really stunning feature.The client said: “Clement provided an excellent bespoke solution for our Grade II listed property, including individual templating of multiple arched windows with slight variations to ensure a perfect fit. This enabled us to satisfy Listed Building requirements, significantly improve energy efficiency - as well as open and close them in the normal way, a big improvement over the previous inconvenient and obstructive bottom-hinged configuration. Throughout the design and manufacturing process, Clement were proactive and cooperative. Installation was quick and clean. A few minor snags were promptly resolved. Considering the effort involved in a completely bespoke solution, they were also good value for money. The end result looks great and several neighbours already have or are considering using Clement.”

Clement Windows Group has been privileged to manufacture new steel windows and doors to replace the originals at many high profile heritage projects over the years. One we always enjoy returning to is this beautiful Surrey golf course.When it comes to replacing the windows and doors in historic buildings like this, Clement specialises in manufacturing new frames which provide a near match to the dimension and style of the existing ones. This ensures that none of the original character is lost and the new windows will bring advantages such as better thermal performance, increased daylight, less maintenance and improved security.The EB24 steel window range was specified as the right choice to replace the original fenestration at this over one hundred year old club house, due to its slim frames and much improved thermal efficiency when compared to the original windows.The client commented: “Clement Windows know what they are doing and deliver as they advertise. Having replaced nearly all our windows and doors within our historic clubhouse, I can fully recommend Clement. Timelines were met, costs were as agreed, and the aftercare service, when needed, was spot on. We have one last phase to complete, and we will again use Clement, a great partner for our needs.”

The India Buildings is located on Water Street in the centre of Liverpool’s financial and business district. It was designed by architects Arnold Thornely and Herbert J Rowse, following a competition to design an office block which was judged by the great Sir Giles Gilbert Scott and built between 1924 and 1932 for the Blue Funnel shipping line owned by Alfred Holt.The building’s design is influenced by the Italian Renaissance style and it has several features of the American Beaux-Arts style, including for example the sculptures of cherubs above the windows.Having sustained damage during World War II the building was restored to its original state after the war under the supervision of Rowse, the original architect.In 2017, the Grade II* Listed Building was purchased by Legal & General and it was announced that HMRC would base a regional centre there. Renovation works commenced with the focus on creating modern, comfortable office space while retaining the heritage features of the building.Clement Windows Group was selected to manufacture and install the new double glazed steel windows which match the original single glazed metal windows and improve thermal performance and energy use within the historic building. Almost 1,000 windows from the Clement MW40 range were specified, polyester powder painted in RAL 9016 (White).Alex Harrison of architects Falconer Chester Hall said: “We had the pleasure of working with Clement on the steel window replacements of the India Building refurbishment project. Their performance in every aspect of the work was outstanding, and we wholeheartedly endorse them for any future contracts of a similar nature. One specific area where Clement excelled during the early stages, was the support we received from them during our discussions with the city planners regarding the bespoke windows. Their contribution proved very useful in moving matters forward and the end result is exceptional.“

The Brewhouse, formerly known as Farsons Brewery was one of the first and finest examples of concrete-reinforced Art Deco buildings on the island of Malta. The building was founded and designed by Lewis V Farrugia and William Binnie and originally opened 73 years ago in June 1950.Now a Grade II listed building The Brewhouse has been part of a €86 million redevelopment project, reimagined by world-renowned London based ritchie*studio. Covering over 7,000 sq m of industrial space, the building now includes a unique mix of office, food and beverage, retail, visitor experience, and events space over seven floors.In a building of such historical and architectural significance the new windows not only had to look as close to the originals as possible, but also meet stringent requirements for thermal efficiency, as the building was designed to meet the strictest of environmental codes. Clement was thrilled that over one hundred white Clement EB24 steel framed windows were specified, featuring T bars and multi point locking.Robert Abela, the Prime Minister of Malta, was among around 400 people who attended the inauguration ceremony of Trident Park and The Brewhouse, one of the most iconic regeneration projects in Maltese history.ritchie*studio director, Ian Ritchie said: “Clement Windows provided the perfect steel window profile and workmanship solution to help restore this beautiful and iconic Maltese industrial Art Deco building."

