You will to decide on your weight capacity and number of axles. If you're
taking 8'x4' sheets, you will probably want brakes. Not only are they
required for 750kg (which is quickly reached transporting rubble or
plasterboard), but they are very useful for ground handling. If your car
isn't huge, you might even need brakes below 750kg.

Your design will need to take account of the restriction implied by the weight
of the towing vehicle. IIRC the maximum weight of trailer and load must not
exceed the weight of the car. So the heavier you make the trailer -extra
wheels, brakes etc, the more you reduce the load that can be carried.

In actual fact there is no legal limit on the weight a private car can
tow. See:-

If you have a light car you may be better off with the lightest unbraked trailer
design you can get.

In reality that of course may well be true.
