Extend wifi to garden office

[SB315]

I recently had a garden office built but wifi from house is not strong enough to connect tv,  laptop or even phone.

Is a booster available to improve service? Main router is less than 10m from garden room.

@SB315 You would be advisable to cable up your G room back to the Sky hub, or try powerline between both if you are not speed dependant user.
