Clement Windows Group

Our client is the owner of this superb 1930s house which is located in a suburb of Manchester. The property is currently being renovated throughout and as the old windows were no longer fit for purpose, the decision was taken to replace them with a product which looked just like the original windows, but offered a much improved specification.The Clement EB20 range of steel windows was chosen, with G+ bars and beautiful fenestra joints. The new windows are dual coloured - a dark bronze was chosen for the outside frames while white was selected for the inside to match the interior.

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.

Clement have replaced hundreds of industrial style steel windows at the newly restored Maple Building in Kentish Town, North West London. Dating back to the 1890s, the building has an interesting history. It was originally home to Maple & Co, furniture makers for the royal family. Then in the First World War sections of the factory were secretly modified to produce fighter plane components, canvas tents and other supplies for front line troops. More recently the building was used for office space until developers The Linton Group acquired it, turning an old converted warehouse into five floors of luxury apartments and penthouses.Interior architects, Gordon-Duff & Linton insisted upon a high specification throughout, focusing on strong acoustic and design performance. Clement W40 steel windows and Jansen double doors were the perfect choice, complementing the cosy, well-lit interiors that are a feature of the building, as well as offering superb quality and an impeccable match to the original fenestration.“The Maple Building is our flagship development. It has bags of industrial charm and period character due to its many original features. The steel windows by Clement respect and enhance these while simultaneously complementing the high specification modern interior design of the project.” said Gemma Gordon-Duff, Managing Director at Gordon-Duff & Linton.

Our clients had a traditional out-building in the grounds of their Grade 2 listed house. It was built in 1850, originally being used as a stable/coach house for the main property. Later it was turned into a garage and workshop, with an artist's studio built into the hay loft in 1970.Recently the owners decided it was time for change and realised the building had the potential to be a fantastic living space. An old metal window was in the original stable. This became the inspiration for the new steel windows and doors which would become a key part of the transformation.The renovation has been done sympathetically to keep the character of the building. Old bricks from the original walls have been restored. New lead work creates a feature around the upstairs dormer windows. Further additions to the building were completed in stone from the old garden, along with oak for outside walls. Our clients wanted to make the building environmentally friendly, so they installed a heat pump for underfloor heating and ensured comprehensive insulation of the whole building.The new fenestration chosen offers much improved thermal efficiency, security, and will be easy to maintain for many years to come. The sleek, elegant lines of the steel windows and doors look in keeping with the traditional feel of the property and bring in masses of natural light. The EB20 steel windows offer multi point locking and have been beautifully accessorised with Selbourne handles and matching peg stays.We are so pleased that the homeowners are delighted, they said: “Stunning windows and doors. Everyone who visits admires the windows - our builders are impressed too! We are so pleased we chose Clements. Your windows are the perfect fit and look magnificent, both complementing and enhancing the house inside and out, and marrying the building into our main house. From start to finish we have had excellent service. Thank you!”

Typical of most of the houses in the Hampstead Garden Suburb, the style of this beautiful home is influenced by the Arts & Crafts movement.The original steel windows and doors were draughty and no longer fit for purpose and so they needed replacing. The Clement range of Brooking windows, which feature a specialist ‘putty fronted’ system, was chosen together with doors from the Clement W20 range, to match the originals perfectly. The new, bespoke steel doors and windows were painted ‘Jet Black’ on the outside to replicate the previous fenestration and ‘Traffic White’ on the inside to complement the interior. The homeowner said:“I am absolutely delighted with Clement and would recommend them very highly. Their workmen were very professional and swift and they left the house tidy each day. They were a pleasure to have in the house whilst they were doing the work.”

The Harley Street Conservation Area (HSCA), designated in 1968, is rich in history and architectural significance. The area is known for its terraced houses from various periods, reflecting different architectural styles from Georgian through to 20th century Modernism. The HSCA is situated within the boundaries of the ancient Manor of St Marylebone, whose history can be traced back to the Domesday Book in the 11th century.Situated in this area is this fine, Georgian-fronted apartment building which has Art Deco-style fenestration. Its historical importance meant that when it was time for the existing windows and doors to be replaced, a lot had to be considered!Clement was chosen to manufacture and install the new fenestration in a number of the apartments here, because of our wealth of experience on similar projects and also because we offered the right product. Our bespoke EB24 range is a close match to the original windows but with a much improved specification. Dual colour was an option for the new windows, so for this particular apartment they were painted black on the outside and white on the inside to match the owner’s interior.

