How much does a home cinema room cost?

Question

We've got a large basement room we want to convert into a proper home cinema. What's a realistic budget for the fit-out, including soundproofing, screen and seating?

Blerim · Answer

A dedicated home cinema in a large basement typically costs between £20,000 and £60,000, depending on the level of finish and equipment chosen. This would usually include soundproofing, acoustic treatment, screen or projector, surround sound system, seating, lighting and decoration. Premium installations with bespoke joinery, luxury seating and high-end audio/visual equipment can exceed £100,000. The best approach is to set a budget and design the room around your priorities.

You will need to budget for between £18,000 and £25,000 depending on the some of the room and finishes .

Fairly difficult to be precise as there are many variations of technology and furniture on the market. I would say a realistic budget of £4/5 k would get you a nice facility. 
If you have a budget in mind rooms can be designed around that also. Site visit required to comment more accurately

Dragos Daniel · Answer

The cost depends on the room size and the level of specification. As a guide, a good-quality home cinema conversion typically costs £10,000–£30,000, including soundproofing, electrical work, lighting, decoration and seating. A high-end installation with premium audio, projector, acoustic treatment and bespoke seating can exceed £50,000. As your room is already a basement, a site visit will help assess any additional work required, such as ventilation or damp-proofing, before providing an accurate quotation.
