Architect: Extensions and Energy Upgrades

As part of our unique design service for extensions and smaller jobs, we will show you how to save around £500 of your energy bills with a payback of about 2 years.

planning permission

From the 28 May 2014 the Planning Permission Fee for an Extension or Alteration is £285. Some types of Extensions or Alterations do not require Planning Permission or a Fee. This is called Permitted Development. We can advise you on Planning Permission. Planning Permission if required should be gained before any work starts on site.
You can also download a useful guide from the Planners Website using the following link: http://www.planningni.gov.uk/index/advice/advice_apply/advice_apply_homes/advice_householders_guide.htm

building control

Building Control Plan Approval should be gained before you start any works. From the 8 April 2013, the Building Control Fee for an Extension up to 20m² is £120. Other types of Works attract different Fees, which we can advise on. More information is on the Councils Website:  http://www.derrycity.gov.uk/Council-Services/BuildingControl

We have gained the skills necessary to offer a unique high quality design service in low energy sustainable buildings: 

Architect
(Over 20 years experience in residential design)
SAP Energy Assessor 

(Builds an energy model of your dwelling to ensure a cost effective design)
Thermal Bridge Assessor 
(Calculates and minimises heat loss around doors, windows and other junctions which can account for up to 25% of heat loss)
Air Leakage Survey
Around a third of heat loss is through air leakage. We shall check for air leakage and minimise these losses.

Thermal Camera Survey
We shall use a thermal camera to ensure there are no gaps in the insulation and construction is of the highest quality.
Energy Performance Certificate
We can issue an EPC at the completion of the work.
