New builds & Extensions

All building works are undertaken, from complete builds and alterations to impact damage. We have extensive experience in making major alterations including supporting entire buildings and installing structural steels to demolishing supporting walls.

A recent example of this was at Stanwell Road Penarth. This complex expansion project involved removing back of house and whole ground floor corner, This required the upper floors to be supported whilst installing nine pairs of spliced beam anchors to the walls under a central row of spliced beams. The supporting wall was then demolished to create the larger retail unit.

Free Consultation Visit

Occasionally our clients have not yet obtained planning permission before they come to us, which is why we offer a free consultation visit. This allows us to listen to your ideas and discuss the most suitable and cost effective extension for you and your property. Following this initial meeting we will then provide you with an estimated project cost based on your requirements.


If you decide to proceed with McCann Building & Ground works we will provide you with a free Project management. We can also apply to the local authority for planning permission approval and building regulations on your behalf if you can appoint an architect.

In some instances planning permission isn’t always required and work can begin in as quickly as 2-3 weeks.

Once drawings have been finalized and planning process underway we will provide you with a full specification and fixed quotation which is valid for 60 days.

Installation Whatever the size or scope of work required you can be assured that you will have a full-time project manager or supervisor on-site at all times.  All of our tradesmen and appointed contractors are fully qualified or NICEIC, Gas Safe approved and work will be undertaken by a highly skilled and experienced workforce.

Disabled & Mobility Adaptations

Following new legislation making it a legal requirement to take measures to allow disabled access to commercial and public premises, we have been carrying out more and more of this type of work. Expertise in this area is sought by many of our clients and the most common adjustments include the following:


  • Construction of ramps
  • Installation of hand or grab rails
  • Widening opening
  • Forming “Wet rooms”
  • Installing Disabled W.C’s

Loft Conversion

Loft conversions are becoming more and more popular and are often a more cost effective option when looking to extend your property.

A loft conversion can create that much needed extra bedroom, study or playroom and with the wide variety of options available we can guarantee the perfect solution to suit your needs.

Different types of loft conversion include:


The Dormer is suitable for when the existing loft space is of insufficient size for the proposed conversion. It creates additional headroom for the staircase and space required and is particularly useful if looking to create an additional bathroom as it will increase the height above fittings.


This option is often recommended for those contemplating the smaller loft conversion, perhaps for a single bedroom or study. As the necessary height is already available within the existing loft space, roof lights can be installed with minimum disruption.

Hipp to gable

In this type of conversion the hip roof is replaced with gable ends which greatly increases the usable floor space and height around the sides of the property where the hips once were.

Free Consultation & Design Visit

We offer all of our clients a free consultation visit where we will determine the feasibility of a loft conversation and the potential floor space.

There needs to be a minimum of 2.4m floor to ceil measurement to meet current building regulations, which can be created by lowering ceils on the floor below.

Once we have confirmed these requirements we will then take your ideas and work with you to put them into the design and floor plan.


On your approval of the design we will apply to the local authority for planning permission (if needed) and building regulations. Depending on the type of consent required, work could then begin in as little as 2-3 weeks from the submission of drawings.


Depending on the extent of work to be carried out, loft conversions usually take around 8 weeks to complete and we will aim to ensure minimal disturbance to you and the existing property throughout this time.

With McCann Building & Ground works you can be assured that all work is undertaken by a qualified and highly skilled workforce and our tradesmen are qualified or NICEIC, Gas Safe approved.


Underpinning is required when a building is subsiding or suffering from ground heave. Underpinning can also be used to enable basement construction by adding depth to the building’s original footings.

The success of any underpinning project is determined by the contractors carrying out the work. In most cases, once the work is completed it is back-filled again within a few days, so it is imperative the work is undertaken by a competent, trustworthy contractor.

McCann Building and Ground works guarantee all work is undertaken by highly trained and experienced staff who are fully supervised to ensure our high level of workmanship is maintained.

We mostly undertake traditionally excavated underpinning but can work to any engineer’s drawings.


Much of our alteration work involves supporting upper floors and often, entire buildings.

This is an area we excel in due to our extensive experience and one project to note is the Beach Road Penarth and St Michaels Road Llandaff C. This project involved supporting a 3-storey building whilst installing steels to allow the ground floor walls to be taken out for underground parking.

Other alteration work includes:

  • New Openings
  • Steel insulations
  • Chimney breast removal
