Office refurbishments

The new office is coming along nicely. Eight-foot-plus-high wall-to-wall shelving, made to measure, all now painted and largely filled; new desktop machine which arrive 7pm last night, plus backup hardware; ergonomic chairs...Next steps are are a new, large office table and, I think, a large comfy sofa, the latter to promote thinking time. Having all the books visible is a definite plus (see Don Norman's book Things That Make Us Smart).

But do I put the sofa next to the four large sash windows overlooking multifarious trees and wildlife (what *is* that extraordinary bird?) and move the desks onto a boring wall (near the whiteboards), so better to concentrate on work? Or keep the two desks with computers next to the windows overlooking the birds, bees and weather sweeping in across London? Decisions, decisions...
