Building Regulations

Create a safe and healthy home environment for your loved ones with these technical drawings.

What are building regulations?

They’re a set of statutory requirements that all buildings must meet in order to create a safe and healthy environment to inhabit.

They cover everything from the structure, thermal performance, sound proofing, drainage, all the way to fire safety - to name just a few!

To ensure your project is in line with UK building regulations, you must commission a set of technical drawings of your proposed build, demonstrating all legal requirements have been met.

This drawing package will be prepared by a Resi technician, but will also need input from other specialist professionals, such as a structural engineer, party wall surveyor, and CCTV drainage surveyor.

At Resi, we can help you find trusted professionals and then consolidate their work into a building regulations package. We will also help you through the application process with the local authority or approved building control inspector.

This first conversation between you and your assigned Resi technician will be an opportunity to ask us any questions you have on the whole process, and shouldn't take longer than 15 minutes.

Choosing your professional consultants

If you haven’t already got the rest of your professionals in place, we’ll introduce you to our trusted third parties. This includes: structural engineers, party wall surveyors, and CCTV drainage surveyors.

Initial Third Party Work

Your selected professionals will carry out their specialised assessment of both your home and our proposed design. They will most likely require a home visit, in order to inform their work, which will then get passed on to Resi.

Resi Drawings

When all the information has been supplied to Resi by your third party consultants, your technician will get to work consolidating everything into a set of highly detailed architectural drawings.

Revisions and feedback

We present our work to both yourself, the structural engineer, and the approved building control inspector, making any revisions from the feedback we receive.

Once edits have been made, we package up our drawings, ready for submission. This gives you a comprehensive drawing and specification package, which will ensure your project is built to the correct and approved standards laid out in UK building regulations.

Next Steps

Time to get ready for construction

Once you’ve received building regulations approval, your next step will be to put your project out for tender. This is when you’ll select the contractor who’ll construct your project.

It is useful to note at this stage that your home improvement may require further decision making when you get to site. If for example you have any external finishes requiring specialist input, or have any complex junction details, your contractor can make adjustments to your design.

This also gives you the freedom to make minor changes on site with the agreement and approval of your contractor.

At Resi, we offer a complimentary Connect service, whereby you’re introduced to vetted contractors in your area. This ensures you're in safe hands for the rest of your home journey.
