Building & Renovation FAQs | Harpenden & St Albans

Getting Started

What types of building projects do you undertake?

ACR Build specialises in residential extensions, renovations, refurbishments and new builds. We work with homeowners to bring their plans to life; with attention to detail and years of expertise throughout construction.

What areas do you cover?

We are based in Harpenden, Hertfordshire, and undertake residential projects in Harpenden, St Albans and surrounding areas.

Is there a minimum project budget?

Yes. We generally undertake projects with a minimum construction value of £100,000. Our dedicated management approach is best suited to medium and larger-scale residential projects.

When should we get in touch about our project?

As early as possible, ideally while plans are being developed. This helps establish whether the budget, scope and timeline are realistic and gives us the best opportunity to accommodate your preferred start date and design plans. It also means we can work with you to recommend the right, local architects and interior designers.

Do we need architectural drawings before contacting you?

No. We can put you in touch with architects we know and trust. Also, we can also discuss the feasibility of your project at an early stage and may be able to offer an initial budget estimate.

A comprehensive tender generally requires detailed architectural and technical drawings and specifications. Prior to that, we can certainly give you guidance on cost and timelines.

What is a Pre-Purchase review?

We offer a service to clients who are in the process of buying a house locally, and want to know the feasibility and receive a budget indication of the renovation/extension works that they wish to undertake. Most contractors don’t make time or have the set-up for this service. You can find out more here.

Quotations and Budgets

How does your quotation process work?

We begin with a conversation about your requirements, budget and timescales which is usually on-site with our director, Andy Ryder. Depending on your project stage, we can discuss an initial budget assessment or detailed construction tender. We work with external quantity surveying professionals on comprehensive tenders.

How detailed are your quotations?

Detailed tenders are based on the available drawings, specifications and scope of works but we cover all areas of a build line by line, so they can be twenty pages long! Where relevant, we identify allowances, exclusions and areas needing clarification. We encourage clients to review the tender with Andy and we welcome a follow up call or meeting.

How can we compare your quotation with those from other builders?

Quotations may include different materials, specifications, allowances or levels of work. We encourage a like-for-like comparison rather than focusing only on the overall figure. Andy can discuss our scope and clarify differences - he is on hand to help you do exactly that.

What happens if our budget is lower than the initial estimate?

We can discuss reviewing scope, specifications or construction approach, such as alternative materials or prioritising certain areas or staggering a build by stages. Any savings must be assessed for their impact on the design and quality.

Construction and Timelines

How long will our building project take?

Timescales depend on the project size, complexity, structural requirements and refurbishment scope. We discuss an anticipated programme during tendering and review it in greater detail once appointed.

How soon could you start our project?

Availability depends on existing commitments. Please contact us as far ahead as possible of your preferred date, so we can discuss how it aligns with our programme.

Will we need to move out during construction?

That depends on the works planned and their level of disruption especially if it’s a family home. It may be possible to remain at home for some projects or at least for part of the building works. However, with extensive structural works or disruption to kitchens, bathrooms and essential services, moving into temporary accommodation may be more practical.

If we move out, will the project be quicker or cheaper?

Moving out may improve site access, but does not automatically make the build substantially quicker or cheaper. Cost and duration primarily depend on scope, materials, labour and construction sequence. Once appointed, we can review opportunities to accelerate the programme.

What happens if there are unexpected issues during construction?

With retrofit works within existing buildings; concealed structural conditions, drainage complications or undocumented work can and do occur. We aim to explain issues, options and potential cost or programme implications before proceeding with affected works. We’ve seen it all before and guide our clients through such things.

Working with ACR Build

Who will manage our project?

Andy Ryder, our Managing Director and Founder, is involved in the initial consultation and tender review, and remains as a first point of contact throughout each stage of every project. Alexandra Assadian is our Project Support Manager and on hand throughout for anything administrative, including budgeting and ordering. Our Chief Foreman is the man on the ground, and will be there on site throughout the building works.

How will we be kept updated throughout the build?

We aim to maintain regular contact about progress, upcoming decisions and issues needing attention. The frequency and format of updates can be agreed at the start. Some clients want ad-hoc meetings, some prefer weekly meetings. We are always accessible.

Can we choose our own kitchen, bathrooms, tiles and finishes?

Absolutely! Most of our clients prefer to trust us to manage every aspect of a build, including sourcing these items via our recommended local suppliers. However, we can guide clients to select fittings and finishes if they prefer. Above all, we offer expert advice on what to buy and from where.

Do you work with architects and interior designers?

Yes. We regularly collaborate with architects, designers, structural engineers and other specialists involved in residential construction. We have a bank of excellent local people/companies that we can recommend based on client’s specifications.

Payments and Completion

How are payments managed throughout the project?

Payment arrangements are established in the agreed contract and project terms. On a monthly basis, we conduct a valuation and share this with our clients and then bill at the end of the month for works done to date. The initial deposit will be credited to the first invoice.

How are additional costs handled?

Additional costs may arise from requested changes, revised specifications or unforeseen requirements. We aim to communicate the reasons and associated costs clearly.

We also use a budget tracker which has a separate worksheet for any additions/variations from the original tender. These are approved by the client as they occur.

What happens when the building work is finished?

