Brandon House Hotel Returns to its Full Glory

Most conservation challenges are complex and many difficult challenges have arisen during the Works. Isabel Barros Architects are proud to have achieved a fantastic result through good collective teamwork and strict budget control.

River House – Kilkenny

The site presents a number of challenges, including a house over 150 years old, the proximity to a Special Area of Conservation (River Nore), the existing topography, and so on…

The Secret Guide to Deal with Architects – Take 10

Good or bad! Your Architect wants to hear from you. Your Architect wants to know if you are happy with his/her services, how can he/she improve or if there is a better way to do things.

Building Costs in Ireland 2018

Useful information to guide you on the costs for your construction project in Ireland. This will help you to estimate an approximate figure for your building costs.
In 2018 construction tender prices are still increasing, this emphasises the importance of budgeting for future construction inflation in feasibility studies and cost plans.

Advantages and Disadvantages of Timber Frame Construction

 

Advantages of Timber Frame Construction

 

  • Recyclable
  • Renewable

Timber is classified as a renewable material, as the principle holds that if a tree is felled another is planted in its place. As long as this balance is maintained, the supply will be sustainable.

  • Low embodied energy if constructed in local timber
  • Reduced construction waste through efficient controlled manufacturing
  • Low volume of waste on site requiring removal
  • Quick build time

A prefabricated timber frame can be erected on site faster than a comparable brick and block construction. However, timber frames may require additional time for their design and fabrication, which can lead to a longer wait before work begins on site. 

  • Reduced site labour
  • Reduced time to weather the structure
  • Earlier introduction of following trades

The quicker erection time enables interior trades such as plastering and electrical wiring to begin work earlier in the build programme, as the interior will be exposed to weather for less time.

  • Can be built to exceed 60-year design life
  • Energy efficient when constructed to current standards
  • Fast heating due to low thermal mass

Their low thermal mass allows spaces enclosed by timber frames to heat up more quickly than masonry construction, however they will also tend to cool more quickly.

  • Reduced time on site reduces environmental nuisance and disruption to local residents
  • Engineered product
  • Factory controlled quality assurance in fabrication

Off site fabrication can allow higher quality to be achieved.

  • Efficient use of material due to controlled engineering and fabrication
  • Reduced construction time translates into reduced risk exposure

 

Potential Problems with Timber Frame Construction

 

  • Traditional procurement process
  • Additional design and engineering time
  • Modification of general arrangement drawings if based on masonry construction
  • Lack of experienced builders and erection crews
  • Lack of experience of following trades
  • Transportation and carriage access
  • Exposure to weather before enclosed
  • Work of following trades
  • Deficiency of site quality control
  • Combustibility of timber requires vigilant quality control to achieve required fire rating of separating and compartment walls

The fire resistance of timber frame buildings is achieved by a combination of the lining material, the timber structure and the insulation.

Additional fire protection can be given to the frame by the boarding used to clad it and fire stops installed to prevent spread through the cavity.

Recent fire tests commissioned by the Timber Frame Industry and the ITFMA showed that in general a 15mm Type A plasterboard is required to meet the Fire resistance of REI 30 for external walls (see detail).

The risk of fire can be increased if timber frames are not erected correctly, and during construction prior to fire protection being installed.

  • Susceptibility to decay of timber when exposed to excessive moisture

Timber frame structures must include a vapour barrier between the lining of the inner wall and the insulation, to prevent vapour passing through.

  • Acoustics

Timber frame structures may not achieve the same level of sound insulation as concrete or masonry as they are not as dense.

Clonmore House – Wexford

 

One thing we can take it from granted when we visit a rural site in Ireland – green pastures!

On our first visit to this site we were greeted by our young clients and Bel, the sheep.

It was easy to get lost in the stunning open views of the hills but Bel reminded us this was a working farm.

 

 

This site in North Wexford has a gentle south-facing slope and it offers the ideal location for our farmer client to build his future family home.

 

 

Re-inventing the traditional farmyard layout

The proposal was strongly inspired by the rural location, the farm environment and the close proximity to existing farm buildings. The traditional farmyard layout (see no. 1 below) was the starting point for the new scheme.

 

The existing site contours are used as the regulating lines for the new layout. They shift the smaller volume until it is stopped by the 2 storey volume (see no. 2 above). The result is a layout that easily meets the current lifestyle of its occupants while reflecting cultural values of the traditional farmyard layout.

 

 

The main living spaces open up to south to enjoy the best views and passive solar gains. The windows frame the views to the surrounding farmlands and hills. The bedrooms face east to enjoy the morning light. The living room connects to an outside space that is sheltered from the weather and can be used all year around.

 

 

A palette of natural and man-made materials is proposed. Stone walls feature throughout the house recalling the character of agricultural buildings. The zinc has a strong agricultural feel that  balances the composition whilst connecting the traditional gabled volumes. This is contrasted with the stone and white render which act as contemporary, yet rural materials.

The layout optimises the use of solar energy and aims to achieve an A3 BER rating (50 kWh/m2/yr).
