New Build vs Refurbishment: Different Approaches to Apartment Mechanical Services

Whether delivering a completely new apartment development or giving an existing residential building a new lease of life, mechanical services play an important role in the success of the project.

Both types of development present opportunities to improve comfort, efficiency and long-term building performance. The difference lies in the approach. New-build projects allow mechanical services to be integrated into a building from its earliest stages, while refurbishment projects provide an opportunity to assess existing systems, retain what works and introduce improvements that can transform the performance of an established property.

The Opportunities of a New-Build Development

Starting with a new development provides considerable flexibility when planning mechanical services.
Plant rooms, risers, distribution routes and equipment locations can all be considered alongside the architectural and structural design. This allows heating, ventilation, domestic water, drainage, air conditioning and controls to form part of a coordinated building services strategy from the outset.

Early involvement of the mechanical team can also help make the best use of available space, simplify installation and ensure systems are designed around the expected demands of the completed development.

Giving Existing Buildings a New Lease of Life

Refurbishment projects offer a different but equally interesting opportunity. Existing apartment buildings can often benefit significantly from improvements to their mechanical infrastructure, particularly where systems have been operating for many years.

The first step is understanding the building and its existing services. Rather than assuming everything needs to be replaced, a refurbishment provides an opportunity to establish which elements remain suitable and where modern equipment, controls or system improvements could deliver the greatest benefit.

This considered approach can help modernise a building while making effective use of existing infrastructure.

Making the Most of the Available Space

Space is an important consideration on every apartment project.

With new-build developments, service routes and plant areas can be incorporated into the original layout. During a refurbishment, the mechanical design can instead be developed around the building’s existing characteristics.

This is where experience and careful engineering become particularly valuable. Existing risers, ceiling voids and plant spaces can often be utilised effectively, while modern equipment can provide new possibilities for upgrading systems within established buildings.

Improving Building Performance

Both new-build and refurbishment projects provide excellent opportunities to improve energy performance.

For a new development, efficient mechanical systems and intelligent controls can be incorporated from day one. Within an existing apartment building, upgrading plant, controls or individual systems can significantly improve how the property operates without necessarily requiring every element of the mechanical infrastructure to be replaced.

The right approach depends on the building itself, how it will be used and the objectives of the developer or building owner.

Delivering Refurbishments Around the Building

Another important consideration is how refurbishment work is programmed. Where an apartment building remains occupied, mechanical upgrades can be carefully phased to help maintain essential services and minimise inconvenience to residents.

For vacant buildings undergoing wider redevelopment, there may be greater freedom to undertake more substantial upgrades to existing infrastructure.

In either situation, detailed planning and coordination allow the mechanical programme to work effectively alongside the wider refurbishment.

Designing for Long-Term Operation

Whether the project starts with a new structure or an established building, the objective is ultimately the same – to deliver reliable mechanical services that support the property for years to come.

Accessibility for servicing, equipment selection, system efficiency and future maintenance should therefore be considered throughout the design process. Getting these details right can make the completed building easier to operate and maintain.

The Right Solution for Every Apartment Development

New-build and refurbishment projects each bring different possibilities. A new development provides the freedom to create an integrated mechanical strategy from the ground up, while refurbishment offers the opportunity to modernise existing buildings and improve the performance of established mechanical systems.

Hartle has the mechanical services expertise to develop solutions around the individual requirements of each project. From design and coordination through to installation and commissioning, the focus is on delivering systems that are practical, efficient and appropriate for the building – whether it is brand new or being prepared for its next chapter.