We review remaining works and identify outstanding items. Snagging is part of every project and given our objective is to deliver a finished home to the highest standard possible, we are on hand to address any items for up to a year afterwards.

Can we see examples of your previous projects?

Of course. We encourage prospective clients to explore our completed and ongoing projects and to get in touch about examples relevant to their plans. We have a YouTube channel full of walkthrough videos and testimonials.

Very happy with the quality of work and with the responsiveness of this friendly company.

Garrett Admin

Andy fitted our job into his busy schedule and got the work done to a high standard despite several difficulties. The surveyor stated the work done was “perfect!” What more could you ask? Andy kept us in the loop at all stages. Would definitely recommend.

Alice Knox

Andy and the team at ACR just completed a downstairs renovation project for us - new kitchen, bathroom and living space and the transformation is unbelievable. Their professionalism, communication and attention to detail is impeccable. Our house looks amazing ❤️ Have already been recommending ACR to neighbours and friends.

Rita Scollan

We are pleased with our new double-sized extension. Andy and his team were a pleasure to work with, and the quality of their work was outstanding. We would like to thank them for their excellent service.

Melanie Kerr

I cannot speak highly enough about Andy and the team at ACR who recently completed a full home renovation for us. This included relocating the kitchen to the other side of the house, fitting extra large windows across the back of the house, adding a flat roof, building an outside patio, knocking through rooms to give a more open plan feel and a larger bathroom, fitting a Rako smart lighting system, upgrading the plumbing and making the whole house look amazing! From the first meeting with Andy, I was impressed with his level of communication and engagement, and this continued throughout the 6 months project and after completion. Andy was always on hand to answer any questions I had or suggest alternative solutions for something that wasn’t quite right. His attention to detail is second to none, so much so that he put right the snagging list before I had even given it to him! He managed the project from start to finish and made my life very easy. He works with a very talented team of tradesmen, and I can honestly say that everyone was a highly skilled specialist in their field and did an excellent job. All of who went the extra mile to ensure that their work was to the highest standard and were a pleasure to have in my home. I cannot recommend Andy and the ACR team enough, all my friends and family comment on how my house has been transformed and how amazing it looks, which is down to their hard work. And they finished on time…. even though I added additional work part way through the project! This is the fourth home project I have done and I have never had a builder before Andy who has not gone over their time schedule by several weeks or months. Thank you Andy and the whole team!

Vic Wing

I am so happy with the project Andy and team completed for me. The quality of work was excellent, and working with Andy was smooth, with any unforeseen hurdles explained, solutions identified, and we move on. I would highly recommend ACR Build

Jane Parker

ACR Build, led by Andy Ryder, have enabled us to radically transform this 1972 house into a contemporary, spacious, light and energy efficient home with full solar array and excellent insulation. An awkward side door, step and narrow hallway has been changed into a welcoming, step free, front entrance with wide hallway. A carport and garage, both too narrow for a car, have been demolished and with a rear extension, a large open plan kitchen, diner, lounge has been formed. Full height sliding doors and architecturally interesting 5m long roof light, all with solar glass to prevent the greenhouse effect, give a light airy feel and easy inside-outside living. A new front lounge, new utility room and new washroom complete downstairs. By careful changes to window openings and internal walls upstairs, the four bedrooms, ensuite and family bathroom are all improved spaces, enabling better layouts. Outside improvements now allow the parking of three cars instead of one and at the back a sun trap patio, level with the inside floor height is enhanced by a now level lawn. On this sloping and tight site, ACR Build achieved the depth of foundations the structural engineer required and the team of different trades people they brought in for specialist work were experienced, professional, honest and helpful and worked to a high standard. Andy Ryder was fair in his pricing and gave us honest advice when we faced unexpected issues. He helped us save money where we could. We are enjoying the transformation of the house ACR Build and Andy Ryder have brought about.

Ash Miller

From start to finish I was in safe hands. Andy, was honest all the way through and kept his word as the project progressed. He is extremely knowledgeable and was proactive in making suggestions that would improve the build. It really felt that Andy cared about doing a great job, and that it mattered to him that we were happy too. His team were friendly, helpful and considerate throughout. They always turned up as agreed and worked to schedule. Andy managed my expectation on costs all the way through and provided frequent updates. It came as no surprise that the project was finished on time, on budget and with an excellent finish. Over the years I have worked with several building companies and this was honestly the best experience I've ever had.

Nic Savage

ACR added a kitchen extension to the house we have lived in for thirty years. We stayed in situ throughout. At all stages we found Andy and the guys positive, good humoured and considerate. The quality of the work was excellent, and even when they hit the unexpected, which will always happen in a period house, they were pragmatic and worked through the issues. Andy is repeatedly described as trustworthy in these reviews. I got that impression when deciding to use ACR and it remained to the end of the project.

Shona Crichton

Working with Andy on our extension and full house renovation has been a pleasure. Even from the very beginning stages where we were just gathering quotes and asking a lot of questions, Andy was quick to respond and easy to communicate with. Throughout the project Andy has worked really collaboratively with us, including us in important decisions and keeping us informed of progress. Andy has a great team that he works with and he is hardworking, knowledgeable and has an eye for detail which I really appreciate! He has also provided us with a lot of much needed advice along the way. I wouldn’t hesitate to recommend ACR build.
