Feasibility Studies:

You may be unsure of the most practical way to improve your home, whether to add an extension or to convert your roof space for instance, or to remodel the interior.


Indeed, some domestic extension proposals may fall within Permitted Development criteria (PD) i.e. not requiring a submission for Planning Permission.

The Welsh Assembly Government (WAG) have published Permitted Development Supplementary Advice for Householders, which you can find for yourself on the WAG website by using the link on the right. This document provides clear general advice as to what you may be able to achieve.


However, even if your project qualifies within PD, you may be required to submit a Prior Notice Application to your local Planning Authority.


By conducting a Feasibility Study for you, we can fully investigate all options before submitting a Prior Notice Application or preparing any detailed design drawings for formal Local Authority approvals (i.e. Planning Permission and / or Building Regulations).


Our fees for such studies are based upon our very reasonable hourly charge and we'll advise you fully during a Free Initial Consultation.


We can also prepare and submit a Pre-Application Planning Enquiry to your local Planning Authority on for you (see opposite).


Again, before we start any work, we'll provide you with a written fee estimate.

Pre-Application Advice:

Where there may be uncertainty as to the planning requirements for a particular development project within Pembrokeshire, the Planning Departments of both Pembrokeshire County Council and Pembrokeshire Coast National Park Authority operate systems that facilitate initial appraisal and advice prior to making formal outline or detailed planning applications.


Both Pembrokeshire County Council (PCC) and Pembrokeshire Coast National Park Authority (PCNPA) offer you, as a householder, the opportunity to speak with a Planning Officer at their respective offices. The PCC Planning Department invite you to visit Main Reception at County Hall in Haverfordwest any weekday between 9am and 4pm and ask to speak with the Duty Officer. The PCNPA offer the chance to visit their Llanion Park, Pembroke Dock offices to speak with their Duty Officer on Thursdays only, strictly by appointment. In either case the Duty Officer will voice their opinion, but may suggest that you might submit a formal Pre-Application Planning Enquiry in order to obtain a more detailed written appraisal.


Submission of a Pre-Application Planning Enquiry can be an invaluable initial approach for many development schemes. But please note that both of the Pembrokeshire Planning Authorities are now making a nominal charge for this service.


For compiling the appropriate information and submitting a Pre-Application Planning Enquiry on your behalf, sometimes including a preliminary Design & Access Statement (DAS) - particularly for a new-build, we make a modest charge.


During a Free Initial Consultation, we'll explain the process for seeking pre-application advice and provide you with our written Fee Estimate, including details of the charge you will have to pay to your Planning Authority..
