Kingsholme designs and builds bespoke timber orangeries and conservatories for homes in Radlett and the surrounding area. Whether you want to extend your kitchen, create a dining space or add a separate garden-facing room, we develop the design around your property and how you want to live in it.
Our timber windows, doors, roof lanterns and decorative joinery are manufactured at our workshop in Studham, Bedfordshire. We can coordinate a complete design and build service or manufacture and install the specialist timber structure alongside your architect and builder.

We develop the layout, proportions and architectural
details around your property. Detailed 3D drawings help
you explore the design before manufacture begins.
Our timber windows, doors, roof lanterns and decorative
joinery are made to order at our Bedfordshire workshop,
giving us close control over materials, detailing and finish.
We can coordinate a complete orangery build or provide
specialist manufacture and installation alongside your
architect or builder, with a clearly agreed scope.
An orangery should complement the house from both inside and outside. Window heights, roof proportions, brickwork and painted joinery all influence how naturally the extension connects with the original building.
Traditional glazing bars and decorative mouldings can reflect existing architectural features. Simpler detailing and larger panes offer a different approach where open views and a contemporary appearance are priorities.
We develop these choices together, considering the extension from the garden and through adjoining rooms. The result is a design that responds to the house as a whole.
A well-planned extension starts with how the room will be used. A kitchen island, dining table and seating area each need sufficient space, with clear routes between the house and garden.
We consider furniture and cabinetry before finalising windows, doors and the roof lantern. Solid wall areas can provide useful storage space, while the arrangement of glazing influences daylight and views.
The connection to existing rooms is equally important. Structural openings, floor levels, heating, ventilation and shading are considered alongside the appearance of the new space.
Kingsholme has specialised in orangeries, conservatories and roof lanterns since 1997. Our service brings together design development, timber manufacture and the practical requirements of installation.
For a complete build, we can coordinate necessary approvals, foundations, construction, structural alterations and agreed finishing work. The scope is established around your property and the extent of the project.
If your architect or main contractor is managing a wider renovation, we can manufacture and install the specialist timber elements. Agreeing dimensions, connections and responsibilities early helps the workshop and site teams work to the same plan.
A bespoke timber roof lantern introduces daylight from above and can give an extension a distinctive ceiling feature. Its proportions and position should relate to the space below, whether that is a kitchen, dining room or sitting area.
Our traditional roof lanterns are made to order, with glazing arrangements, joinery details and painted finishes chosen to suit the project. They can form part of a complete Kingsholme orangery or be installed within an extension constructed by your builder.
We coordinate roof opening and supporting upstand requirements with the project team before manufacture.

