Construction company in Dublin, budget before design

Most builders design first and price later. Alder gives you a real cost for your house extension or renovation before a single drawing is commissioned. So every design you see is one you can actually afford to build. Our own trades then build it to the agreed figure.

How Alder differs from a typical Dublin builder

Two things separate us in practice. The budget is agreed before anything is drawn, and every trade on your site is Alder staff.

The Typical Route

Cost arrives last

1

Drawings come first

An architect is appointed and a full set of drawings is produced before any builder has priced the work.

2

The quotes come back high

Tenders land above what you set aside, because nothing in the design was ever tested against a real budget.

3

You redraw or you stop

Either way, months are gone and the design fees are spent. Neither outcome gets you a house.

The Alder Route

Cost comes first

1

Feasibility before design

We assess the house, the site and your brief, then give you a real cost range and the planning position.

2

Design built to that figure

Layouts, structural design and any planning application are developed to the budget you have already agreed.

3

Our own trades build it

Employed plumbers, electricians and structural staff on one programme, under one site manager, to the figure agreed at the start.

Common questions about renovations and extensions

Planning a renovation comes with many questions. Here are a few answers to help you understand the process before getting started.

Everything from the first costing to the final certificate. Alder covers feasibility, architectural design, structural design, planning applications, the build itself, and commissioning at the end. One contract and one team, so you are not coordinating an architect, an engineer and a builder separately.

We visit the house, look at the site, the structure and what you want to achieve, then give you a realistic cost range based on projects we have actually built. It is not a quote. It is a figure accurate enough to decide whether to proceed before you spend anything on drawings.

No, not for the core trades. Our plumbers, electricians, carpenters and structural staff are Alder employees. That is why we can commit to a programme and hold it, rather than waiting on trades booked across several other sites.

No. We work on whole spaces rather than single rooms, so extensions, full renovations, refurbishments and conversions. We do not take standalone kitchen or bathroom fit-outs, or individual trade jobs like a rewire on its own.
