Inwood is the company supplying the timber frame building and Sweet Chestnut cladding for the Rye Harbour Discovery Centre, under construction by Baxall

Emma Chaplin from Sussex Wildlife Trust speaks to Inwood Director Nigel Braden

Tell us a bit about Inwood

I set up the company in 1999. I employ 10-12 people here at our workshop at Whitesmith near Lewes, including my son Laurence (Production and On-site Manager – we’ve worked together for 15 years now), plus we use an on-site gang of specialist erectors for putting up the buildings.

Inwood is known for timber buildings, from the Scottish Parliament to the visitor centre at Winchester Cathedral. We’ve won The Wood Awards a number of times.

What’s your background?

I’ve run timber companies for thirty years and also an architecture practice.

What appealed to you about the Discovery Centre project?

I was interested in working with Sussex Wildlife Trust. Your work is really important.  I’m a member and I’ve got my own wildlife garden – including a Kestrel box I’ve had for twenty years, with new Kestrels reared each year. I support the idea of using locally-sourced, sustainable wood in Sweet Chestnut. Coppicing has a positive impact on the ecology of the woods we’ve taken it from (Maplehurst Wood near Hastings).

What qualities does Sweet Chestnut have?

It’s sustainable, it grows quickly and it’s naturally durable. By processing the way we do, ‘finger jointing’, we make it usable, because we end up with longer lengths with no defects. This is a process I developed to enable Sweet Chestnut to be used in construction. It has its own peculiarities. Tannin runs out, so a white render can become tea-coloured.

We are the only firm in the UK 'finger-jointing' Sweet Chestnut. This means making long timber lengths from small sections - resulting in long length boards for cladding and lamination. We also have a new specialist ['seven-axis CNC'] machine, which creates 'dovetail' housing joints for the panel construction. This makes it very strong and secure.

Give me some Discovery Centre stats

We’ve made, or are in the process of making, 53 internal panels, 30 external panels and 32 roof panels. There will be six lorry loads of processed wood travelling to Rye Harbour Nature Reserve.

Over the last two years, coppiced Sweet Chestnut has been cut, air dried and kiln finished (using biomass energy). It then went to a sawmill in the Midlands, before coming back here to be processed into cladding boards for the walls.

As of now (early August 2019), the specialist timber team is on-site at Rye Harbour, staying at the caravan park there, which is handy. We’re just finishing here at Whitesmith. Weather conditions permitting, there is three weeks' work building the structure at Rye Harbour, then three more weeks on the cladding. 

We’ve used about a quarter of coppiced Sweet Chestnut in a hundred acre wood.

What do you expect the biggest challenges with the Discovery Centre to be?

We are used to challenging sites. But mostly, the wind, and other climatic conditions. My team is very experienced and careful. And since everything is prefabricated, there’s a minimum amount of work that needs doing onsite.  

What will happen to the cladding over time?

It will go grey, but how fast depends on where it is – so in the case of Rye Harbour, very quickly, what with the sun, rain, wind and sand.
