Peter Jawor, Construction Director, Arcadia Construction

We have single sourced our timber frames from Merronbrook for 8 years and have always found them to be professional, responsive and accountable.

Simon Claridge, Owner, High Barn Developments Ltd
We have been using Merronbrook to design and supply all our trussed rafters, etc for twenty-four years. These have been for new build flats and houses. In more recent years, we have also used their easi-joists® at first floor levels.

To stay with a single suppler that long speaks for itself. But would add that we have always found the staff friendly, helpful & knowledgeable.