Clement was thrilled to manufacture new bespoke steel doors and windows for this magnificent Georgian-style home set in the South Downs in East Sussex. The house has been refurbished internally and externally and the existing loggia has been extended to house a new kitchen wing.Six arched head steel doors and window sets were incorporated into the design of the extension. These were manufactured by us from our W40 range of slim steel sections. They let in masses of light and provide a way through to the newly landscaped grounds, at the same time creating a stunning feature - the result is phenomenal.Clement also crafted a series of EB24 steel windows featuring Fenestra ‘T’ bars for the top floor of the house and the combination of different fenestration types works perfectly.The project won the House & Garden ‘House of the Year’ award in 2023.The Architects said: "We had a complex detail of Stone arches, steel frame, the Clement windows and doors and plasterwork internally, requiring a high level of precision. Clement helped co-ordinate the packages for a seamless integration."

As an Architectural Designer, Pauline Sutton always specifies Clement Conservation Rooflights for projects where rooflights are required.This country office in West Sussex is one of her latest developments. The brief was to convert a residential outbuilding to provide both a home-office and an art studio, all with minimal impact on the historic integrity of the C18th building.After carefully repairing the oak timbers in the roof; new felt, battens, insulation and re-used handmade clay tiles were added. Two Clement 0 rooflights were then fitted and dressed with bespoke lead work. The spaces were completed with two new oak doors, the stripping back of some old brick-work, lime-mortar repairs and new electrics.As the rooflights were slightly out of reach, brass pole winders were fitted and a winding crank is used to open and close the rooflights.Pauline said: “Here at Pauline Sutton Design we are happy to regularly specify Clement Conservation Rooflights within our Material Schedules and Planning Applications. Listed Building Consent applications here in The South Downs National Park especially require the top quality and carefully considered design by 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.”

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!”

Our client, One 17 Design, acted as Architects, Interior Designers and Project Managers for this superb project with involvement from inception through to completion. Their brief was to create a home office / garden room in the grounds of an existing detached home, which was done by extending the detached garage.The material palette for the garden room predominately featured oak and steel. Blackened oak cabinetry and steel fenestration provide a striking contrast against the natural oak frame and cladding. Clever detailing in the relationship between the oak frame and steel doors adds a contemporary twist. The bricks for the outside of the building were selected to match the brickwork of the existing bungalow. Bespoke Clement steel windows and doors from the W20 range were chosen for the project, including an interior door, fitted with reeded glass that leads to the bathroom. All handles were powder coated black to match the steel frames.The project won “Best amazing space” at the 2022 Northern Design Awards.Freddie Garside, Partner and Director at One 17 Design, said:“We and our client were delighted with the finished doors and screens. The narrow framed black steel doors complement the natural oak frame perfectly. Clement were very professional, efficient and responsive throughout the whole project.”Photography: Joe Cotterill

Kew Studios and Works is no ordinary workspace! Formerly a manor home, the building has been completely refurbished, but sympathetically to incorporate the original period charm in the new modern design.Sustainability has been key throughout: solar panels, a living green roof and electric vehicle charging have all been included and there is even a space for safely leaving bicycles. Already achieving a B Energy Performance Certificate (EPC), it is hoped the development will also gain a BREEAM Very Good certification.Clement was thrilled to manufacture and install the new steel windows and doors required for the project. We offered a number of products which suited the renovation perfectly. For the outside of the building, Clement’s W40 steel door and window profiles were chosen. Instead of being painted, these have been left with a Clement Naked Steel galvanised finish, which looks stylish and contemporary.Inside we used Jansen Janisol 2 and C4 profiles to create a series of internal doors and screens. These allow the ample natural light to flow through the space beautifully.Andrew Martin, Founder of AMD Interior Architecture said “The project brief was to create light, bright, welcoming spaces which are modern and functional but true to the original character of this former 18th century house and connected 1940’s warehouses. Clement’s steel-framed windows and doors help to achieve this, allowing masses of natural light to flow throughout the space. The service received from start to finish was outstanding, as was the result.”

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 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

Berwick Street is a lively and diverse community in the heart of London's Soho district, built between 1687 and 1703. It runs between Oxford Street to the north and Peter Street to the south and is well known for its thriving market which was established in the 18th century, making it one of the oldest markets in London. 90-104 Berwick Street has recently been transformed from an unattractive 1950s block into a stylish, contemporary, mixed use development. Although unlisted, the building is situated in the Core Central Activities Zone and the Soho Conservation Area, so it was vital that any changes made were in keeping with the surroundings. Clement Windows Group was requested to supply and install the custom- made steel windows and door screens used for the shop fronts on the ground level. A combination of products was specified from both hot rolled and cold formed steel profiles all with polyester powder paint surface coatings. These included Clement W40 steel windows which sit beside and above the doors, the Jansen Economy 50 range of single and double doors and Jansen Economy 60 range of bi fold doors.The Project Manager, Ben Styles said “The Clement W40 steel windows and the Jansen Economy doors provided us with the slender, elegant frames we wanted for this Central London development, giving the shop fronts a contemporary look while remaining true to the urban origins of the site. Clement delivered to our timescales, and we would use them again.”
