Contemporary Georgian Kitchen / dining extension

Looking to engage two designers to come up with ideas for a 50 sq meter extension on a 350 year old grade 2 listed building in northern England.

We have around 25 square metres of dead space, complicated by the fact that there is a staircase into a cellar creating a pinch point to put a small relaxed dining table at the end of the island unit.

We are looking for someone to design the space, with furniture, come up with a colour scheme for the walls, wall paper in old existing kitchen, ( which has minimal natural light , wall paper in the kitchen extension which is flooded with light due to the ambulance of glass used. Design and colour scheme of cushions to be made for the two large window seats, and other fixtures and fittings.

It is likely we will commission someone to make the furniture per the chosen design.

Probably much easier me sending WhatsApp video of the space, so you can see the space properly.

There is also a wine cellar to design. That currently is a blank canvas having not been tiled yet. The only existing cellar had a brick floor, so we will be putting down brick slips.
