Our professional and friendly site managers will visit your home to carry out a no obligation site survey.

During this meeting, they will be able to advise on what type of ideas and layout is feasible for your home as well as take essential measurements required for your quotation. Once this information is collected, you will then receive a free no obligation quotation within 2 working days.

Once you are happy with your quotation, a contract is drawn up and signed agreeing to complete your project for a fixed price and set timescale.

You will receive a Schedule of Works, Payment Plan and Progress Report on you project.

If required, a member of our architectural team will visit your home to complete a survey and produce a set of plans. We can also help with structural calculations and dealing with building control as well as submitting your plans under permitted development or full planning.

A party wall agreement is requited if your home has a wall that is connected to another property on either side. Each neighbour will have to be informed of the proposed works using a party wall notice form at least two calendar months before the start of the build. At Crown Designs, we can provide advice on this process and if necessary put you in touch with one of our certified Party Wall Surveyors, if needed.

Once all planning and permissions are granted, Crown Designs can start the build stage of your project. You will be assigned a dedicated Project Manager who will arrange regular meetings to review progress and keep your project running to schedule.

Once your project has finished, Crown Designs will ensure that all relevant certification including building control completion certificates and our 10 year guarantee are given upon completion.

Loft Conversions

loft conversion is the process of transforming an empty attic space into a functional room, typically used as either living accommodation or storage space.

Loft conversions are one of the most popular forms of home improvement in the UK as a result of their numerous perceived benefits.

House Extensions

Why move when you can improve? There are lots of reasons to extend, whether you want to create more space, add value to your home or just love the area in which you live.

The increasing cost and hassle of moving combined with uncertainty in the property market makes staying put an attractive prospect.


Transforming a space doesn’t always require a major structural work. A new kitchen, bathroom, a different colour scheme, or a better use of natural light can all create a wonderful space to live or work.
