Working with DBL …

We are a London-based Design & Build company (Learn more about Design & Build) dedicated to achieving timeless, elegant designs through careful consideration of scale, form and proportion.

Design & Build London work with RIBA Chartered Architects. Who comply with the strict criteria of the Royal Institute of Chartered Architects, covering insurance, health and safety and quality-management systems.  We offer conception to completion, incorporating concept design, planning negotiation, statutory approvals, contractor procurement and management on site.

We are early adopters of the latest technology, we use innovative 3D design and visualisation tools as a standard for all projects. Our experience shows that real-time visualisations and virtual reality are extremely efficient tools for choosing finishes, fixtures and fittings, and simulating natural light.

Our friendly, experienced, highly skilled team can take you step-by-step through the challenge of designing your new space. We’ll collaborate closely with you from the initial drawings, detail design and planning through tender and construction to the successful completion of your project. On time and on budget.

DELIVERING HIGH-QUALITY PROJECTS ON BRIEF, ON TIME AND WITHIN BUDGET.

We offer a wide range of build and refurbishment services and enjoy working on different project types and sizes. We construct new buildings, alter, high-end house renovation, and remodel existing buildings, undertake basement conversions, loft conversions, and kitchen extensions and transform interior spaces.

We guide you through each step of your project from design to completion, allowing you to be involved as much or as little as you want.

BRIEF – We Begin by asking our clients to imagine their lives in the completed house and to describe their desired interaction with it. We then analyse these descriptions in detail to give us a highly defined brief. This brief is then converted into a 3-dimensional simulation which is both revealing and informative, illuminating aspirations, requirements and patterns of habitation.

FORM – From this base, the formal expression emerges, facilitating the requirements of each client’s unique brief. The resulting spaces are easily read as a resolution of the challenges presented by brief and context.

This methodical process strips the design of style and preconceptions, resulting in a completely bespoke and personal design.

MATERIAL – Only once the form and spatial qualities of the design are clarified, we ask: Which materials lend themselves effectively and sustainably to the realisation of the design?

We believe that architecture should provide the backdrop for life and not take centre stage. Life itself is in full colour, so materials are used in their honest, natural state.

We make it easier than ever to access quality design.

We have an incredible team of designers ready to prepare drawings, secure planning permission, and handle building regulations – to name just a few of our services. But 
this is just the start!

No matter the size of your project, or where you’re starting out, DBL has everything you need to unlock 
your home’s potential.

We guide you through each step of your project from design to completion, allowing you to be involved as much or as little as you want.

We would be happy to provide you with a free estimate, and then get started on your house extension – we are ready when you are!

Share your ideas with us, and we can make them become a reality.

Most of the clients ask us this question a lot: what is ballpark figure for a rear house extension?

It is not straight forward because each individual project will be completely different and will depend on a number of factors. If we closely look into multiple factors such as the materials needed, the clients’ vision, the budget and the timeframe before we can give a clear quotation. With that being said, we can give a rough estimate during the site visit meeting. From our previous experience in rear and side extensions, we can give some understanding of what you might expect:

BASIC SINGLE STOREY EXTENSION COST (APPROX)

£1100 – £1,400 PER SQ M2 APPROX.

This figure is a rough idea at what a rear house extension in the Wandsworth area will cost. The range is a correlation between the different level in the finish. There is always the possibility of other costs being incurred when looking at in greater depth.

Lets say you are extending 4M X 5M

So, for your 4 x 5m extension, the build cost at the lowest end of these estimates would be roughly £23,000

+ Add on 10-15% professional fees (architect, planning application, building regs, structural engineer)

+ VAT

Single storey extension = £30,000

HOW ABOUT A DOUBLE STOREY EXTENSION,

It will incur extra costs add 50% extra to the build cost of a single storey extension.

So, £23,000 +50% = £34,500

+ Add on 10-15% for professional fees (architect, planning application, building regs, structural engineer)

+ VAT

Double Storey Extension = £48,000

The above rough estimate will only can be applied to simple extension.

DOES IT INCLUDE A KITCHEN OR BATHROOM?

+ Add say, £5,000 for a bathroom. Costs may be more or (if you are very thrifty) slightly less depending on your sanitary ware and finishes.

+ Add £10,000 for a kitchen (again, completely depends on your specification, £10,000 should get you a lower-mid range kitchen with appliances)

FINISHES AND FITTINGS

Above costs assume modest finishes, fittings, electrics and lighting. Think simple painted walls, carpet floors or possibly engineered oak.

+ If you’re wanting higher-end finishes e.g. tile finishes, fitted joinery etc the costs will increase.

+ Glazing will increase the cost also. Sliding or folding doors are a popular addition to extensions at the moment. You can read our article here for reviews and costs of the best sliding door companies.

ARE THERE ANY COMPLEX SITE CONSTRAINTS?

We will need to include additional costs in your quotation if any of the following apply:

+ Your soil type and ground conditions may present more costly construction methods / techniques.

+ Limited access to the site. Will it be easy for our builders to bring in tools and machinery easily?

+ Existing structure. Are you removing any structural walls? If so there will likely be additional costs for steelwork.

+ Are you moving any pipework, drainage, gas meters?

LOCATION

+ As already mentioned above, in the South East you can expect to pay more than the rest of the UK, and notably more in London.

MATERIALS AND CONSTRUCTION TECHNIQUES

+ Consider the type/ quality of construction materials involved and the type of construction.
