What We Do

Rose Line Premier delivers the widest range of building and construction services, including house extensions, basement conversions and high-end, high-spec refurbishments. Our team of skilled builders and tradespeople are dedicated to delivering exceptional quality and craftsmanship to every project we undertake. Whether you’re looking to extend, renovate or build your dream home, our construction company has the expertise to turn your vision into a reality.

Our construction services include:

New Build Homes —
Our architects and construction team based in West London can work with you to create your ideal space from scratch. We’ll guide you through the design process, ensuring that your new home is not only stylish but also meets your needs. We pride ourselves on only using quality materials and work with trusted suppliers to ensure that every aspect of your home is built to the highest standard.

Home Extensions —
Need more space? We can help you extend your home to maximise the space you have and create the extra room you need. From single-storey extensions to multi-storey builds, we have the expertise to manage the entire construction project from start to finish. Our architectural design and construction team will closely consult and collaborate with you to ensure that your extension matches the style and character you wish to emulate for your home.

Renovations —
If your home is in need of a refresh, our renovation services can help. From modernising your kitchen to updating your bathrooms or reconfiguring your living space, we can help you transform your home into a space that you’re proud of. We’ll keep your vision at the forefront of every stage to make your dream a reality while ensuring that the renovation is completed as efficiently as possible.

Loft Conversions —
If you’re looking to create more space in your home without extending, a loft conversion is a great option that rarely requires planning permission. Our team can help you convert your loft into a functional living space that maximises the room you already have. We’ll take care of everything from planning permission to the final touches, ensuring that the conversion is completed with the utmost quality and care.


We follow the RIBA Plan of Work 2020 and its guidelines:

RIBA Stage 0 & 1

If we price against our own prepared schedule of works and tender package, then we will complete it with our detailed and fully broken down prices.

Should you wish Rose Line Premier to complete the tender package prepared by others then we will complete it with our most competitive and realistic prices.

All our documents and prices are prepared and completed by professional and experienced estimators and/or quantity surveyors.

When completing a third-party pricing schedule we will also submit our supplementary and detailed pricing document. This brings clarity to the pricing process as we expose our rates building up elementary costs for each item within the schedules of work.

Our architectural design and construction teams believe in transparent pricing and will work with you to cost engineer the final scheme as required to fit in line with your specific budget.

Once the pricing has been agreed upon, we sign a contract with you, the deposit invoice is paid and the commencement date is confirmed and secured.

RIBA Stage 2

Before we get to site, we will explain our construction process to you in detail, and if needed, tailor our project management system to meet your specific needs.

Our specialists will organise communication lines between you and the construction team and prepare a detailed project programme, allowing us to ‘live track’ on and off-site operations.

Should you wish us to fully project manage your site, then we will take care of all the parties appointed on your behalf during the planning and design stages and liaise with them to help ensure that you experience a stress and hassle-free construction project.

RIBA Stage 3

We will run and manage the construction process on and off-site for you ensuring its considerate, responsible and fully Building Regulations and Health & Safety compliant.

The site manager will hold weekly meetings with you ensuring you are always informed and up to date with the progress.

If you choose to opt-in, then we will manage the project running account and detail all the valuations prepared for works progressed and materials on site. We follow and implement the Joint Construction Tribunal (JCT) and Federation of Master Builders contract particulars and guidelines ensuring the highest professional standards.

RIBA Stage 4

This occurs when our construction team signs the house back into your care after completing the list of final outstanding items.

12–52+ WEEKS
RIBA Stage 5
Once it’s been six months since your project was finished, our project manager will communicate with you, visit, and agree and compile a snagging list. We will then arrange for all snags to be rectified at a time most convenient for you.
RIBA Stage 4
Once it’s been six months since your project was finished, your project manager will communicate with you and visit to compile a snagging list and arrange a suitable time to carry out the work.
Services and fees

The design and construction are our specialities. This is what we do and have been doing for the last 100 years of combined experience.

We specialise in whole house refurbishment, extensions and basements, and our portfolio of projects ranges from several hundred to millions of pounds. All of our construction projects in West London are design-led, placing an emphasis on quality and design.

No project is the same. Our construction costs are true and competitive and also tailored to the specifics of your project and its location. We will prepare a full works programme for your project indicating major milestones, and dates by which decisions and deliveries will be required.

We will outline and agree on the payment schedule with you staging the payments into fortnightly or monthly intervals with 10% of the deposit required on appointment. You will also hold 5% retention from every payment where 2.5% will be released on practical completion and the final 2.5% once all the snags are completed.

We only price all of our projects once. We do not lower our project prices just to win them.

We have built our reputation on trust and transparency.

Our bespoke system of delivery of your construction projects has already been tested by hundreds of satisfied clients throughout West London and beyond. 

At Rose Line Premier, we are passionate about creating homes that are both beautiful and functional.