Clement was thrilled to be asked to manufacture the new steel windows and doors for this spectacular Arts and Crafts style house in the Hampstead Garden Suburb. The new leaded Brooking windows and W20 steel doors, look just like the originals – perhaps even better! Hampstead handles were chosen for the windows and Kensington handles for the doors. They were all polyester powder painted in RAL 9005 Jet Black to match the frames. Our client is really pleased with the end result and said:“We placed a large order with Clement of double glazed leaded doors and windows. From start to finish we received a first-class service and the product quality and finish is superb.” 

It was a pleasure for all involved to work on this outstanding project, an original Arts and Crafts home which has been impeccably refurbished.The recent works included extending the house, as well as opening up and changing the layout. The interior has been modernised with a contemporary touch, but cleverly retains and enhances the home’s character. The interior design of the whole home is stunning. The bedrooms and bathrooms have been individually designed and are unique to their user. Mural wallpapers, vibrant pops of colour and striking, high quality fixtures and fittings help achieve this.A combination of leaded EB20 steel windows and W40 steel doors with genuine T bars were chosen to replace the external fenestration. The new windows and doors have slim, elegant frames but bring the benefit of improved thermal efficiency and security. Internally, a bespoke W20 door screen has been used to divide the kitchen and dining area.Both the client and architect are delighted with the outcome. Steven Harp from Harp and Harp said: “This project involved a delicate balance of modernising a home that had been barely touched in a century for 21st Century family life whilst trying to retain the beautiful Arts and Crafts character and charm of the original house. The new doors and windows by Clement were a perfect product to fulfil this brief, providing modern standards or thermal comfort with an aesthetic and quality that blended seamlessly with the elegance of the original metal windows that were still on the house.”The client said: “I was initially unsure about changing the fenestration and doors in our property, as they are such an important part of the building’s character, history and aesthetics. However, from our first meeting with Clement Windows, who were recommended by our building surveyor, I knew I needn’t have worried. They talked us through the different options in detail, provided extensive designs (and were always prepared to amend and refine these subject to our thoughts!) and also worked seamlessly with our architects to ensure that all we asked for was delivered and more. The finished product far exceeds any expectations that we had for windows and doors that matched our original steel windows and doors, now giving us the perfect look for the house with the added bonus of double glazing and additional safety and security. Their communication throughout has been excellent and we have felt looked after every step of the way. Installation was done ahead of schedule and the only issue we’ve had post installation has been dealt with efficiently and they have always had someone available to pick up the phone to us and come to site when needed. Really cannot recommend this wonderful company enough, for both their products and the overall experience. Thank you!”

City of London Freemens first opened in Brixton in 1854 for ‘the maintenance and the religious and virtuous education of orphans of Freemen of the City of London’. Paid for by the Corporation of London both boys and girls were enrolled from the outset making it one of the oldest co-educational independent schools.In 1926 the school moved to Ashtead Park in Surrey. The Grade II* listed Main House at Ashtead Park had been the home of Sir Robert Howard, Chancellor of the Exchequer during the 17th century.In 2016 an ambitious development project was commenced, due to span the next decade. The modernisation of the Main House, now the Sixth Form Centre, involved a redesign of the building and the new layout required fire screens to ensure the building met with current Building Regulations. Clement Windows Group supplied the internal fire rated doors and screens at the top of the adjacent internal stairs which are access controlled and linked into the main fire control of the building.

Hannah Cecil-Harden is a director at de Gournay, a family business which was founded by her father, Claud Cecil Gurney. De Gournay makes the most beautiful hand-painted wallpapers and fabrics and the company’s work is found in some of the finest buildings around the world. As you would expect, every room of Hannah’s London home has been exquisitely decorated. The property has undergone many transformations in the time that Hannah has lived there, but the most recent changes were needed to accommodate her expanding family. Hannah and her husband wanted their house to work better for life with their four young children.All the floors of the house have been updated, but perhaps the biggest change was turning the existing basement into a playroom with adjoining utility and bathroom. Having worked with Hannah and the team at de Gournay on a previous project, Clement was delighted to be asked to manufacture the new steel doors that were included within the designs. We were excited that the new steel doors were to be painted in unique vibrant colours to match the stunning wallpapers that adorn the new space and we worked closely with Hannah and her team to find just the right match. We always say that our bespoke steel products can be painted in specialist hues from across the entire colour spectrum – these doors demonstrate what is possible!Hannah said: “I thoroughly enjoyed working with Clement Windows on this exciting project which was for a children’s playroom. I wanted to go with bold and bright colours and they were so accommodating about this, everything about the project was handled professionally and with utmost care from conception down to a flawless install. It was an absolute pleasure to work on such a personal project with a business I have collaborated with before and I look forward to hopefully crossing paths again in the future!”

