Kitchen Design & Extension

Providing a full building and refurbishment service, Onica Carpentry can assist with the design and planning of your new kitchen including any extension work required. We will work with you to source your new kitchen from units to flooring and we will discuss the project with you at every stage.


Onica Carpentry specialises in the design and installation of bathrooms, shower rooms and wet rooms delivered to the highest standard and within budget. We can help you select and source your bathroom suites as well as tiles and flooring.

Summer Houses

A summer house is not only a great garden feature but also a standalone extension for your home, giving you options to use that space in a creative or functional way.

Loft Extensions & Conversions

Onica Carpentry will bring their carpentry, joinery and other professional skills to ensure your loft extension fulfils your brief. We will work with you to ensure this process is as smooth as possible and help you achieve the additional space you need.


Decking will help to transform your garden and is a great way to make the most of your outdoor space. Onica Carpentry can provide the shade or colour of your choice. Don’t let the chance for a barbeque or a relaxing evening with a glass of wine slip you by.

Office Space

It’s important to have an office or work space which fits your individual needs and which makes the most of the space you have. Onica Carpentry will assist you with planning the area and will then create the office space which works for you.

Ioan is a hard working carpenter, he is always on time with his projects which are always completed to the highest standard possible.
