Refurb and Extending of Semi-D... Help!

mapera

Hi There,
Hopefully I can get some help here, Im new to this building stuff. We live in a standard semi-d in Dublin, built in the 1930s, and are planning a refurb and extension job. It's a 2 storey extension, so includes extending the hip roof over the extension. The current property is approx 100 sqm, and the extension would be a further 90sqm. We could also consider converting the attic, (price permitting) there is plently of headroom.

So I want to get some prices that will help with designing in a practical manner. Effectively I have a budget, and while that cant move, the design can.

So first I'm trying to put together a list of works that need to be done, with the intention of hopefully getting feedback on A) whether I have everything, and how much we might expect to pay, and the most cost effective way to approach the different jobs (e.g. recommended heating systems/window suppliers/etc.).


- Demolish existing garage
- Remove designated internal load bearing walls in current house
- Build foundations for New Extension & Replace current suspended floor with cement floor (our architect has recommneded this replacement, not entirely sure if it is necessary?)
- Blockwork to new extension
- Extension of roof work
- Install heating system. Currently considering:
- solar power with suitable backup heater
- stove with back boiler
- Install underfloor/rad heating
- Replace external windows and doors, and add windows and doors to new extension
- Add dry lining insulation to existing house
- Add new internal walls to current house
- Rewiring 1st Fix
- Modify Staircase
- Replace internal doors
- Plastering
- Installation of Kitchen
- Installation of bathrooms
- Rewiring 2nd Fix
- Finishing

Thanks in advance for any help... PMs of recommendations welcome.
Regards,
Alan