The existing commercial building at 22-23 Little Portland Street comprised ground, basement and four upper floors. Robson Warren Architects’ brief was to design a scheme that improved the office facilities and services, enabling the building to attract further tenants. Their proposals were required to take account of the environmental sustainability of the works and their impact on the property, which is situated in the East Marylebone Conservation Area.Peter Warren from Robson Warren Architects said: “The building was entirely of post-war construction, with single glazed, steel-framed, W20 type casement windows. The subdivision of the windows and slender steel glazing bars was a significant contributor to the appearance, but the existing single glazing would prevent the achievement of the required improvements in environmental performance. Refurbishment of the existing frames was rejected on the grounds that they were too badly corroded, not thermally broken and provided practically no insulation value, acting as a cold bridge and source of condensation.“Approval was sought from Westminster City Council to replace the existing windows with thermally broken, steel-framed, double glazed units to improve thermal and air tightness performance whilst replicating the existing appearance as closely as possible. Steel framing was chosen to allow the slenderest profile to be used while achieving the required performance improvements. Once planning permission was granted, proposals were sought from potential suppliers for both double and triple glazed windows and doors. After much consideration, slender Jansen Janisol cold rolled, mild steel sections which achieved the sight lines required were specified from Clement Windows. Their comprehensive system allowed us to incorporate open-in and open-out windows, French doors and lift and slide doors into the scheme.Clement provided clear drawings to assist in the development of the design which were approved for manufacture. A request for a bespoke RAL colour for the frames was accommodated. The installation was completed to our satisfaction without any significant issues. We would not hesitate to return to Clement Windows for enquiries about future steel-framed window projects.”

This delightful and spacious family home in West Sussex dates back to the early 1900s. When the current owner purchased the house it had old black framed steel windows which were single glazed and drafty.Clement was chosen to replace all of the original steel fenestration with new frames from their EB20 range. These were painted white to match the timber subframes, a fabulous choice as it really makes the house look stunning.The EB20 range comes with multi point locking to PAS 24 and allows for trickle vents to be included, if required, in the slim frames. The client said: “I used Clement to replace every window in my house (part of a full refurbishment). I found them very easy to deal with, not too long to wait for and very competitively priced. I’m delighted with the results, the windows look absolutely fantastic, fit perfectly and will hopefully last for many more decades! I’d highly recommend Clement.”

The owners of this four storey, semi-detached, Victorian home have totally transformed it to create a wonderful, contemporary space, full of character, colour and texture.The works undertaken included the demolition of the existing lower ground conservatory and the construction of a full width rear extension. The new space provides a large kitchen, dining and sitting area, but also retains the connection to the front snug. A two storey extension was formed along the side return, providing a boot room and utility space on the lower ground level and a cloakroom and WC on the upper ground level. A bespoke, black steel door screen from the Clement EB24 range was designed to form a glazed elevation facing onto the raised garden from the kitchen. The feature doors, along with other elements, such as the wide oak timber flooring, Bauwerk painted walls and a specialist kitchen provided by Daulby and Tickle, have created an incredible result.The Architect, Daniel Harris said “We’ve worked with Clement Windows on several residential projects, this one being the most complex. The process from initial sketch design through to installation was excellent. Clement produced highly detailed drawings and were very responsive throughout the development of the design. The installation team worked in close collaboration with the Contractor and ensured all elements of the openings were prepared and ready for installation. The end result was an extremely high quality and complex product installed with very low tolerances to an impeccable standard.”Photograph: GG Archard

The owners of this farmhouse in the Surrey countryside have sensitively restored it, transforming it into the stunning property you see today.Much consideration went into every aspect of the renovation, not least the replacement windows that were required to ensure the perfect finish for this Grade II listed home.Clement EB20 steel windows were specified as the right product to match the original fenestration, offering much improved thermal performance and security, with the benefit of multi-point locking. After much deliberation between the local planning department, the architect, contractor and the homeowners, it was decided that the new bespoke windows would feature an unusual flush T bar design and be painted Anthracite Grey, rather than keeping the original white frames and leaded glass. These clever design choices were a success and have transformed the look of this property.The homeowner said: “It was a delight to have Clement achieve excellence at our home in Surrey. Collaborating with the construction contractor, the quality of windows and execution was a testament to their commitment to deliver.”
