Transforming Tresillian Wollstonecraft

Tresillian’s new $16.4m parenting centre at 25 Shirley Road Wollstonecraft is nearing completion and will soon be welcoming the first parents and their babies to experience world-class care in a state-of-the-art facility.

The new early parenting support Centre, located at the rear of historic Carpenter House, has been thoughtfully designed and includes a 14-bed residential unit operating 7 days a week where parents can live in with their baby or toddler to receive specialist advice and support with issues such as an unsettled baby, breastfeeding and postnatal depression and anxiety.

Each room is beautifully appointed and includes private ensuites and adjoining sleeping areas for babies and their parent. The development also includes disability access rooms and double rooms for parents with more than one child.

Expanded day services will run from Monday to Friday from 8.30am to 5pm and visitors will find dedicated children’s play areas on each level along with spacious recreational areas overlooking the city and harbour for gatherings and parent education sessions.

The Centre is accessible from an internal lift connecting to the underground 12-space Staff carpark that includes 8 electric car charging stations. Public access is via a spacious boardwalk from Shirley Road to the elegant foyer of the new Centre

The opening of the Tresillian Wollstonecraft early parenting support Centre marks a historic milestone in the organisation’s 105-year history. We look forward to welcoming new generations of parents and their babies from across New South Wales to Tresillian Wollstonecraft and delivering on Tresillian’s vision to ensure every child has the best possible start in life. Rob Mills, CEO, Tresillian


  • Why is Tresillian redeveloping 25 Shirley Road Wollstonecraft?

    To provide parents with babies, toddlers and their families with state-of-the-art facilities including a new 14 bed residential unit that will operate 7 days a week. The new Centre will enable parents and their baby or toddler to live in for a 4 night/5 day period to receive specialist advice and support. The redevelopment will provide extra day services to allow more parents and their baby or toddler to attend along with expanded education and counselling programs. The Guthrie Early Learning Centre will also benefit from upgrades including improved playground equipment. Historic Carpenter House will be renovated and the original façade will be reinstated.

  • How much will the redevelopment cost?

    Approx. $16.4m

  • How is the redevelopment being funded?

    The redevelopment is being funded through the combination of a NSW Government funding grant of $500,000, corporate sector donations, philanthropists, Tresillian fundraising activities and some of the proceeds from the sale of Tresillian’s Willoughby site.

  • Does the redevelopment have Council approval?

    Yes, North Sydney Council and the NSW Government have approved the project.

  • Will the Tresillian Centre close for the redevelopment?

    No. The redevelopment will be undertaken in stages. This approach will minimise any disruption to Tresillian clients and staff and Guthrie Early Learning Centre clients. Safety throughout the redevelopment is a key priority and Tresillian will continue to inform and update all stakeholders as the project progresses

  • Will the Guthrie Early Learning Centre close during the redevelopment?

    No. Guthrie Early Learning Centre will continue to operate throughout the redevelopment.

  • How will traffic be managed during construction?

    Neighbours will be informed of any changes to road access or parking during the redevelopment.

  • Where will construction workers park?

    Where possible, construction workers will be encouraged to catch public transport. Those who need to drive and bring their equipment to the site will need to respect street parking availability and time limits.

  • Has a construction certificate been issued for the works?

    Yes, Construction Certificate No. 210315/02 for the Main Works, was granted on 8 December 2021.

  • How long will site excavation take?

    Excavation will be undertaken at specific stages during January to April 2022. A timeline will be included in each community newsletter outlining the estimated duration of excavation works. Please note that timelines for excavation works are approximate and subject to change for a variety of reasons including if it is unsafe or unreasonable for the works to continue due to unsuitable weather conditions.

  • How will construction noise be managed?

    HPAC is adhering to the project’s Construction Noise Management Plan as required in Condition 31 of Development Consent 326/17. During excavation works, HPAC will be using a combination of excavators ranging in size from small to large. Where possible, a large excavator will be used to help minimise the need to use rock hammers. This approach will help to reduce noise and the timeframe in which excavation works will be completed. Smaller excavators will be used as required to access restricted or tight site areas. Other noise management strategies include: - All excavation equipment will be fitted with sound attenuation mufflers - Machines will be turned off when not in use - Acoustic monitoring equipment will be utilised during excavation to log acoustic levels - HPAC will implement a ‘no loud radios policy’ on site - HPAC will monitor and address issues quickly if workers are found to be unnecessarily yelling, singing or using inappropriate language on site - All works will be delivered in accordance with North Sydney Council approved construction hours

  • What are the North Sydney Council DA approved construction hours?

    General Construction Works: 7am – 5pm Monday to Friday and 8am-1pm Saturdays; Demolition and Excavation Works: 8am – 5pm Monday to Friday

Hoardings and scaffold have also been installed around the construction site with shade cloth affixed to the scaffold to mitigate dust and provide privacy to neighbours. Odour suppression measures will be carried out as appropriate to minimise any impact to adjoining properties.

  • How will vibrations arising from construction be managed?

    All works will be undertaken in accordance with the ‘Interim Construction Noise Guideline’ published by the NSW Environment Protection Authority, to ensure excessive levels of noise and vibration are mitigated. HPAC will check vibration monitors as required and in accordance with the Construction Noise Management Plan which was prepared in accordance with DA Condition 326/17.

    No. All construction works will be delivered in accordance with the approved Development Consent 326/17 and in line with North Sydney Council’s permitted construction hours.

    To support the children’s nap time at Guthrie Early Learning Centre, HPAC may implement quiet work periods between 12.30pm and 2pm Monday to Friday as required and agreed with the Guthrie Manager. These quiet times are an initiative of HPAC and Tresillian and not a Council DA condition of consent.
