Guide Pricing for 20m2 Buildings

Everything we build is bespoke

At Annexe Spaces, we provide bespoke solutions that are tailored to meet our client’s specific needs, in terms of flexible size, layout and specification. We believe a tailored solution is a far better investment, and the small additional cost is far outweighed by the significant benefits.

The Annexe Twenty simply provides you with a starting point to gauge pricing, and how the space can be used. 

We offer both flat and pitched roofs models with wide range of stylish contemporary finishes.

See the table below for guide pricing, just to give you an idea.

Kitchen appliances

We offer a full range of modern energy efficient appliances, including fridge/freezers, electric ovens, hobs (halogen and induction), microwave ovens, extractors, dishwashers – all the equipment would expect, and indeed desire, in a modern kitchen. Prices available on request.

All percentages above are approximate and are based on a standard specification and individual project content.

Location charges: The Spaces Group design and build across the UK mainland (not including Scotland unfortunately). We do charge a variable location fee for working at distance (up to a maximum of 10% of the overall project value). This charge covers our additional expenses, and relates to the distance from our business hub in North London.

How we price: Quality and value for money is everyone’s priority, and is our mantra. We will not compromise on either, and by operating without expensive showrooms and offices, we are proud to offer consistent cost efficient bespoke solutions. We provide a complete service from survey and design, to the delivery of a ready to use building including all services. 

Moreover, we operate a policy of complete transparency with our pricing. We approach every build with flexibility and work hard to design the best possible bespoke solution for each client within their budget.

NOTE: The ranges and specifications detailed above are purely intended as a guide, and we are happy to provide a no obligation free survey and consultation.
