Margram were a land developer with an involvement in several service areas.
Mostly, Margram would purchase land next to a junction on a busy A-road, and kit it out with a restaurant (usually McDonald's), a petrol station and sometimes a motel.
When they purchased land next to motorways, their design policy was very similar. In order to meet the motorway service area requirements a large amenity building would be built, but it would be clearly divided into segments with a different door for each. The two they built were branded with McDonald's signs.
In 2003 the motorway sites were sold to Extra and other facilities were sold on.
The following services were owned by Margram:
- Blackburn with Darwen (M65)
- Bourne End (A41)
- Crossbush (A27)
- Cullompton (M5)
- Minster (A299)
- Tunbridge Wells (A21)
The following motorway service station was known to be planned by Margram but it was never built:
- Tetsworth (M40)
