Most house extensions, though not all, involve getting Planning Permission. The rules for when Planning Permission is required are complicated. However, check this for general guide.

isabel barros architects will provide general advice on the need to obtain Planning Permission, comply with Building Regulations, etc. Following this we will carry out a dimensional survey of the floor(s) to be extended and study your demands in terms of your requirements.

We will then develop a design proposal that will suit your demands, this we call it concept design or sketch design because ideas are not completely mature or fully decided at this stage.

Once you are happy with our proposal isabel barros architects will produce the plans and particulars that are necessary to enable the planning authority to make a decision.


The Extensions SPACE MAKER Package includes:

  • Initial appraisal and survey of the existing interior and/or exterior, where appropriate.
  • Develop concept design from client’s brief.
