Teenagers are not hanging out in the park in the evenings anymore, and most parents are quietly relieved about that. But the alternative, having them take over the living room or disappear to a bedroom, is not much better. A garden games room gives them a proper space of their own, separate from the house, where they can have friends over without it consuming the rest of your home.

And it is not just for the kids. The same space works equally well as somewhere for adults to watch sport, play pool, have a drink with friends, or just disappear for an evening. We design and build bespoke garden games rooms and teenage dens across Surrey, Berkshire and Buckinghamshire, built to the same standard as every other My Retreat garden room.

Quick answer
A bespoke garden games room from My Retreat typically starts from around £15,000, depending on size and specification. Most customers choose a 3m × 3m or 3m × 4m footprint, which gives generous space for gaming, seating and a TV setup. See our full cost guide for a detailed breakdown by size and spec.

Why a Separate Space Makes All the Difference

The problem with teenagers taking over the living room is not really about the teenagers. It is about the lack of separation. When the gaming setup, the friends, the noise and the snacks all land in the main house, everyone ends up compromising. A garden room solves that completely.

The same logic applies to adults. A dedicated space for watching sport, playing games or having friends round without it affecting the rest of the household is something most homeowners appreciate far more than they expect to. Once it is there, it becomes one of the most used spaces on the property.

Built Around How You Actually Use It

A games room has different demands to an office or gym. The electrical layout, the wall reinforcement for screens, the acoustic insulation, the number of sockets. We design around your setup from the start rather than retrofitting later.

Reinforced TV wall mounts

Strengthened wall fixings for large screens, projector mounts, or multiple displays. Rated for weight rather than just the studs behind the plasterboard.

Plenty of sockets

Gaming consoles, TV, mini fridge, neon lights, sound system, arcade machines. We design the socket layout around your equipment list at the start, not as an afterthought.

Hidden cable management

Sockets positioned behind the TV, cable runs concealed in the walls. The room looks clean from day one rather than a tangle of leads across the floor.

Year-round insulation

Standard foam EPS insulation in walls, floor and roof gives the same thermal performance as Rockwool. The room is warm in winter and comfortable in summer without needing extra heating.

Air conditioning upgrade

Multiple people, multiple screens and a closed door generate real heat. Air conditioning is available as an upgrade and is a popular choice on games room builds for exactly this reason.

Recessed spotlights

Standard recessed LED spotlights throughout. Position and circuit layout can be tailored for gaming setups where you want lower ambient light without losing task lighting entirely.

What to Think About Before You Build

A games room or teenage den is one of the more straightforward builds we do. A few decisions at the planning stage make a significant difference to how the finished space works day to day.

Size

A 3m x 3m room is a comfortable single-use games space. If you want a pool table, a sofa area and a gaming setup in the same room, 4m x 4m or larger gives you the space to do it properly. We design around how the room will actually be used rather than a minimum footprint.

Equipment list

Tell us what is going in the room at the design stage. The socket layout, wall reinforcement positions, cable runs and consumer unit sizing are all determined by what you are putting in the space. Adding a projector screen, an arcade machine or a mini fridge after the fact is much harder than designing for them from the start.

Power requirements

Most games room setups run comfortably on a standard 32 amp supply. If you are running a lot of equipment simultaneously, or something with a high draw like a large projector or dedicated server, let us know at the design stage and we will size the supply accordingly.

Connectivity

Online gaming needs a reliable, low-latency connection. A direct ethernet run from the house is the most reliable option and worth planning at the build stage. We can advise on the routing and whether a powerline adapter or external access point is more practical for your garden layout.

Planning permission

Most garden games rooms fall within permitted development rights and do not require planning permission. Whether that applies to your property depends on factors specific to your home, including whether your permitted development rights are intact, whether you are in a conservation area, and how much of your garden is already built on. It is the responsibility of the customer to confirm their planning position before proceeding. If you need help with this, we have an architect available as an additional service who can check on your behalf. Read our full planning guide for more detail.

Frequently Asked Questions

How much does a garden games room cost?
A bespoke garden games room from My Retreat typically starts from around £15,000 fully fitted, depending on size and specification. This includes foundations, full insulation, electrics, double glazing and installation. Upgrades such as air conditioning, reinforced flooring or additional socket runs will sit higher. See our full cost guide for a detailed breakdown by size and spec.
Do I need planning permission for a garden games room in Surrey?
Most garden games rooms fall within permitted development rights and do not require planning permission. Whether this applies to your property depends on factors specific to your home, such as whether your permitted development rights are intact, whether you are in a conservation area, and how much of your garden is already built on. It is the customer's responsibility to confirm their planning position before proceeding. If you need help, we have an architect available as an additional service. Read our full planning guide here.
Can the room be used for both teenagers and adults?
Yes, and most of our customers use theirs exactly that way. The space works for a teenage gaming and social setup during the week and doubles as somewhere for adults to watch sport or have friends round at the weekend. Designing the layout and socket positions to accommodate both uses from the start is straightforward and costs nothing extra.
Is a garden games room usable all year round?
Yes. Every My Retreat garden room is fully insulated using foam EPS insulation in the walls, floor and roof, which has the same thermal performance as Rockwool. With a standard heater or the optional air conditioning upgrade, the room is comfortable throughout the year. Multiple people and multiple screens also generate meaningful heat, which helps in winter.
Can I put a pool table or arcade machine in a garden room?
Yes. A full-size pool table needs a room of at least 4m x 5m to allow comfortable cueing clearance on all sides. Arcade machines and other large equipment are straightforward to accommodate. Tell us what you are planning to put in the room and we design the layout around it, including reinforced wall fixings and dedicated socket positions.
How do I get a reliable internet connection to the garden room?
A direct ethernet cable run from the house router to the garden room is the most reliable option for gaming. This can be buried underground or run along a fence line and is best planned at the build stage. Alternatives include a powerline adapter through the mains supply or a dedicated wireless access point mounted on the exterior of the house, both of which we can advise on.
How long does it take to build a garden games room?
The build itself typically takes 3 to 5 days on site. Lead time from order to installation is usually 8 to 12 weeks depending on our current schedule and the complexity of your build. We give you a confirmed installation date when you place your order.
Does a garden games room add value to my home?
A well-built, fully insulated garden room typically adds between 5% and 15% to a property's value. A dedicated games room or entertainment space is an increasingly popular feature in the Surrey market, particularly for families with teenagers or buyers who work from home and value having a genuinely flexible additional space.
