about us

In 1979 Douglas Mackay set up a business to provide the design, supply and installation of quality kitchens and bathrooms……..


The aim of this business was to meet the requirement for properly project managed installations, where the client could rely on one person to take full responsibility for the installation, from conception to completion.

This business blossomed, with work throughout Cornwall and, by request of those who had holiday homes here in Cornwall and main homes elsewhere…. throughout the rest of the United Kingdom….London, The Midlands and Scotland.

The business grew.  

Sometimes the kitchen or bathroom required more space….an extension….we began to do extensions.

One or two clients wished to have barn conversion….we began to do barn conversions.

One day a client asked us to design and build a house….we began to do new house projects. 

The basic principal  remained the same…we would sit down and listen to what the client had in mind. 

We would hone it with our knowledge and experience. 

Design plans would be drawn up….anything from a new sink to a new house. 

Necessary permissions/inspections would be sought and approved and the whole project , however large or small, managed to completion. 

Sometimes we even hang the curtains!

John Myers, Douglas’s son in law, has been in the construction industry for more than twenty years and involved in this business for eight years. He has proved himself very capable of taking over the reigns. Douglas Mackay would seriously like to spend more time fishing and gardening, but still very much keeping a ‘hand in’ the design and planning aspects of our projects.

So, towards the end of 2014 the decision was made to form a new business for John to carry forward…

                                        …….. M & M DESIGN & BUILD.

The basic principals of the business remain the same….after thirty six years. 

Properly managed projects.

Full design to the clients requirements.

All planning/inspections/regulations, obtained and observed.

Supply of quality goods and materials. 

Execution of all aspects/trades, tightly quality controlled to a high standard.
