How beautiful are these natural insulations, installed at our Suffolk barn conversion? The difference between a site full of these materials, rather than rigid foam insulation, is significant even before they are installed - there's a warmth and tactility, and a good smell!

This timber framed extension in Suffolk provided a new accessible bedroom to a cottage in the curtilage of a listed building, with a focus on connections to the garden. Sliding doors lead to the terrace, with meandering ramped paths through the planting ensuring that the beautiful outdoor space can be enjoyed by everyone. The client's own sculptures are nestled amongst the greenery.

On site in Suffolk - the conversion of an existing barn in the curtilage of a Grade II Listed house, being carried out by . Following repairs to the historic timber frame, a new oak structural frame has been installed to support the new mezzanine floor, including concealed joist hangers for the new joists. The window openings have been formed and surveyed by .co.uk for new triple glazed windows. These sit outside the historic timber frame and have been carefully positioned to work around the key timbers.

Insulation will be added to the walls, using a combination of blown h**p insulation between the frame and woodfibre boards over the outside face. Above, the refurbished roof will also have Pavaflex woodfibre insulation fitted between the rafters, with woodfibre boards below. These natural, sustainable insulations will provide a significant improvement in the thermal performance of the building.

Bespoke replacement staircase and landing at our C**t House refurbishment. The previously dark and disjointed circulation space has been opened up and now benefits from natural light across both floors. The original parquet floor was refurbished as part of the works, with new areas infilled to match. Main works and joinery by James Norman with staircase metalwork fabricated by N&A Engineering; design by us.⁠
