NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement golf simulator rooms in Chelsea SW3, under one contract. A basement runs £450 to £780 a sq ft, construction only. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Chelsea terraces are tall and narrow. A golf room wants width more than most rooms do. Under one house the plot often falls short. So the room may stretch towards the garden.

The borough allows one storey under no more than half the garden. That storey cannot be split in two later. So height is the first number we settle, before any other room is placed.

The swing needs about 3.0 m clear. We lower the slab where structure and rules allow. A screen wall takes the ball, with impact padding behind it. Acoustic lining runs around the whole room.

In Chelsea we built a new basement and a kitchen extension under one contract. It is not a golf room. It shows one team running structure, design and fit-out together. That same team would design, price and build the golf room.

How wide must a Chelsea golf simulator room be?

Makers advise about 4.6 m across.

Many terrace plots fall short of that at basement level.

We test your plan against the house before you commit.

Can a Chelsea golf simulator room sit under the garden?

Yes, within the borough’s CD11 limit.

No more than half the garden may go.

The garden left over must stay as one area.

What is the tee to screen distance in a Chelsea golf simulator room?

Trackman’s published guidance gives about 3 m.

We add space behind the tee for the swing.

The length of the room follows from that.

Will a Chelsea golf simulator room be heard in the house above?

Not if the room is built to be quiet.

Padding, a floated floor and a lined ceiling absorb the impact.

Ventilation is kept quiet too.
