The Astral Sonic Technology workshop is based in the Unity Business Centre, in Leeds, UK, situated within 15 minutes' walking distance from Leeds city centre, and served by many bus routes from all areas of Leeds.

The full address is:

Astral Sonic Technology,

Unit 38,

Unity Business Centre,

26 Roundhay Road,


LS7 1AB.


Opening hours

Our opening hours are Monday – Friday, 9am – 5.30pm, though occasionally these times may vary.

Since Astral Sonic Technology is a busy workshop, all visits are strictly by appointment only – please ring or text to arrange a time.


The Unity Business Centre building is situated at the bottom of Roundhay Road, next to the Dulux Decorator Centre. The main Reception is located on Roundhay Road, but the best entrance to use is the loading bay entrance in the gated car park round the back of the building. Once you are in the car park, head for the dark grey roofed building carrying the sign “Unity One”. Proceed up the white-railed steps and press buzzer 38 on the wall panel to gain access.

If arriving by car, you will need to enter the trading estate via either Enfield Street or Manor Street, which will lead you to the Unity Business Centre gated car park. Limited space is available for loading and unloading for a few minutes, which is usually long enough for items to be brought into the workshop and booked in. The loading area is the hatched area in front of the railed steps leading up to the door buzzers. The car park is monitored so please ensure vehicles are not left parked for longer than a few minutes.

For longer visits, unlimited free parking is available in the street areas directly outside the gated car park, and on Roundhay Road.
