About Southbuild

When Paul and Leanne Southorn started the business in 1996, Paul was the company’s only builder and Leanne was the part-time office administrator.

In 2010 we changed the company’s name and rebranded its image. As for innovation and quality workmanship, it was business as usual at Southbuild, or SBL as it’s also known.

Our team of six is deployed on sites all over Christchurch. Paul is the overall project manager and works on the tenders and job scheduling in conjunction with Leanne who manages invoicing, staffing and legislative requirements.

We’ve developed a strong reputation and loyal client following because we deliver on our promises and stand by our work.

We listen to our clients’ needs and requirements, we encourage and maintain open and ongoing communication with clients, suppliers and subcontractors, provide workmanship of the highest standard, keep to timelines and stay within budget where practicable.

Our carpenters are qualified experts with experience in residential and commercial developments, office renovations, commercial maintenance, retail and restaurant fit-outs, residential alterations and extensions – including kitchens, bathrooms, structural interior work, concrete work and decks.

We’ve established excellent working relationships with suppliers and subcontractors who share our passion for quality work and finishes.

We work with a wide variety of building products, price jobs with the best materials and endeavour to source the best prices for our clients.

Since early 2011 Southbuild has been actively involved with post-earthquake repairs in the Christchurch Rebuild. As nominated accredited builders SBL has worked in the Fletchers Emergency Works and EQR programmes with various architects, PMOs and insurance companies – in both the residential and commercial sectors.

As Registered Master Builders, we have a broad and sound knowledge of the carpentry and building project management required for commercial and home renovations, alterations and extensions.


We are able to complete to a very high standard large and complex building projects such as major renovations, structural extensions and structural and internal changes. We also take on smaller projects such as renovating kitchens, bathrooms and installing window joinery. We can work with a wide range of different building products.


Over the years Paul and Leanne have developed positive relationships with a variety of reliable suppliers and subcontractors you may need to complete your project. Or if you prefer we can work with your existing suppliers. We can work with or without involvement of architect depending on the scope of work.

Cost Effective

It is important that you feel assured of the quality of the materials we supply as well as the high standard of our workmanship. We prepare detailed quotes and endeavour to price jobs with the best materials at the best price. Where possible we request as many as three competitive quotes before selecting our final suppliers.


We pride ourselves on tight co-ordination and good communication so your project is completed quickly and efficiently minimising inconvenience to you. Our builders realise their building site is your home or business and show respect at all times being punctual, polite and as tidy as possible.


At all times Paul and Leanne are available to discuss any concerns or questions that may arise during the job and appreciate any feedback you offer.
