The project was to look similar to a recent project that they had completed nearby, and they would be using the same architect team to oversee the project.
On our initial site visit various restrictions and complications were identified which would have to be managed throughout the design phase. These include low ceiling heights in the apartments, very little external space for equipment and the clients need to optimise the rental space revenue. It was decided early on to demolish the communal area and start again, which allowed us more scope to design the area to the latest regulatory standards.
To meet all the site restrictions and client requirements we initially proposed 4 small Air Source Heat Pumps (ASHP) to be located externally around the outside of the building. However, this came at a high initial cost as it was more expensive to purchase 4 small individual units than one larger unit.
Before After
Through various meetings and costing exercises it was decided to sacrifice one apartment and use it as a plant room instead. This piece of work enabled the client to understand and consider his options so that he got the most cost-effective solution.
The design of the communal area was developed alongside the structural engineers and the architect to provide a double-height area with an open roof which provided lots of natural light and access to the garden area.
The large volume of space and no roof void meant that we had to be innovative with the heating and ventilation of this area. The final solution was to provide heating through radiators and mechanical ventilation with heat recovery (MVHR) through fans located in the adjacent roof space of the existing building. This means the heating is easily controlled and the ventilation fan noise is kept away from the communal area.
The project also saw us provide drawings, equipment schedules and specifications for the fire detection and alarm system, hot and cold-water systems, sprinkler, drainage, lighting, power, data and nurse call systems.
The final design provided the electricians and plumbers with accurate drawings, a list of equipment to purchase as well as a specification that informed them of the installation standards to meet and the testing to be completed prior to handover.
Additionally, the client was provided with a design that had a cost-effective heating system that is the optimum size and location for the building.
