Basement golf simulator rooms in Marylebone.
Golf simulator room · a private basement golf room, as we would design itVisualisation
A golf room wants width and height that a Marylebone terrace rarely has. A mews or whole house can work.
Will a golf room fit under Marylebone?
- About 4.6 m
- Room width makers advise for a full swing
- About 3.0 m
- Clear height makers advise, 2.85 m at least
- Policy 50
- Only one storey to find that height
NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle basement golf simulator rooms in Marylebone W1, under one contract. A new basement dig typically runs £500k to £900k. Converting an existing basement runs £180k to £300k. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Honestly, often not under a narrow terrace. Many Marylebone houses are a single room wide. A full swing wants about 4.6 m across. Where the house is narrower, a putting and short game room may suit better.
Height is the second test. Makers advise about 3.0 m clear, and 2.85 m at least. Policy 50 gives one storey under the lowest original floor. So the slab level is settled before anything else.
A wide mews, or a whole house on a deep plot, changes the answer. The room can then stretch under part of the garden. No more than half the garden may be dug. A metre of soil goes back on top.
We have not built a golf room in Marylebone. We renovated a listed apartment here, and built lower floors in Chelsea. One team would design, price and build it.

Is a Marylebone terrace wide enough for a golf simulator?
Often not for a full swing, which wants about 4.6 m.
A putting and short game room may suit a narrow house.
How much height does a Marylebone golf room need?
About 3.0 m clear, and 2.85 m at the very least.
We set the slab level first, inside Policy 50’s one storey.
Can a Marylebone golf room run under the garden?
Yes, under no more than half of it.
A metre of soil and a drainage layer go back on top.
Can a Marylebone mews house hold a golf simulator?
A wider mews can, if access allows the dig.
We test the width and the spoil route before design.
