The Process

Considering a loft conversion can seem scary. Find out a little more about the process here when you use Loft Logic.

Once you are happy that we have answered all your questions and have accepted our quote, we will arrange a convenient appointment for our architect to visit you.

In this period, it is a good idea (if you haven’t already done so) to speak to your neighbours about your loft extension and the progress of works. You will need written consent from your immediate neighbours that they are OK for you to proceed.


The architect will take measurements and observations of your home and loft and then prepare detailed plans for you to discuss with our consultant. This usually takes two to three weeks. Once you have approved the plans, we will apply all the structural calculations/specifications and submit them to your Local Authority for approval. This stage takes between four and six weeks if planning permission is not required and up to twelve weeks if it is. Most first time extensions to houses do not require planning permission for up to 40-50 cubic metres (average-sized extension). Please note, this may not apply if your home is either; in a conservation area, listed or at the junction of two public highways. Flats require planning permission. This is a good time to completely clear the loft of those items you have been hoarding over the years! We would ideally like to begin construction with a completely clear loft space, but if you have difficulty with this, we can help you with removal and arrange skips for unwanted items nearer the project start date.



All planning applications and regulations are professionally managed on your behalf by Loftlogic. Draft plans are submitted to your Local Authority for determination under Section 63 of the Town and Country Planning Act General Development 1990.

Building and Fire Regulation plans are submitted to your Local Authority Building Control department for appraisal. The structural calculations are sent to the Structural Engineers department for checking and approval. Upon approval, we issue a Statutory Commencement Notice in accordance with the Regulation 14 of the Building Regulation 1985 (amended 1994) Act.

Throughout the project, the work will be inspected approximately three to four times by your Local Authority’s surveyors, who will double check that specifications, materials and construction methods are correct and certified.

At the outset we obtain the following permits from your Local Authority prior to the works commencing: i) Skips & material use and storage on the highway (Local Authority Highways Section), ii) Waste disposal containers (New Roads and Street Works Act 1991).
