Our Process

The Modern Extension Project Process

Project suitability confirmation with preliminary structural plan drawing compatible with your existing house.
Preliminary internal layout plan drawing and associated specification with current market adjusted costs for the project.
Full project specification and works documents with associated costs structure and agreed payment schedule and contracts.

Data Capture & Design

Off site

1. Site survey data capture and export apx 1 day ( On site )

2. BIM modelling and structural design, 3D advanced AutoCad and Tecia ( Off site)

3. Full suite of client drawings for sign off to include:

  • All structural components
  • Assembly order
  • Aesthetic design plans and elevations
  • Foundation base and drainage plans
  • Internal plan layouts to include kitchen, w/c, utility, mechanical and electrical, flooring and tiling with quantities (Off Site)

Prior to On-Site Commencement

Off site

4. All structural components gone to order and manufacture from within the CAD 3D model prior to on-site commencement.

  • Structural steel super structure
  • Engineered twin leaf walls
  • Roof sub structure, flat or pitched
  • Roof windows, flat or pitched
  • Windows and doors
  • Structural envelope clear cavity rigid insulation
  • Timber engineered inner walls
  • All internal walls and ceilings pre dry walled with all first fix services pre-pulled
  • All aluminium finishing trims and rainwater collection systems pre-pressed and sprayed in project RAL colour (Off site)

On-Site Project Commencement

On site

5. Groundworks, drainage, foundation, paths and floor slab (On site)

6. Transport assembly and erection (structurally sealed) on average week 2 (On site)

7. Removal back wall of house, remodelling to existing and skim (On site)

8. Complete first and second fix mechanical and electrical (On site)

9. Complete second fix finishes i.e. doors, floors, tiling, sanitary wear (On site)

10. Kitchen hook-up services to all second fixes i.e. utility, w/c (On site)

11. External final coverings and sealing (On site)

The Modern Extension project process translates in up to a 60% on-site time saving re: new build and existing house structural support, fully building and structural regulation compliant.

Designing, engineering, manufacturing and erecting distinctive home extensions in Ireland and now the UK for over 30 years. Our manufacturing facility employs the latest in pre-cast concrete form engineering, capable of casting curved moulds with glazing openings both inverse and linear. In the case of our timber-engineering department, we can cater for all manner of geometry. This has proven particularly relevant to the UK market in creating imaginary and contemporary roofing forms for our clients.

Limited only by imagination, our innovative process can engineer and install to your own pre-existing plans or our newly developed ones. What’s more, our system can replicate any structural designs that may have caught your eye.

A service designed primarily, but not exclusively, for planning exempt customers, our process employs the very latest in off-site home extending technology both hard and soft,

Most modern extensions require significant structural steel for true open plan living with regard to the removal of the structural rear wall but also to be current building regulation compliant, all new external walls must be twin-leaf with an insulated clear cavity enveloping the structural envelope. However these type of walls are not suited or designed for clear span glazing weight transfers. This has particular regard for any new walls with large windows and door openings – hence most modern designs now need the entire super structure in steel. However with steel being a highly regulated industry, it makes sense to begin that process prior to project commencement and not half way through the on-site linear building process adding weeks to the build at the worst possible time for you and your family as most likely at that point of the traditional on-site build, you will have little or very reduced services with no back wall propped up on acrows as the steel only then begins its regulatory design and manufacturing process as is market norms within the sector conforming with 2014 CE marking engineering and building regulations.
