Joachim Louw (CEng MIEI) assesses and designs repairs and alterations in ways that suit solid masonry, lime mortars and timber floors built into the walls. That includes basements, bowed façades, rotten joist ends, removed chimney breasts and openings in spine walls, on protected structures and in Architectural Conservation Areas. The main rule is to understand how the building works before changing it. Cement repairs, rigid steel inserted without thought, and waterproofing that traps moisture have caused more damage to period houses than age has. ## What happens on the first visit On a period house the visit is as much investigation as inspection: how the walls are built, how the floors are carried, what has been altered before, and where moisture is getting in. That shapes every later decision. - Identify wall construction: solid brick, rubble stone, bonding and mortar type - Check floor joists, bearings and any timber built into the walls for decay - Assess façade bowing, cracking and any past tie or strap repairs - Inspect basements for damp, vaults and retaining walls to the street - Note earlier alterations such as removed breasts, openings and extensions - Check protected-structure and ACA status before proposing works ## Common structural issues in Dublin's period houses Bowed and bulging façades, where the front wall has lost its connection to floors and cross walls, are repaired with discreet ties and straps after the cause is understood. Rot in joist ends and wall plates built into damp solid walls is treated by fixing the moisture source, then repairing or splicing the timber, sometimes with hangers. Basements bring retaining walls to the street, vaulted coal stores under the pavement, and damp. Lowering or waterproofing them needs care with what's above and next door. Earlier owners' alterations, such as removed spine walls or chimney breasts with no support, are some of the most common findings, and some of the most urgent. ## Protected structures and conservation areas On a protected structure, works that would materially affect its character need planning permission, including many internal works that would be exempt in an ordinary house. A Section 57 declaration from the council clarifies what is exempt for a particular building. In an Architectural Conservation Area, the council's ACA policy guides external changes. The engineering is designed to suit conservation practice, and to be explained in a way the council's conservation officer can assess. ## What's included - Investigation by a Chartered Engineer - Assessment of walls, floors, roof and basement - Diagnosis of movement and decay causes - Conservation-compatible repair design - Alteration design for openings and extensions - Input for planning and Section 57 applications - Inspections during the works - Signed opinion of compliance Fixed fee confirmed in writing before the visit. ## Modern methods by default, cosmetic repair, or period-appropriate engineering Period houses are damaged most by the wrong fix. | Check | Modern methods by default | Cosmetic repair | Period-appropriate engineering | | --- | --- | --- | --- | | Cause of movement identified | sometimes | No | Yes | | Repairs compatible with lime and solid walls | No | n/a | Yes | | Protected-structure rules considered | No | No | Yes | | Moisture sources addressed | No | No | Yes | Sources - [Dún Laoghaire-Rathdown: Monkstown Architectural Conservation Area](https://dlrcoco.ie/sites/dlrcoco/files/atoms/files/monkstown_aca.pdf) - [An Coimisiún Pleanála: case PL06D.318049 (protected structure, Monkstown)](https://www.pleanala.ie/ga-ie/case/318049) Talk to the engineer 01 270 9764 Mon–Fri 8:00–18:00.

Works that would materially affect the character of a protected structure need permission, even internally. A Section 57 declaration from the planning authority confirms which works are exempt for your particular building. **Why is my Victorian house's front wall bowing?** Usually because the wall has lost restraint from the floors and cross walls, often through decayed joist ends, removed walls inside, or ties that were never there. The engineer establishes whether it's still moving and designs ties or straps to reconnect it. **Can I remove the wall between the two reception rooms in a Georgian or Victorian house?** Structurally, often yes, with a steel beam and proper bearings, but the spine wall usually carries floors above, and on a protected structure it may also need permission. Openings are often kept to a large arch rather than full removal, to protect the plan form. **Should I use cement or lime for repairs to a period house?** For solid brick and stone walls built in lime, use lime-based mortars and renders. Cement is harder and less permeable, traps moisture and causes the brick to decay around it. The engineer specifies the repair materials alongside the structural design. **What areas do you cover?** Dublin and the Greater Dublin Area (Kildare, Meath and Wicklow). Site visits are booked from the Blackrock office. Site visit usually within 5 working days. ## Related services [### Structural Surveys Pre-purchase structural survey with clear limits and a written report before you sign.](https://structuralengineer.ie/structural-survey/) [### Load-Bearing Wall Removal Steel beam and padstone design, propping, inspection and a signed certificate for knock-throughs.](https://structuralengineer.ie/load-bearing-wall-removal/) [### Chimney Breast Removal Gallows brackets or a beam when the breast comes out downstairs but the stack stays.](https://structuralengineer.ie/chimney-breast-removal/) Next step Get a fixed fee for your period property Call [01 270 9764](tel:+35312709764), or send the details and we'll call you back.