The initial contact with Kingsholme and the professionalism of the product presentation singled Kingsholme out above other companies considered.
In short, we unreservedly recommend Kingsholme Conservatories as a highly competent company, offering excellent service and value for money, with whom it has been a pleasure to deal.
Colin has helped us throughout the process, and we were very pleased when he suggested another house in Harpenden that we could visit to see the quality of work before placing an order. We also thought your workmen on site were efficient, polite and customer focused.
We appreciated the low-key sales approach, and particularly valued the maturity and attitude of the people who worked on the conservatory.
The workmen were a pleasure to have, always polite and helpful. Mark, your no-pressure sales approach was a welcome change from the so called bigger companies.
My conservatory is much admired by all who see it and they comment on the high quality of the result. For me it is a daily joy. My thanks to you and I shall certainly recommend your company.
Now that the conservatory is finished Sarah and I would like to express our appreciation of the work that has been done. Back in the summer when we decided we would like to build, we had no idea who to go to and no local friends to make recommendations. We looked on the internet using words such as “bespoke, quality and individual” By chance we came across Kingsholme and then of course met with you.
We said that we did not wish to be involved with any sub contractors but that the entire job should be project managed by you. We also made it clear that we wanted a firm price for the job which would not change unless we altered the brief. You delivered on both counts.
From day one of the ground works until the final finishing touches were made recently all the people representing Kingsholme have been excellent. Skilled tidy workers, always polite and a pleasure to have around. Whilst the job was not always straightforward, i.e. the guttering which had to be specially made, there was no question of you cutting corners or compromising your quality standards.
We are delighted with the final result and especially pleased that we selected your company. Many thanks to all the team and particularly you Mark.
The whole process from our initial meeting with you through to works on site through to completion was undertaken in an extremely professional manner, resulting in an excellent conservatory design, a standard of work that is first class and undertaken by friendly/helpful operatives. The attention to detail was evident at all times.
The co-ordination of the different work disciplines was particularly impressive with the general disruption during construction kept to an absolute minimum and the site being kept clean and tidy throughout the course of the works.
Michelle and I wish to express our appreciation for the service provided by you/your company and cannot recommend you highly enough.
The whole experience from start to finish was very pleasant and professional. There was no pressure or haggling on prices, this was in total contrast to other prospective suppliers. Mark gave us some excellent design suggestions. The overall quality of workmanship was also first rate.
We have been very happy with the service provided, please keep up the good work!
Very pleased with general workmanship and helpful construction staff. Would be pleased to recommend your company to other people. Greatly appreciated Mark’s design of conservatory, blends in well with rear of house.
Thank you for making it a relatively easy experience for us! As mentioned to you previously, we are very pleased with the results.
We are really pleased with the conservatory and we will certainly recommend you.
We are very pleased with the final product, which looks excellent. Mark’s approach throughout was honest and helpful, in direct contrast to the many other sales people from other companies who were clearly only interested in securing the sale.
The fantastic reviews I see here reflect the experience we have had with Kingsholme. It has been faultless from the first contact through to completion of our orangery. The technical information on the website gave me confidence that the product is outstanding, based on years of experience. All of the team were outstanding, highly experienced tradesmen. The final product is of the highest quality in terms of design, materials and construction. There was absolutely no ‘sales’ involved and during my first call, I was given a ballpark figure based on the size of the space; the final cost was only higher because we increased the size and there were no hidden surprises. The first design we received was exactly what we wanted (they ‘got it’) and the only tweak we made was around the size of a side window. Mark agreed to take on some additional work inside the house, opening up a supporting wall between our kitchen and old dining room. I had struggled to get anyone to take this on, so was grateful to him for doing it. This proved to be quite a challenge for the team based on how the original wall was constructed and took a few more days than expected, however they worked constantly in horrible conditions until it was done. We didn’t have a lot of time to get involved in the project and that wasn’t an issue in the end as everything was taken care for us. It’s rare to say this of a company – we have not had a single issue with Kingsholme. Thank you to everyone involved.
We would wholeheartedly recommend this company. Every member of the team were polite and helpful, from our initial site meeting through to completion of the project. We feel that they offered a very high standard of work at a fair price. The design is top end and certainly comparable with the companies that advertise in House and Garden Magazine and buildings that we have seen exhibited at The RHS Chelsea Flower Show. From the groundwork team through to the decorator, every member of the team were highly experienced and meticulous with every detail of the work that they did to create a stunning orangery for us.
I would like to take the opportunity to thank you for all your help, assistance and understanding. It has been a pleasure dealing with you and we are delighted with the end result. If you wish to use us as a reference we would be more than happy to recommend you/ Kingsholme to prospective clients.
Excellent throughout; friendly, courteous employees. Good to your word regarding all aspects of the build.
Thanks for a good job – we are very happy with the end result.
I’m very happy with the quality of work and materials, the finished conservatory is exactly what I wanted. I would be happy to recommend Kingsholme or provide a reference site.
All the workmen were helpful, efficient and trustworthy. The standard of work was excellent and we are very satisfied with the end result. We would have no hesitation in recommending your firm to friends and neighbours.
The attitude of everyone connected with the selling and building of the conservatory was very good, both to their jobs and to the customer. I would recommend Kingsholme to anyone I knew who were considering having a conservatory.
Many thanks for the support and advice during the problems with the neighbours and development company. I appreciated very much the care and effort given during my major stress-out times! Your calm and matter of fact approach was very reassuring.
I am very pleased with the result, thank you.
We are delighted with our orangery, thank you for all your hard work.

We are very pleased with the conservatory and will have no hesitation in recommending you to all who admire it.
We have already recommended you to two other people, both of whom are having conservatories built by you. All the workmen were pleasant and polite, and got on well with the job. We are really pleased with the end result, and would have no hesitation in recommending you to anymore of our friends who are thinking of having a conservatory.
We are very pleased with our conservatory and patio, and would recommend Kingsholme to others

Overall the work was done to a very professional standard, particularly groundworks, foundations and finish (plastering, flooring, electrics and heating) Care was taken to keep things tidy and to clean up afterwards. Very satisfactory!
The conservatory is looking really good. A great bunch of guys on site who got on with the job and kept things tidy. Very happy with the result and would recommend Kingsholme.
We are enjoying our new orangery enormously. We absolutely love it and so does everyone who visits. We spend a huge amount of time in here and it has added so much to our enjoyment of the house. People keep commenting on how well the design sits with the rest of the property — it looks as though it has always been part of the house. Thank you to Mark and the whole team for an excellent job. We would definitely recommend Kingsholme.
We are delighted with the finished project. The team were professional throughout and the quality of the work is first-class. We can’t wait to make full use of it now the weather is improving. Would recommend Kingsholme to anyone considering similar work — and we’re happy for prospective clients to come and see it if that helps.
Mark and the team delivered a great-looking space for us. It has transformed the way we use the house and looks exactly as we hoped. Straightforward to deal with and the finished result is excellent.
I was very pleased with the whole process, from the first phone call right through to completion. Clear communication, no surprises, and a professional finish. Kingsholme made what could have been a stressful job straightforward. Happy to recommend them.
Really pleased with the work Kingsholme carried out on our orangery and new opening. The team were careful, considerate and left the place tidy. Very little extra making-good was needed, which says a lot about the quality of the installation. Grateful to Mark and everyone involved — we would use them again without hesitation.
