ᐅ Slope and Site Access Planning

Created on: 2 Oct 2020 12:22

Hello Homebuilding Forum,

We are more or less about to start the project, and finally, the surveyor has sent the data to our architect.
Now we have a problem with the reference height: our building plot starts 7m (23 feet) from the property boundary, and according to the architect, the bottom edge of our garage is at about 4m (13 feet) elevation. This makes it impossible to create a reasonable driveway directly into the garage, as the slope would be around 50%.

Do you have any suggestions on how to keep this within a sensible range without having to create switchbacks for the garage entrance?

I have attached the architect’s drawings.

Thank you very much and best regards, Anson

And if I understand the original poster correctly, the general contractor (GC) doesn’t want to start deeper because, as a timber construction GC, he only wants to subcontract the basement and not the first residential floor above.

The GC will have to accept that if he wants the contract. For projects like this, separate contracts are apparently much more flexible.

I’m afraid the original poster tends to favour inclusive planning by the general contractor. However, I don’t see anything resembling a standard building plot here :-(

We have a slope of 1.2 m (4 feet) over 8 m (26 feet) in length, slightly steeper than in Hampshire. My parents have a section with 2 m (7 feet) over 6 m (20 feet) length. Without ice and snow, it’s manageable. However, in winter, you often end up sitting on your backside unintentionally.

Regardless of what the structural engineer says, the parts in contact with the ground must be made of concrete.

Be sure to plan the outdoor area as well: stairs, terraces, retaining walls.

clearly shows an integrated garage on the uphill side as well

Whether the garage is fully integrated cannot be determined with certainty due to the missing third dimension, since a system section cannot be assumed to be a typical true straight section. In any case, the garage is located below the basement level and does not extend the full depth of the house.

Floor plan: two orange rectangles 'Ga' and 'Whs' in the space; blue lines, street at the bottom.

Here is an example of an underground garage with visitor parking spaces in front.

@Escroda:
Thank you very much for your suggestion. I do know that we need to do earthworks, but I have no interest in reshaping almost the entire plot.

At the moment, we are still puzzled about how to implement everything in a way that is feasible and, above all, affordable.

Best regards, Anson

Statements addressing questions such as the relationship between the concrete contractor and the timber builder, as well as your connection to the employer of the draftsman, would be very helpful—in fact, ideally free of charge. We would then be happy to contribute to solving the puzzles.
