Feasibility Study of M&E Services For the Development of Two Apartments and Two Retail Units in Ripley

A Feasibility Study was conducted on behalf of our client that was converting an existing retail unit with storage space above into two separate retail units with two one-bedroom apartments above. The following M&E Services were reviewed and recommendations given for each:

  • Heating/Cooling
  • Domestic Water Services
  • Above Ground Drainage
  • Ventilation
  • Electrical Services

Review of the two apartments

Each apartment was to comprise of a living/ kitchen area, one bedroom, one bathroom and a connecting hallway. The apartments were accessed through a shared stairway to the rear of the building.


The apartments were assessed for their suitability for the installation of mechanical and electrical services to meet the current building regulations and British standards. This case study shows the options available to the developer and the recommended installation strategies.


We found that most services could be installed with little or no adjustment to the proposed layout. However, there were two areas that required resolution:

  a. An external drainage downpipe was required outside of the lobby, and the location had to be agreed and approved as it would cross the demise boundary.

  b. Early co-ordination with electrical and water suppliers was required to ensure that services were upgraded in time.


Review of the two retail units

Each retail unit comprised of a retail area, an office, kitchen and WC. One of the retail units was to have a small storage area. Access to the retail units was through the front door and potentially via the rear door.


Through assessing the retail units for the suitability for the installation of mechanical and electrical services it was found that most services could be installed with little or no adjustment to the proposed layout. However, two areas required resolution:

  a. Two external air conditioning condensers needed to positioned on the roof or on a rear facing external wall that would cross the demise boundary.

  b. To minimise the amount of work and equipment needed to remove waste water from the kitchen sinks it was recommended that they are moved to the opposite walls.

  c. Again, early co-ordination with electrical and water suppliers was required to ensure that these services are upgraded in time.


To minimise the running costs and reduce the carbon impact of the development it was recommended that consideration be given to solar thermal water heating panels on the roof for the apartment hot water services and a Heat Recovery unit be installed in the retail unit ventilation system.


Once the feasibility study was carried out we were able to give the client a budget cost estimate for the M&E Installation for the apartments and the retail units. This helped the developer not only to understand the cost of the conversion but also gave them confidence that the M&E Installation would comply with all regulations and would be completed on time.


After completing the study we were asked back by the client to complete the detailed design of both the retail units and the apartments.
