Clement Windows Group

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!”

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.”

This family home is in a notable Conservation Area in Surrey. Over a number of phases Clement has worked with the owners to replace the original fenestration in the house and also provide new steel windows and double doors for the rear extension.Rectangular leaded steel windows in slim EB16 sections were the perfect match to replicate the original windows at the front of the house and most of those at the back, including two beautiful bay windows. The same frames were chosen for the conservatory, but clear glazing was fitted here. This not only lets in plenty of natural light, but the addition of the T bar detail on the double entrance doors means it looks perfectly in keeping with the Arts and Crafts design of this home.The owners said: “Replacing the original 100 year old leaded light windows was a huge decision. Our house is locally listed in a Conservation Area so aesthetics were very important. We wanted to retain the look of the house but also the feel and quality of the windows was important.We couldn’t have been more pleased with the outcome. Clement were extremely helpful and friendly throughout the design, build and installation of the windows, which was very quick in freezing January conditions.The house is quieter, warmer and altogether more comfortable. In fact, a recent energy survey showed that we are losing more heat through the uninsulated cavity walls than through the windows.”

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.”

When the new owners of this wonderfully restored home purchased it, they had quite a challenge on their hands. The house has a fascinating history and has been significantly altered over its incredibly long life.The original two up, two down core is Medieval and this was extended on both sides by the Georgian inhabitants in the 1820/30s. The extension involved raising the roof height to create space for servants in the attic, as well as wrapping the entire house in more fashionable brick and adding sash windows.In the last forty years or so the house had fallen into disrepair and was in need of urgent restoration. Our client, the new owner, has done a fabulous job of renovating the house. This included the removal of the existing ten rooflights which were installed without listed planning permission and were bulky and not in keeping with the property.We were thrilled Clement Conservation Rooflights were chosen as the ideal replacement.The client commented: “The Conservation Officer was keen for us to rectify the current roof, so permission was granted to replace the rooflights, removing three entirely in the process.We chose to go with Clement due to the combination of unobtrusiveness that made sure the history of the house wasn’t negatively impacted but also the sleekness of the all-black slim profile design which we felt gave a nod to a new modern lease of life.Now they are in place, they look like they’ve always been there and as if the roofline has had the best type of upgrade. The quality fits the craftsmanship of the original timber frame of the house, and we know they’ll last along with this house for many years to come.”

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.”

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.

Mary Weaver was the Houses Editor on Livingetc for over a decade so she knows a thing or two about design! We were delighted that she chose Clement to manufacture and install the new steel doors she required for her beautiful new home in Brighton.Mary now lives in a wonderful Regency Town House. The kitchen is located on the lower ground floor which is where the two new doors have been installed. They bring in lots of natural light and open out into the charming walled garden.Mary commented: “I love my new steel doors which make the room much lighter and warmer and encourage the indoor-outdoor link to the garden. Clement were a delight to work with and made everything easy and straightforward. The fitters were super efficient and left the place spotless.”

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.” 

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 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.”
