We are just about to start planning to build our new home. This will be a 4 bedroom dormer style house as per council stipulation...

Before we go in deep with an architect wondered if there is much difference in build costs based on 2 designs, brick and block (potentially half rendered) with slate/tile roof.

We are all new to this and potentially trying to save costs where we can, building a 200-250sqm property with a bit of kerb appeal, no garage.

1) L shape - straight front and sides with additional section at back for a long lounge

2) L shape as above but with centre front petruding for a porch, storage and WC downstairs and larger bedroom upstairs.

Both with a usable loft just for storage.

I'm aware no 2 is more work but would it affect the cost drastically, I've always preferred a second set of door opposed to door straight into hall.

Any ideas, advice or opinions welcome. Thank you.
