What our clients say


Collaboration & Expertise

I believe that the success of the Hailsham Primary school project was due in large part to Morgan Sindall’s choice of modular construction and their selection of Strief as their supplier. Strief’s professionalism and efficiency helped achieve a reduction in programme while their collaboration and expertise during the design and construction was exemplary.

I would certainly recommend Strief as supplier for Modular Construction projects.

Brilliant from Start to Finish

Streif were brilliant to work with from start to finish at Hailsham and performed exceptionally. They were willing and happy to get involved early on in the project and had significant input during the pre-construction period, assisting to ensure that the design was progressed in a way that was compatible with their modular system and were also open and honest in bringing forward VE options which assisted in ensuring the project was delivered within the clients budget.

On site they were proactive in their approach, taking on board Morgan Sindalls SHEQ requirements and developing new bespoke plant and equipment for use in their works during the construction phase demonstrating best practice for Health & Safety. This included a new bespoke lorry access system meaning their panels could be accessed safely on the back of the lorries without the need for harnesses and airbags. Also a bespoke edge protection system was developed eliminating the need to rely on harnesses and lanyards when installing their floor and roof cassettes.

On programme, they over achieved, completing the 2500m2, two storey school building in just 11 weeks, 6 weeks ahead of programme. This enabled the critical first phase of the school to be handed over 6 weeks early, resulting in the client being able to move straight into their new school at the beginning of term and not needing to move into temporary huts as was previously planned. The overall school was then completed an impressive 11 weeks ahead of schedule, with a large chunk of this time a result of Streif completing early, and their impressive modular system allowing follow on trades to work much more efficiently due to the high quality of the walls and rooms left by Streif.

I would highly recommend the use of the Streif and their system, and I very much hope and look forward to working with them again in the future.

Striving for Perfection

Streif, from a day to day point of view were exceptional. They appear to have a great work ethic and the enthusiasm they show for their work that is rarely seen. They all have an eye for detail and strive for perfection and don’t miss by very far.

They were willing to change the way they have worked in the past to use and learn from MS site systems to their advantage. Streif were willing to use more PPE than they have possibly before and went out of their way to procure the best PPE for the task in hand finding and using an innovative hard hat. They also helped in the design of a bespoke guard rail system specifically for the Hailsham Primary School project.

Their system of construction shows great promise. The entire project team were very impressed with the speed and efficiency of how the building was assembled with the levels of accuracy they achieved. Credit should also been given to the manufacturing staff working in the factory whose hard work facilitated the great site performance.

I look forward to working with them again and again Ben Davison

True Collaboration

Wouldham All Saints Primary School in Kent was procured as a single stage design and build contract at RIBA stage 3+ for Kent County Council. The STREIF proposal formed part of our winning submission, providing overall programme savings and assurance for quality and project completion dates, which were deemed critical for Client success. STREIF was chosen as our preferred solution due to the in-built value in their ‘mature’ timber offsite system; for example, benefiting from factory fitted external windows and doors, and the inclusion of building services routes and cut outs ready for follow-on trades.

From initial appointment, STREIF worked collaboratively throughout the design stage, initially providing VE options which simplified some of the unnecessarily complex arrangements, whilst maintaining the overall architectural concept design within cost parameters. STREIF engaged with the whole design team and utilised the BIM model to develop their timber design and production drawings, leading to a seamless approval process.

Site activities were well planned and executed with accuracy. Both product and installation was robust and consistently high quality with minimal on-site finishing, easily achieving the required performance criteria for fire compartments and acoustics. Even the 18.6metre long glulam beam for the sports hall weighing 3.5 tonnes was efficiently procured and shipped on a special transport from Germany; to be lifted into position by the waiting crane on the same day – true collaboration!

Showcase for Modern Methods of Construction

In my opinion the structural timber solution at Wouldham All Saints Primary School can be held up as a showcase for Modern Method of Construction and offsite manufacture. STREIF’s precision on site coupled with excellent quality from the factory enabled us to construct an excellent School, on programme and to budget. This closed panel system gives programme certainty and significantly reduces health and safety risks due to reducing the number of trades and personnel on site.

The completed timber building is energy efficient; it is well insulated and at of 1.96m3/m2/hr greatly exceeds the design air permeability criteria – this will provide benefits to the Client and School in the long term through reduced energy consumption, lower heating bills and reduced maintenance. An excellent product delivered in an exceptional way.

Beautifully Designed and Built

I first heard of STREIF several years ago when a friend who is a main contractor was using them to build some housing association flats. I was intrigued but didn’t think it was for me.... However, last year when my father and I were staring out at the estuary across an empty slab with no CLT supplier, no architect, no main contractor and a lot of money wasted on fees, the name came up again on the lips of our quantity surveyor who had worked with them before.

Several meeting later with Bill Treves and his team, a site visit to a house that was being built by STREIF further up the estuary, and a trip out to their factory in Germany and we were convinced. The contract was signed, a new architect appointed, decisions made and we were back in business again.

The result speaks for itself. The house has been designed and built beautifully with real attention to quality, like those fantastically chunky German patio doors and the bomb proof vaulted zinc roof. Even the floors upstairs are screeded and they are utterly solid with underfloor heating throughout. Everyone says the house has a lovely feel both inside and out, and my parents are delighted. In fact they are already thinking of their next STREIF house – something about shipping one out in containers to the Caribbean.

As for me, well I’ve now left London and moved into the annex with my wife and children, so I must like the house mustn’t I?! Thank you STREIF.

The School is Thrilled with its Brand New Building

The School is thrilled with its brand new building. The finish quality is absolutely amazing with top quality timber window frames and doors that demonstrate the attention to detail and high standards put into the build throughout.

As Headteacher I was rather concerned that we would fail to make expected deadlines and we would have great disruption over the move in. How wrong I was! The building was constructed at a fantastic rate with precision panels imported from Germany and assembled on site with amazing skill. The children enjoyed many opportunities to see the construction progress and especially to watch the rapid change from floor slab to school-shaped building in a few short weeks!

The size and complexity of the design weren’t compromised at all and we are now very proud owners of an architecturally impressive school with a hall and entrance that is the envy of all of our friends and neighbours! The school really needs to be seen to be believed! Thank you to all who made it possible.
