bambam,
You should inquire of your planning officer what they will accept in your area.
If your house is a protected structure or in an architectural conservation area you may be limited in what you can do.
Section 4 1 h of the Planning and Development Act is your friend, but only insofar as it may be interpreted by the planning office.
You may affect the value of your property by applying a painted finished to existing red brickwork - it isn't something you should do on the hop.
