We really wanted to say thank you to everyone who has been involved in getting us this far. We have been really excited to see the structure go up and the on-site team have done an amazing job. The CLT looks great.

Mary & Klaus Morris | Blackwood House

I would like to record that I have been very impressed with your work on site and the efficiency of your construction team. The finished product is exactly as expected and was completed ahead of programme. Thank you for the efforts of your team.

David Spooner | Construction Project Manager | Hastings Pier Charity

Mayfield School are delighted with the new buildings. Innovative use of space and light in the atrium areas and other specialist classrooms will enhance the possibilities available to our staff and students.
The Sixth Form is designed not only to give a real feature (Heller-Up staircase), but is also a practical and useable large space which can be used by the whole school for various activities. The new building and external areas have created a real ‘WOW’ factor for our community as a whole.

Allison Greenwood | Deputy Headteacher | Mayfield School

The Mayfield School Project was delivered on time and within budget. It is to an excellent quality of workmanship which surpassed the expectations of the client team and the end user. The building’s design is rational, durable and above all maintainable which will ensure that Mayfield School will continue to provide teaching excellence within the London Borough of Redbridge.

Steve McConaghy | Senior Construction Project Manager| London Borough of Redbridge

I am the HT of a school in the UK which has been constructed using CLT. I am tremendously impressed with the very calm and purposeful learning environment that has been created. The students are so proud of the building and the exposed CLT is a major factor in this as it gives a high-end quality finish not common in schools in the UK. The CLT construction method enabled the building process to be rapid which was a major factor in us moving in on time.

Keir Smith | Head Teacher | William Perkin C of E School

We are completely delighted with the CLT!!! It’s been very exciting seeing our project in the factory and then going-up on site so quickly.
We love the exposed CLT walls and the character it gives the interiors – we can’t wait to move in. I think that the KLH team has been excellent throughout, from first contact, through the quotation stage to shop-drawings and the on-site erection crew – everyone has been very professional and helpful at all times. It has been a pleasure working with you all – I would be very happy to use KLH again in the future.

There is a great ambience in occupying a CLT school and it generates interest and a positive atmosphere with students, staff and visitors. Would definitely recommend it to another school.
