The Corner Office

The Corner House is an attractive garden room/ office that is designed to fit easily into any size garden. If space is at a premium then our corner garden office could be just the answer. It’s 2.5m high, so it is planning friendly.

A  fully insulated all year round use garden room, built with treated timber, house grade double glazed windows and doors and high-quality door furniture. All internal electrics, installation & delivery are included in the price. There are no hidden costs.

We use the best quality materials and all our buildings are manufactured to order in our Workshops, here in Horam, East Sussex. Our professional installation team is efficient and tidy.

Why The NFF Picasso is a superior building:

✔ We use an EDPM rubber roof - not fibre glass, which is prone to cracking. EDPM allows for a better finish

✔ We use Celotex insulation boards - providing a higher insulation rating than Rock Wool, found in some competitors' buildings.

We pride ourselves on using the best materials available - in many cases better than our competitors.
