Clement Windows Group

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.”

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."

The new owner of this Pottery Studio in London wanted to make the most of the unusually shaped, original single door by changing the design so it included a double door instead. Thankfully this could be done without drastically changing the shape, as only some of the brickwork at ground level needed adjusting.Slim Clement W40 steel window profiles were used for the new double door screen. They are strong enough to be used for fenestration of this size and allow for the original T bar pattern which makes this such an interesting design. Thermally efficient, krypton filled double glazed units were used throughout. ‘Grey Aluminium’ was chosen for the polyester powder paint finish, which is a different colour to the original frame, but it works perfectly against the brickwork.The large door screen brings an abundance of natural light into the beautiful studio which features a vaulted ceiling.

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 Arts and Crafts home has recently been fitted with new steel windows from the Clement Brooking range and Clement W20 steel doors.As the property is located in the Hampstead Garden Suburb, a Conservation Area, it was imperative that the new bespoke windows and doors closely matched the look of the originals. The fenestration includes a mix of genuine T bars and beautiful Fenestra joints for both the windows and doors but also some charming leaded light windows.Clement has a wealth of experience working within the Suburb and for this project we knew the slim frames of our Brooking range, combined with our W20 doors, would work perfectly for the mix of styles found at this property.The leaded light windows had unique handle plates. We took templates of the existing ones to ensure that the new ones we crafted were very close to the originals.The client said: “"It was very easy working with Clement once we'd made the decision to renew our metal windows. They took great care over the smaller details such as the handle finishes, window hinges and the special decorative detail behind the top floor window pulls. As a result we have new up to date working windows that are fit for purpose, a pleasure to use and look at, and also comply with the Conservation Area and Listed Buildings requirements for this area."

The owners of this attractive, spacious home have recently refurbished and added a kitchen extension. Being situated within a London Conservation Area, it was vital that any new fenestration matched the existing. Clement was chosen to replace the doors and windows with new products from the Brooking and W20 ranges. All the new steel windows and doors are fitted with rectangular leaded lights - not only do they look fabulous, but they also allow a surprising amount of natural light into the house. The client chose dual colour for a number of the windows and French doors on the rear elevation. The outside frames were painted Pure White and the inside Black Grey - perfectly suiting the design and decoration.

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.”

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!”

In a small town just outside Stirling in Scotland is this beautiful, traditional property built from Scottish sandstone. The new owners have extended and completely refurbished the house, originally built in 1870. Although modernised and featuring some contemporary features the original charm has been kept.In order to maximize natural light, a total of 10 Clement Conservation Rooflights were installed. These not only look beautiful in the traditional Welsh slate roof but also improve thermal efficiency and are low maintenance.The homeowner said: “We are delighted with our Clement Conservation Rooflights. We have now fitted ten into our period house renovation and they look great.“Quality wise they are solid and well built, no problems with manual winders, and the double glazing, sound proofing and heat retention is brilliant. We searched around and Clement seemed a good price for the quality. Dealing with them as a company has been a pleasure, always helpful with sound advice and never a delay in delivery dates.“We have been lucky enough to work with very talented and courteous craftsmen and suppliers - like Clement, who went the extra mile to make sure that we fully understood the options available and helped us create the perfect home.”

Clement Windows Group supplied conservation rooflights for 1-5 St Paul’s Square in Birmingham. The historic Georgian building houses multiple office units and landmark venue - The Jam House. Opened in 1999 by Jools Holland and designer Neil Tibbat, the multi award winning venue offers live music and fine dining.Clement supplied 11 rooflights for the project, including the Clement 3, 4 and side hung ranges, all in a slate profile.Richard Clews MRICS from Jubb Clews Ltd, the architects working on the project, said:“1-5 St Paul’s Square is a Grade II Listed Building in Central Birmingham that was constructed in c1780 as town houses around a classic Georgian Square. The project included repairing the traditional slate roofs and lead-lined parapet gutters. Key design considerations included improving thermal performance and increasing the capacity of rainwater disposal to accommodate modern storm surges whilst remaining sympathetic to the traditional architectural details. The works were funded from the planned maintenance budget.Clement Conservation Rooflights were perfectly suited to this application. Several of the top hung windows were used for the upper floors whilst the side hung windows were used for the roof maintenance access.”

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.

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.”

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.”
