Renovations and Additions

Are you looking for highly skilled building specialists you can trust to renovate your home?

Concept Design Build is a trusted building company specialising in high-quality architectural home renovations and additions.

With over 20 years’ building experience in the residential and light commercial sector, we have completed a varied array of successful architectural renovation projects.

Our Director, Richard Ushaw, has been a property investor since the age of 21. He’s an expert in buying and renovating properties.

He understands that renovating your home will most likely be one of the biggest investments you will make in your life. We guarantee that whether you want to add space for your family or you want to turn a profit, your renovation project will not only improve your home and lifestyle, it will also add value to your property.

We work with a registered valuer who can give you a valuation on the property (which is great if you need finance for the renovation,) and they will also give you an estimate based on the work we are going to carry out.

Whether you need an additional bedroom, an extra bathroom, a more functional kitchen, or a larger area for your growing family, we can help you transform the look and feel of your property, add space and light and modernise the flow of your house.

Our team of skilled professionals will ensure that your renovation project is as stress-free and smooth as possible, as well as of exceptional quality, on time and within budget.

Concept Design Build is a member of the New Zealand Certified Builders Association, and all our builders are Licenced Building Practitioners. You can stay assured that you and your home are in the hands of a highly skilled and qualified team.

We work closely with local designers to provide you with the full concept design build along with a no-surprises fixed price.

For your complete peace of mind, we offer a comprehensive project management service to ensure your building project always runs smoothly, on time and within budget.

We believe that transparent communication is paramount to the success of the project. We will send you regular updates, schedule regular site meetings, and we will provide you with personal access to our real-time project management software.
