1. Architectural drawings and Planning Permission

The first step is to design your proposed works with consultation from our architectural team, (if you already have this then great you can move to the next step).

Our team will be able to advise on your proposed works and the feasibility of obtaining planning permission. Once you’ve agreed the layout and scheme, our architects get to work and produce initial drawings. Once you’re happy with the set of plans our team submit the relevant planning application.

2. Structural/Building Control Plans, Pre-Construction Design & Party Wall matters

Once we’ve received planning permission, our team will get to work on producing structural drawings which are produced by a Structural Engineer who specifies all the structural elements required to ensure the building is structurally sound and safe. Whilst our Architectural team will produce a detailed set of drawings ‘for construction’.

Our project construction team will also discuss your final finishes to your proposed works, including layout, electrical points, wall & floor finishes etc.

This is usually the time where Party Wall matters commence if the works are applicable under the Party Wall etc. Act 1996. Our team can offer advice and assistance in issuing party wall notices.

Before commencing on-site, it is a legal requirement that we appoint a Building Control officer to oversee the works, many clients tend to use the local authority building control department or independent building control officer. Their job is to ensure the building is being built to Building Regulations and generally visit the property during the works at set intervals to sign off each stage.

3. Let’s Build

It’s now time to build and handover to our expert construction team to turn your vision into a reality.

We are flexible in adapting to changing requirements that you may wish to carry out, after all, once you’ve seen the new space you may wish to tweaks aspects of the final finish. Our friendly team will be at your service during the build should you have any questions.

You receive information with our ‘Customer Pack’ which will detail out:

  • How long the construction period will take, for typical loft conversion this is usually three months but can be much shorter.
  • A Schedule of key dates and a stage by stage payment schedule to help you plan and budget
  • Process of instructing ‘change orders’ or additional works.

4. Sign-off, warranties
& Completion Pack

Once the works are complete, you will receive the Derry Design and Build Completion Pack. This includes:

  • A set of “as-built” plans.
  • Building Control sign-off (where the BC is appointed by Derry Build)
  • Derry Design and Build Completion Certificate
  • User manuals for equipment installed
  • Final Account Certificate upon final payment.

5. Feedback

Finally, once you’ve handed over to your satisfaction, we’ll ask you to provide feedback on our service, product and quality. Perhaps even a testimonial, after all, our reputation is our customers.
