Our projects

We’re excited to be involved in a range of civil and structural engineering projects across New Zealand. You can find out more about some of our recent projects below. 

Wallaceville, Upper Hutt


Wallaceville Developments Ltd


Wallaceville is a 700-lot residential and commercial development just north of Trentham Racecourse in Upper Hutt. 

We've carried out the civil engineering design resolving the site’s infrastructure constraints  along with project management, construction observation, and completion reporting allowing the 63ha former agricultural site to be redeveloped for residential and commercial purposes.

Our design works have included earthworks, roading, wastewater, stormwater, water, power and phone layouts, as well as the overall masterplanning of the site. 

There are currently 163 lots completed across the first 4 stages at Wallaceville Estates with another 87 under construction in stages 5 and 6.

We are currently designing the next 2 stages. 


Envelope have been involved in this ongoing project since mid-2016.

Project value

$ 45M


16 Jessie Street, Wellington


Geppetto Properties Ltd


We helped Geppetto Properties Ltd to realise their plans of converting their Wellington CBD warehouse into three new commercial tenancies.

We completed a seismic analysis and designed a strengthening scheme for the warehouse. In addition, we completed the structural design of various structural elements including a new slab step down to allow direct access from Jessie Street, openings in the existing precast concrete panels, a full height glazed wall/window around the stairwell, a steel stair case with glazed balustrade and a fire wall. 

This property is now a thriving hub of commercial space, and Geppetto Properties are delighted to be providing premises which draw new businesses to the area. 


May 2016 - July 2017
