I appointed AC Design Solution to act on my behalf in relation to Party Wall matters and worked closely with Zubear throughout the process. His knowledge, expertise, and professionalism were evident from the outset, and he provided clear guidance at every stage. Zubear demonstrated exceptional patience and understanding, particularly as there were delays caused by my architect and structural engineer in providing the necessary information. Despite these challenges, he successfully streamlined the process and ensured that matters progressed efficiently. In addition, Zubear identified several design inaccuracies that could have resulted in complications under the Party Wall etc. Act 1996, allowing these issues to be addressed before they became problematic. I am extremely pleased with the service I received and would have no hesitation in recommending Zubear and AC Design Solution to anyone requiring professional advice and assistance with Party Wall matters.

I've been working with AC Design Solution regularly for all my projects across London and couldn't recommend them highly enough. They handle complex planning applications, basement conversions, loft conversions, house extensions, and mansion house projects — all under one roof. Every single project I've sent them has been approved through planning. The drawings are detailed, the applications are put together properly, and the building regulation drawings and structural engineering calculations are always accurate. As someone sending multiple projects a month, I need a practice I can rely on. AC Design Solution consistently delivers. If you're looking for a practice in London that handles complex planning matters from start to finish — planning permission, building regulations, and structural engineering — these are the people to use.

Excellent service. They know their business and give good advice. I've used AC Design Solution for a wide range of projects across London, Kent, Essex, and beyond — and they handle everything professionally wherever the project is located. From single storey extensions and architectural design to load-bearing wall removal, structural reports, and party wall surveyor services — they cover the full scope of what you need. The structural calculations and impact assessments are always detailed and submitted on time. The building regulation drawings are thorough and the planning applications have gone through without problems. What I like most is that you're dealing with one practice for everything rather than chasing multiple contractors. If you need architectural design, a structural engineer, or a party wall surveyor anywhere across London, Essex, Kent, or the surrounding areas — AC Design Solution are reliable, knowledgeable, and get the job done right.Thank

I appointed AC Design Solutions for a challenging new build project - demolishing an existing house and replacing it with 7 new flats in Isleworth. The team provided a comprehensive service including architectural design, structural engineering calculations, building regulations drawings, and preparation of all the technical reports required for planning (drainage, energy, daylight/sunlight, arboricultural, etc.). The project was taken to Hounslow Planning Committee and we achieved unanimous approval on the first attempt. AC Design Solutions were very responsive throughout, handled all the pre-application consultations, and prepared a strong case that addressed all the planning concerns. Their knowledge of local planning policies and building regulations was excellent, and they coordinated all the specialist consultants we needed. The building regulations drawings were detailed and compliant, ready for submission. I would highly recommend AC Design Solutions for residential development projects in West London. Really pleased to have these guys on my team - they are absolutely on the ball, and I look forward to doing many more projects with them in expansion of my portfolio.

Structural Engineering Services we offer

How We Deliver Quality Structural Design

Delivery of quality comes from collaborative working and coordination. Our consultancy maintains close collaboration with architects to ensure structural systems work with design intent. We work with developers to achieve cost-effective engineering services without compromising quality. By coordinating multi-disciplinary teams, we provide innovative structural engineering design and delivery that works in practice.

Building Safety and Audit Services

Safety is a core part of our structural engineering services. Our consultancy ensures that structures comply with current technical standards throughout their life. This applies to new structural engineering projects as well as existing buildings that require audit, inspection and advisory services.

Our engineers run detailed building audits, carrying out risk assessments to identify potential issues before they become serious. Through careful inspection, structural analysis, and clear reporting, we help clients make informed decisions across different industry sectors. Where projects involve excavation or basement works, our basement impact assessments identify risks to neighbouring structures before work begins.

Fire engineering is built into our structural engineering design services from the outset. We ensure structures maintain stability during fire events, integrating fire and structural design for better performance. Modern methods of construction such as modular steel, timber frames, and precast concrete require specialist understanding, and our consultancy provides the technical knowledge and experience needed to adopt these sustainable techniques effectively.

For existing buildings, our audit and inspection services reveal hidden structural issues. We assess concrete deterioration, timber decay, load capacity, and other structural concerns. Our structural survey London service provides clear strategies for remediation and structural strengthening using modern methods alongside traditional surveying.

Structural Engineering Design and Delivery

Good structural engineering design balances technical performance with architectural ambition. Our consultancy delivers structural drawings and calculations that support creative solutions while remaining cost-effective and sustainable.

Every project starts with foundation design. We consider sustainability and durability from the outset. Moving up through the structure, we use steel, concrete and timber innovatively to create efficient buildings that meet environmental targets. This combination of structural engineering expertise and technical design ensures high-quality delivery.

Load-bearing wall removal is a good example of our approach to residential structural engineering projects. We inspect existing structures, calculate loads, and design suitable supports to achieve open-plan layouts without compromising safety. Every project includes full structural engineering design documentation: calculations, drawings, and specifications for compliant construction.

For large tower and commercial buildings, our RC frame engineering shows how innovation and technical expertise work together. Our house structural engineer team coordinates the entire structural system with architectural, mechanical, and electrical design to optimise service routes, load paths and floor zones.

Retaining walls are another area where structural engineering design and delivery make a difference. We select the best solution for each structure, whether that’s reinforced concrete, timber cribs or gabion baskets, always considering sustainability and cost efficiency.

Civil & Drainage

Designing site infrastructure including drainage systems, utilities, and external works for compliant development.

Defect Identification and Structural Advisory Services

Existing buildings often develop defects over time. Our structural engineering consultants specialise in identifying and resolving structural problems through technical analysis and careful inspection. Properties showing signs of subsidence require early assessment — delays can significantly increase remediation costs.

We use visual inspection, non-destructive testing, and structural assessment to diagnose issues accurately. Our engineering services cover crack monitoring, movement assessment, and evaluation of material degradation in both concrete and timber structures.

Once the diagnosis is complete, our structural engineering design services provide cost-effective solutions ranging from minor repairs to major strengthening. Where chimney breasts form part of the structure, our cost to remove chimney breast service covers full structural design and specification. We coordinate with specialist contractors to ensure successful delivery using both traditional methods and modern strengthening techniques, including carbon fibre reinforcement and post-tensioning.
