Let`s build your dream Granny Annexe

Couple of reasons to build with TRJ Construction Ltd:
• Local specialists
TRJ Construction specialises in bespoke SIP garden annexes built around the site and the agreed brief. Discuss access, installation arrangements and the programme for your property.
• Experienced
Costi has over 25 years of construction experience. TRJ Construction Ltd was founded in 2012, with SIP installation experience dating back to 2001.
• Quality products
Materials are selected around the project specification. Cladding, glazing, roofing and decking have product-specific inspection and maintenance requirements.
• Family care
We are a family business, with strong family values. We will build your Granny Flat with the same care and attention as if it were for one of our own family members.
• Precision
Our design and build process is seamless. Using the latest project management technology ensures nothing will be missed and your home will be built to schedule, budget and scope.
• No hidden costs
Our whole process is very upfront, honest and transparent, so there are no hidden costs. Your new build will have a fixed price contract, detailing all inclusions, and an agreed time frame.
• Complete project management
We take care of absolutely everything, from gathering information required for submitting building consent, to organising utilities – and even landscaping if needed. We can also future proof your build for disabled access.
