Afternoon,
I've had a busy day trying to look at ideal functional diagrams.
The following picture is a rough diagram which it is early development of my functional diagrams. I intend to develop this by using numbers to label the areas which are of interest and the important of the relation to the surrounding facilities.

This ideal functional diagram show, in a non contextual sense, how parks could be arrange to provide facilities for all visitors.

1.       The Car park should be situated close to the visitors centre and toilet; this means that visitors to the park have a good sense of place on arrival. This walk from the car park should have clear signage to help the visitors navigate their way to the visitor centre.  The car park should be clearly sign posted and provide safe access into the park.

2.       The visitors centre should be the start and end of the circle walks; this gives the park the opportunity to publicize the parks facility, attractions, food, refreshment and gift areas.

3.       All the toilets around the park should provide facilities for all uses. On the series of walks around the park it is important to make sure that there are toilets in easy access to the surrounding walks. 

4.       The visitors centre is overlooking the children’s play area, the location of these two areas is important. As children’s play area being located close to the visitors centre and the toilets means that all facilities are easily accessible if needed. With the children’s play area being close to the car park it means all visitors who have only come to use the children’s play area don’t need to travel across the whole park.

5.       The first short walk which will take around 15 to 20 minutes will give the chance for families with small children a change to adventure out of the children’s play area and the visitors centre.

6.       The second walk which starts and ends at the visitors centre as all the walks do should be designed to take 30 to 40 minutes. This walk should explore more of the park and its onsite facilities. As this walk is designed to take longer a toilets block and information point had been situated half way round to provide facilities for the walkers.

7.  The next two walks are designed to give visitors a more extensive view and challenging access to the park. (8) shows a 50 to 60 minute version of the 60 to 80 walk  at (9), they both offer changes in gradient and path material to challenge the users.  The paths have greater distances between toilet facilities and could be access from the local area rather than then visitors centre. The paths should be clearly sign posted to prevent users from getting lost.
